Political and Commercial Geology and the World’s Mineral Resources

PREFACE

The purpose of the accompanying series of studies is to shed light upon the vast importance of commercial control of raw materials by different powers, or by the citizens of those powers, through invested capital. The question of domestic and foreign governmental policies of the United States is closely involved. It appeared to many of us who were engaged (as all the authors of these papers were) in studying the mineral problems during the war, that our Government had never grasped the vast political significance of commercial domination, and especially of the control of mineral wealth; and that other more seasoned nations had done so, and thereby affected the interests of America and her policy very deeply, without her being aware of the circumstance.

With the rapid increase of the world’s population and the exploring and exploiting of the hitherto undeveloped natural resources, competition for this wealth has become and will still become keener. In past ages war, pestilence, and starvation held down the earth’s population; and in the last few years all these grim spectres have returned in force, suggesting the possibility of a permanent return of the old primitive days. Nevertheless, modern science and organization, if not quenched by vast social disorders, will so safeguard life, as in recent times, that the world is in a fair way to become crowded. All of us, like Germany, yearn for our “place in the sun,” and our share of comfort and power. Of all the fundamental necessities for this, nothing is so much in the nature of a fixed and unmultipliable quality as the metals; they constitute the basis and foundation of our modern civilization and power over man and natural forces. Other raw materials are of vegetable or animal origin; they propagate and duplicate themselves in successive incarnations according to the law of life; they are born in some magical fashion of air and water, with a minimum of the earth, and they return their loans faithfully to air and water and earth with the passing of each generation and the dawning of a new. There is the hint of such a law of growth in the mineral kingdom, but it is so vastly slow that the evanescent animal man has no personal interest in it; for all his purposes and by all his standards of measurement it is inert, and these riches, once dug and used, will never again be available. The treasures of commercially valuable ore-deposits have been hid by nature whimsically throughout the earth, here and there, by no rule of geography or latitude, and with a great disregard of equality. A nation’s needs or desires for mineral wealth have no stated relation to its actual mineral possessions; what it needs is often in the territory of another nation which does not need it. Commerce is thus born, and the nation which must have the metal or ore in question backs up its commerce and helps it to fasten its claims for permanent control of the deposits in question, by legislation, by diplomacy, and, if need be, by war. In the case of war, the metallic prize falls to the strongest—usually the nation which before, through its necessities, exercised only commercial control, but which, as the result of the trial of strength, now frankly asserts its sovereignty.

Have we as Americans realized these forces? Absolutely not, I should say. How many realize that the Alsace-Lorraine question is and was not a sentimental one, but a struggle for the greatest iron deposits of Europe and the second largest in the world, which gave Germany her immense growth and power, and may now transfer that wealth and power to France? That the dispute between Poland and Germany as to Upper Silesia is not a question of nationality, sentiment, or even territory, but concerns the greatest coal field of Europe as well as great deposits of lead and zinc? If Poland gets this, she may rival Germany in wealth and importance; if Germany loses it, she may drop into the position of a second-rate power, now that she has also had to give up Alsace-Lorraine. To submit such a question to the vote of the native population is of the same order of fitness as tossing a coin for it; but how many of us have understood this? Population shifts and changes, swells or shrinks, may be at one time predominantly Polish and at another time mainly German; but the coal deposits are fixed. To clarify these things we should in place of Silesia say Coal, in the place of Alsace-Lorraine, Iron, and so on.

The reason we have not realized these facts is on account of our own vast mineral wealth, so abundant that not till recently has American capital and enterprise found it necessary to adventure into the outside world, as the European nations had long ago done. Their natural wealth was limited so that they have become familiar with those fundamental principles and laws of which we have been unconscious. From this has arisen European foreign policies, the protection of their national commerce and national capital in foreign enterprises and consequently at home; governmental participation in business combinations, as in Germany, England, France, and Italy; while the United States has been engaged in “trust-busting” and has neglected the protection of its investors in foreign countries. This illustrates the difference between European diplomacy and American guilelessness. How well this played into the hands of foreign powers it is unnecessary to explain. The spectacle of the United States maintaining a Monroe Doctrine of protection over Latin-American republics which she took no vigorous steps to unite with her by the powerful bonds of commerce, must well have excited the amusement of those European commercial nations like Germany who have been strengthening themselves in those countries by the closest commercial, and hence political, ties.

This volume simply takes up the study of the actual situation, as to the distribution and ownership of mineral supplies in the world, and the author of each chapter is a well-known specialist.

First is considered the question of petroleum, source of power and light, the key to the mastery of the air, and, on account of its fluid and easily transportable condition, of extraordinary future importance. Next are taken up the great fuel mineral, coal, and its ally, the great metallic mineral, iron, which must go together for the manufacture of iron and steel, the backbone of all our mechanical achievements. Next come those metals indispensable in steel making and in the manufacture of specially hard or tough steels. These are of great importance, and include manganese, chromium, nickel, tungsten, vanadium, antimony, molybdenum, uranium, and zirconium. Radium is closely associated with uranium and is considered with it. Closely allied with zirconium are thorium and mesothorium, and their treatment therefore closely follows that of zirconium.

The next great group is that of the major metals, other than iron and the ferro-alloy metals: copper, lead, zinc, tin and mercury, and aluminum. Aluminum ores are used not only as sources of the metal, but for the manufacture of refractories and abrasives. Therefore they are classed partly with the metallic and partly with the non-metallic minerals; and the other non-metallic minerals, used likewise for abrasives, refractories, and other uses—such minerals as emery and corundum, magnesite, graphite, mica, and asbestos—follow.

The next great group is that of the fertilizer minerals—phosphate rock, potash, nitrates and nitrogen, and pyrite and sulphur, all essential for agriculture.

The last group is that of the precious metals, gold, silver, and platinum, essential for coinage and in the arts.

These various studies are essentially both inclusive and elementary: together they form almost the first contribution to the branch of investigation—that of the relation of geology to industry, commerce, and political economy—which they cover; and it is natural that beginnings should be rather crude. Moreover, many of the chapters were written a year or more previous to the publication of the volume, and although brought to date to the extent possible in the brief time available, are considered inadequate by the authors themselves. Apologies for shortcomings and possible inaccuracies are therefore very much in order. Nevertheless, it is felt that the volume merits publication, and that the beginning here made is far better than no start at all.

Coal and iron are the backbone of industrial civilization, and should be considered first in any attempt to analyze the ownership and control, as between nations, of the world’s mineral resources. Kin to coal in growing importance, however, is the lighter, fluid and volatile mineral substance, petroleum, whose significance is vast and as yet not wholly defined. More easily transportable than coal, and yielding refined products whose explosive action in internal-combustion engines furnishes greater power in proportion to weight than was once deemed possible, petroleum and its products, apart from their immense direct economic importance, may, in the automobile, the submarine, and the air plane, and through numerous other applications, control strategically, from a nationalistic standpoint, the more inert foundations of civilization. Moreover, the use of crude petroleum as fuel, especially for ships, is of the most vital importance in these days of greater competitive plans for expanding world-wide commerce, and establishing the strength and ready efficiency of navies. Great maritime nations must have, for their oil-burning ships, oil-bunkering stations under their own control in all parts of the world where they wish their commerce to dominate, and their navies to protect their interests efficiently.

The recognition by certain strong and aggressive nationalities of this critical factor has brought about a situation that is perhaps unparalleled in the mineral history of the world. Coal and iron have always been decidedly static as to control—they have remained largely under the supervision and direction of the countries in which they occur. Transportation costs, the conjunction of iron and coal deposits, and other factors have prevented these minerals, in spite of their vast importance, from being fully used as a world commodity. By contrast, petroleum is coming to be universal, like gold, in its acceptance and applicability; but, unlike gold, it is essential in the highest degree to the advance of modern civilization. The fluidity of this mineral, its consequent amazingly cheap transportation and handling by pipe lines, the completeness with which it can be utilized, all combine toward making it in the future the crucial factor of commercial and of political control. Moreover, this fluidity of form and ease of application facilitate the control of petroleum by vast commercial organizations, like the Standard Oil of America, and others in various parts of the world; and even make its world control feasible and probable. Recognizing this tendency, many nations, like England, France, Holland, Argentina, and Mexico, have taken steps looking toward a partial nationalization of their petroleum resources, in order to protect themselves against foreign commercial aggression in this particular. England has gone farthest in this direction, and has reached and is reaching out aggressively into other countries to secure, through commercial control, backed where necessary by political pressure, a world empire of petroleum to serve her world-wide colonial empire. The United States, on the other hand, has dominated the world’s petroleum industry through her own vast resources, worked by interests which have grown without conscious governmental help or even in spite of governmental and popular opposition, and have reached out and secured footholds in other countries.

In the past the mineral development of the world has led to great changes in political sovereignty. Important as these have been, the events that may result from the nationalistic competitive exploitation and control of the world’s petroleum supply bid fair to exceed in importance all similar changes of the past. The perception of the problem and of the necessity, and the advantage of the initiative, naturally belongs to those nations with restricted area and resources, that have grown great by trading and by exploiting the resources of other countries. Such a nation, for example, is England, a country that is fortunately the natural ally of the United States. By contrast, in the United States, a nation concerned hitherto only with the development of its own vast resources, commercial enterprise in foreign countries has been backed by no fixed national policy, and indeed has often been treated as unworthy. In the new international era that was initiated by the World War, however, this policy of Chinese self-sufficiency and exclusion can not be safely continued, and the United States must not only perceive clearly the tendencies and movements of other nationalities, but consider how best to direct its own commercial and political plans so as to uphold its independence and power. Such a policy would naturally lead to international agreements as to the distribution and division of petroleum lands, resources, and production, and probably no one thing would contribute more to the promotion of frank understanding between nations and the removal of obstacles to permanent peace.

Mr. Northrop’s paper follows:

In its crude or semi-refined state, petroleum is extensively utilized as fuel under locomotive and marine boilers and to a small extent in internal-combustion engines of the Diesel type. Certain grades of petroleum are utilized in the crude state as lubricants.

The principal use of petroleum is for the manufacture of refined products, of which the number and uses are legion. The lightest gravity, etherial products are employed as anaesthetics in surgery. The gasolines are the universal fuels of internal-combustion engines, and the naphthas are widely used as solvents and for blending with raw casinghead gasoline in the manufacture of commercial gasoline. The kerosene group includes a variety of products utilized primarily as illuminants, but in annually increasing quantities as fuel in farm tractors. The lubricating oils and the greases derived from petroleum are indispensable to the operation of all types of machinery. The waxes derived from petroleum of paraffin base are utilized in many forms as preservatives and as sources of illumination, and in the last three years have become indispensable constituents of surgical dressings in the treatment of burns. Petroleum coke, because of its purity, is in demand for use in certain metallurgical processes and for the manufacture of battery carbons and arc-light pencils. Fuel oils obtained as by-products of petroleum refining satisfy the fuel needs of many industrial plants, railroads and ocean steamers. Road oils, as the name implies, are employed for minimizing dust on streets and highways; and artificial asphalt, a product of certain types of petroleum, has in many localities superseded the use of other forms of asphalt for paving purposes.

—For petroleum as a fuel under boilers in the generation of steam there are numerous substitutes, including wood, charcoal, coal, peat, natural gas, artificial gas, and electricity; as a fuel in internal-combustion engines some demonstrated substitutes are natural gas, artificial gas, benzol, and alcohol, and in the Diesel type of engine certain vegetable and fish oils can be utilized.

For illuminating purposes, animal fats, oils distilled from coal, natural gas, artificial gas, acetylene gas and electricity may be substituted for kerosene.

For certain types of lubrication carefully refined vegetable and mineral oils are acceptable, but for lubricating high-speed bearings and for all lubrication in the presence of high temperature and of steam no satisfactory substitutes for mineral lubricants derived from petroleum are known.

Substitutes for petroleum asphalt are available in the form of native asphalts, bituminous rocks, and coal-tar residues. For petrolatum, animal fats and vegetable oils can be substituted, and for paraffin wax, ozokerite might be made to satisfy such essential requirements as could not be met by refrigeration or by vegetable and animal oils.

Probable changes in practice that may be expected to affect the petroleum industry within the next ten years include an increased dependence by oil producers on geologic investigations in advance of drilling, the development of methods for deeper drilling than is now practicable, and the more efficient handling of individual wells and of entire properties, with a view to the ultimate recovery, at minimum cost, of a higher percentage of the oil originally present.

The tendency toward amalgamation of individual producing, transporting, refining and marketing interests into strong units capable of competition in domestic and foreign markets on relatively equal terms with each other and with pre-existing combinations of equivalent strength will doubtless increase, and with the growing strength of the several units will come an efficient and thorough quest for petroleum in all parts of the world.

In the refining of petroleum it is probable that methods will be devised and perfected for recovering more of the light-gravity products from low-grade petroleum and for the conversion of the less-salable products of petroleum into products of greatest current demand. Moreover, it is believed that internal-combustion engines will be so modified as to run successfully on petroleum products of lower volatility than gasoline. The use of petroleum as railroad, marine, and industrial fuel is destined to increase enormously in the next decade.

Although an important contributor to the oil-supply of Great Britain, the shale-oil industry has received little attention in recent years outside of Scotland. Investigations by the United States Geological Survey have demonstrated that the United States contains vast deposits of oil shale in Utah, Colorado, Wyoming and Nevada, much of which will average higher in oil content than the Scottish shale. Efforts already begun to develop methods for the recovery of shale oil on a commercial scale in the United States will undoubtedly result in the establishment of a shale-oil industry in this country within the next two or three years. The future growth of this industry will depend largely on the rapidity of the decline in the domestic production of petroleum.

Commercial accumulations of petroleum are everywhere restricted to strata of sedimentary origin. In the United States petroleum is produced commercially from strata of all periods from Cambrian to Quaternary, the most prolific sources being in strata of the Carboniferous and Tertiary systems. The geological age of the chief sources of petroleum production in each of the other oil-producing countries of the world is indicated in the table following:

Table 1.—Geologic Age of Petroleum-bearing Formations

From the foregoing table one might conclude that a direct relation exists between the distribution of Tertiary rocks and the supply of petroleum, but in the United States, which produces two-thirds of the world’s current supply, the quest for petroleum has, under scientific direction, included the entire range of the stratigraphic column, and has found petroleum in considerable quantities in the rocks of each geologic system younger than the Cambrian.

The fact that seeps and other surface indications of petroleum are generally more pronounced in the relatively younger Mesozoic strata than in the older Paleozoic formations, and the further fact that geologic exploration for oil and gas in countries other than the United States has been restricted in the main to areas containing the most pronounced indications of petroleum, tend to account for the predominance of the Tertiary system in the foregoing table and to indicate the fallacy of attempts to estimate the world’s reserves of petroleum on stratigraphic evidence alone.

Despite the broad geologic range of petroleum, its occurrence in specific members, formations, groups, series or systems is by no means universal. On the contrary, its occurrence is restricted to specific localities in which are fulfilled certain variable relations, as yet but little understood, that involve (1) the constitution, sequence and content of organic matter of the sediments; (2) the nature and degree of metamorphism they have undergone; (3) their structure; and (4) their degree of saturation with salt water. Because the most detailed geologic work is insufficient to provide a basis for the appropriate evaluation of the numerous factors involved, and because only a relatively small percentage of the areas of sedimentary rocks in the world have been examined geologically in appreciable detail, any estimate of the future supply of petroleum in the world is peculiarly hazardous.

The geographical distribution of petroleum is as wide relatively as its geologic range. The oil fields of present commercial significance are situated, in the order of their importance as contributors to the world’s production of petroleum in 1917, in the United States, Russia, Galicia, Mexico, Dutch East Indies, India, Persia, Japan and Formosa, Roumania, Peru, Trinidad, Argentina, Egypt, Germany, Canada, Venezuela and Italy. Small quantities of petroleum have also been reported from Guatemala, Honduras, Costa Rica, Panama, Haiti, Porto Rico, Bolivia, Chile, Spain, Arabia, China, Australia, Papua, Philippine Islands, Nigeria, Belgian Congo, Gold Coast, Madagascar, and elsewhere. The geographical distribution of petroleum in the world is shown on the accompanying map. (Plate I.)

Plate I.—Geographical distribution of the producing petroleum fields of the world. By John D. Northrop.

In the opinion of the author the most conspicuous developments of the world’s supply of petroleum in the next decade will take place in the countries that border the Caribbean Sea and the Gulf of Mexico. The trend in this direction is unmistakable. From 1913 to 1917, the annual production of petroleum in Mexico increased from 21,000,000 barrels to 56,000,000 barrels, and the potentialities of future production in that country have been demonstrated to be almost beyond comprehension. The output, originally considered valuable only as a source of fuel oil, is now yielding, by modern refining methods, increasingly important percentages of illuminating oils and gasoline. The only obstacles to enormously increased production are unsettled political conditions and inadequate facilities for marine transportation. These obstacles will doubtless be overcome within the next few years, and barring unforeseen contingencies Mexico will soon rank second among the oil-producing countries of the world.[2] Judged by the results of exploratory work already done in Venezuela and Colombia, both of those countries are destined to contribute appreciably to the world’s supply of petroleum within the next decade. Recently Colombia has given enough evidence of ability to furnish high-grade petroleum from wells of large individual capacity to warrant the large interests holding concessions there to exert every effort to overcome the adverse natural conditions that have so long barred the way to exploitation. Enough drilling has already been done in Venezuela to demonstrate that the resources of heavy-gravity asphalt-base petroleum in that country are large, and the recent installation of a modern petroleum refinery for the treatment of these oils on the island of Curacao, off the Venezuelan coast, has provided the market necessary to active field development.

In Trinidad the production of petroleum exceeds 1,500,000 barrels a year and has doubled in the last few years. With the increased facilities for ocean transport of petroleum that are becoming available, a large output is assured.

Cuba is not expected to become an important producer of petroleum, and present knowledge concerning the petroleum resources of the Central American countries is not such as to warrant the belief that oil fields of material consequence will be developed in any of them.

Petroleum production in the United States is expected to reach its maximum within the next two or three years and to decline steadily thereafter, although this country is expected to remain the leading oil-producing country of the world for the greater part, if not all, of the coming decade.

As regards those oil-producing countries of North and South America that have not been already mentioned, no significant changes in their present status are anticipated.

The petroleum resources of Russia (including Asiatic Russia) are believed sufficient to assure that country retaining its position as the leading producer of petroleum in the Eastern Hemisphere far beyond the next decade. During the last few years the output has been obtained under increasing difficulties, and as a consequence there has been no measure either of present productive capacity or of potentialities. Concerning the future of Russia as a source of petroleum Arnold[3] says: “Such large areas, both in European and Asiatic Russia, yield unmistakable evidence of the presence of oil in large quantities that it is to this country, among those of Europe and Asia, to which the future must look for a supply.”

Russia being endowed with petroleum reserves, both proved and prospective, of great magnitude, the ultimate position of that country as the leading oil-producer of the world seems reasonably assured. Its immediate future is too intimately dependent on the progress from political turmoil to warrant a forecast.

The oil fields of both Roumania and Galicia are believed to have passed their maximum yield, and the possibilities of opening new fields of consequence in those countries are not considered large enough to justify a forecast of anything but a moderate decline of production in future years. No material change in the status of the negligible oil fields of Italy or of Alsace is anticipated at any time in the future.

With regard to the situation in Asia, the writer believes that the next decade will witness a steady increase in the output of petroleum in India, and the probable development of one or more important oil fields in Persia and possibly of fields in Asia Minor, Turkestan and China. In Oceania the same period will doubtless witness a material increase in the production of petroleum in Japan and Formosa and in the Dutch East Indies, together with the possible opening of new fields in Papua. Africa will doubtless receive considerable attention from oil operators in the next ten years, but on the basis of available evidence the results obtained in that period will probably not be large enough to affect the petroleum situation of the world.

The status of the political control of the world’s output of petroleum in 1917, as determined by the best data now available, is indicated in the table following.

The accompanying diagram (Figure 1) shows the proportion of the world’s production of petroleum contributed annually by each of the principal producing countries in each of the last ten years.

Table 2.—Political Control of the World’s Production of Petroleum in 1917

Fig. 1.—Proportion of the world’s output of petroleum contributed annually by each of the chief producing countries, 1908-1917.

Aside from the control exercised by Great Britain through its protectorate relation over the petroleum resources of Egypt, control of the petroleum resources of the various countries is mainly by virtue of state sovereignty. This political control is in proportion to the strength of the government in the country exercising it. Recent developments whereby the British government becomes the majority stockholder of a corporation controlling the oil resources of Persia, practically transfer the political control, as well as the commercial control, of Persian petroleum from Persia to England. Mexico’s recently attempted firm political control of her vast petroleum resources depends for its success upon her diplomatic ability in dealing with the stronger governments of England and the United States, whose nationals have acquired a commercial control that is threatened by Mexico’s new and decided nationalistic policy.

The commercial control of the world’s production of petroleum, as far as nations are involved, is determined in the main through direct ownership, of lands, leases and concessions, or by the control, through holding corporations, of subsidiary companies holding fee, leases, mineral rights or concessions of petroleum land. Except in Argentina, where the domestic petroleum industry is owned and operated by the state; in Germany, where the government participates directly in the financing of petroleum enterprises through the Deutsche Bank; and in Persia, where the British government owns a substantial interest in a company owning and operating extensive concessions, the commercial control of the petroleum industry is determined almost wholly by aggregations of private capital acting in their own interests.

Table 3.—Nationality and Extent of Control of Dominant Interest

So far as the author is aware, Canada is the only country in which the petroleum industry may be said to be controlled by foreign (United States) interests, this control being by virtue of an essential monopoly of pipe-line and refining facilities.

The preceding table shows, according to the best information available, the nationality and approximate extent of control exercised by the dominant interest in each of the principal oil-producing countries of the world in 1917.

The accompanying diagram (Figure 2) shows graphically the approximate commercial control of the world’s production of petroleum in 1917.

Fig. 2.—Approximate commercial control of the world’s production of petroleum in 1917.

Commercial control of the petroleum industry in the United States is in the hands of the so-called “Standard Oil Group” of companies, through their control of most of the great pipe-line systems of the country, of probably 75 per cent. of the refining facilities and of a substantial part of the actual production. Other domestic interests having important shares in the control of the petroleum industry in the United States include the Southern Pacific Railroad Co., Cities Service Co. (Doherty interests), General Petroleum Corporation, Gulf Oil Corporation, Ohio Cities Gas Co., Cosden & Co., Sinclair Oil & Refining Corporation, The Sun Co., the Texas Co., the Tide Water Oil Co., and the Union Oil Co. Foreign interests in the United States include purely British companies, which control a production of about 2,000,000 barrels a year; British-Dutch companies represented by the Royal Dutch-Shell Syndicate, which control a production of about 9,000,000 barrels a year, together with refining and marketing facilities; and Franco-Belgian companies controlling a yearly production of about 1,000,000 barrels. Aside from the very probable holdings by individual Germans of shares in companies engaged in one or more phases of the petroleum industry of the United States, the author is aware of no organized German interest in any phase of the domestic industry.

Commercial control of the petroleum industry of Russia is, under the political conditions now existing in central Europe, largely a matter of speculation. As nearly as can be ascertained, the dominant control is in the hands of purely British, Franco-British, and British-Dutch (Royal Dutch-Shell Syndicate) interests. Certain of the second-named interests are allied closely with an additional group of capitalists represented by the firm Nobel Bros., of much importance, the present control of which is by no means clear, from the literature available on the subject. Though originally Swedish, the financial interests now involved in Nobel Bros. are believed to include representatives of financial groups in England, France, and Germany as well, with control probably lying with the Anglo-Swedish interests. Before the war, direct German interest in Russian petroleum included control by the Deutsche Bank through a Belgian company (the Petrole de Grosny) of the important producing and refining company, A. I. Akverdoff & Co., control of which is now in British or British-Dutch hands. As in the United States, a considerable part of the actual production of petroleum in Russia is distributed among a large number of individually weak companies, dominated, through the control of pipe-line or refining facilities, by one or another of the principal groups.

Of considerable importance in Russian petroleum affairs at one time was the European Petroleum Union, organized for combat in the world markets with the Standard Oil trust. This union included among others such important petroleum operators as Nobel Bros., the Rothschild interests (now Dutch-Shell), Mantaschoff (now Russian General Oil Corporation) (British), and the Deutsche Bank, the latter controlling Akverdoff and Spies in Russia, together with important companies in Roumania and Galicia. How far this union controlled the affairs of its constituent companies is not evident from available data, and its present influence on companies now operating in Russia is uncertain.

Conditions in Russia make impossible any definite statement on the petroleum situation. A decree of the Bolsheviki government, dated June 20, 1918, on the nationalization of the petroleum industry, declared as the property of the state all movable and immovable property employed in and belonging to that industry. Trading in oil was declared a state monopoly and was delegated to the chief petroleum committee of the fuel department of the supreme Council of National Economy. As the chief producing areas are now under British military control, this decree is ineffective.

Commercial control of petroleum in Mexico is divided among United States, British, and British-Dutch interests, which controlled about 65, 30 and 2 per cent., respectively, of the production in 1917. The interests of the United States include the Doheny group, operating principally as the Huasteca and Mexican Petroleum companies; the Standard Oil Co. of New Jersey, operating as the Penn-Mex Fuel Co.; the Sinclair interests, operating as the Freeport and Mexican Fuel Oil Co.; the Texas Co.; Gulf Co.; Southern Pacific Railroad; and others. The British interests are represented by the Pearsons, operating as the Mexican Eagle Oil Co.; and the British-Dutch interests by La Corona Petroleum Co., and Chijoles Oil, Ltd., controlled by the Royal Dutch-Shell Syndicate. No exclusively German interests are known to hold a substantial portion of any important company operating in Mexico.

Formerly concessions were freely granted to foreign individuals and companies for the exploitation of mineral deposits, and oil lands were sold by the native owners to foreigners. Article 27 of the constitution of 1917 expressly forbids any but Mexican companies acquiring directly or operating directly petroleum lands in Mexico.

All recent concessions for the exploitation of oil properties contain a provision stating that the concession will be declared null if any of the rights are transferred to any foreign government. The provisions and the intent of a series of presidential decrees issued on February 19, 1918, July 8, 1918, July 31, 1918, and August 1, 1918, are to nationalize all petroleum lands and to permit them to be worked only by Mexican citizens or by companies that agree to consider themselves Mexican and further agree not to invoke the protection of their governments. A bill was presented in December, 1918, to carry out Article 27 of the new constitution, but thus far no action has been taken in the matter. The decrees and legislation growing out of Article 27 have been protested by the chief petroleum companies operating in Mexico and by their respective governments.

Commercial control of the petroleum resources of the Dutch East Indies is in the hands of the Royal Dutch-Shell Syndicate and is essentially absolute by reason of the restrictions contained in the Netherlands East India Mining Act and subsequent supplements on foreign acquisition of mining rights in the East Indian Archipelago. Actual control is in the hands of the Bataafsche Petroleum Maatschappij, which has a capital of $56,000,000 divided into five shares, three of which are owned by the Royal Dutch Petroleum Co., and two by the Shell Transport Trading Co. (British). Purely British interests control an inconsequential production of petroleum in British North Borneo and in Sarawak.

Prospecting licenses and concessions are granted only to Dutch subjects and to Dutch companies. It is officially stated that the object of these restrictions is not to exclude foreign capital; this is precisely their effect, and on account of the economic monopoly which the Royal Dutch-Shell now has of the petroleum industry of the Dutch East Indies, it would be very difficult for any new enterprise to gain a foothold.

Commercial control of the petroleum resources of India is exercised by the Burma Oil Co. through its dominance of production, refineries, and pipe-line facilities, and by reason of agreements as to marketing with its principal competitor, the British Burma Petroleum Co., both controlled by British capital. The Burma Oil Co. is allied with, if not directly controlled by, a group of British financiers, one or more of whom is interested in companies in Trinidad and in Persia.

During the war the petroleum industry of Roumania was temporarily wholly in control of German and Austrian interests. The advanced stage of development of the oil fields prior to the war and the intentional damage, much of which is irreparable, wrought in the fields by British detachments in 1916, when capture of the fields by Austro-German forces became inevitable, are believed, however, to have deprived Germany of a large part of the fruits of her conquest, as it is considered doubtful if the Roumanian fields can ever again be made to yield petroleum at the pre-war rate of 12,000,000 barrels per annum.

The American Petroleum Institute states that “Roumania is considering the erection of a state monopoly of both production and distribution on the ruins of the monopoly which Germany sought to establish there but was compelled by the armistice to renounce.”

Prior to the war Dutch or rather British-Dutch (Dutch-Shell) interests controlled about 30 per cent. of the annual production of petroleum in Roumania, German interests about 26 per cent., United States interests (Standard Oil Co. of New Jersey) about 18 per cent., French interests about 16 per cent., purely British interests about 6 per cent., and Belgian and Roumanian interests the remainder.

Through the Austrian “Society Gaz” and the German “Deutsche Erdoel Aktien-gesellschaft,” German interests have dominated the petroleum industry of Galicia for years through the direct control of the larger producing and refining interests and by reason of the fact that the smaller scattered interests were dependent almost entirely on the two leading companies, the Galizische Karpathen Petroleum A. G. (controlled by Society Gaz), and the Premier Oil & Pipe Line Co. (controlled by the Deutsche Erdoel A. G., which is in turn controlled by the Diskonto und Bleichroeder, a branch of the Deutche Bank) for their transportation and refining facilities. British and Dutch capital were involved in the Galician fields prior to the war, but not, it is believed, to a controlling extent in either of the dominant companies.

The petroleum industry of Japan is controlled wholly by Japanese interests and to a preponderant extent by a single company, the Nippon Oil Co. So far as the author is aware, no foreign interests share in any way in the development or control of the Japanese petroleum industry.

Commercial control of the petroleum industry of Peru is exercised by the Standard Oil Co. of New Jersey through its subsidiary, the Imperial Oil Co. of Canada. This control involves about 70 per cent. of the annual production, the remaining 30 per cent. being divided in the ratio of 27 to 3 between British and Italian interests respectively. So far as is known no other interests are involved.

The interests engaged in the petroleum industry of Trinidad include financial groups purely British, controlling about 57 per cent. of the production; British-Dutch interests (Dutch-Shell) controlling about 23 per cent., and United States interests (General Asphalt Co.), controlling the remainder. The leading operator in Trinidad is the Trinidad Leaseholds, Ltd., a British company that in 1917 produced about 42 per cent. of the petroleum output credited to Trinidad that year.

Commercial control of the petroleum resources of lower Alsace has been in the hands of the Vereinigte Pechelbronner Oelbergwerke Gesellschaft and the Deutsche Tiefbohr A. G. Both of these companies are believed to be controlled by the Deutsche Bank through the Deutsche Erdoel A. G., and the Diskonto und Bleichroeder. The negligible production of petroleum in Hanover is doubtless under the same financial control, although data that would warrant a positive statement to that effect are not at hand.

The petroleum reserves of Argentina, which comprise the only areas from which petroleum is being commercially produced in that country, are operated by the state through the Comodora Rivadavia Petroleum Commission. German interests are thought to have been involved in two or three unsuccessful efforts in the last decade to obtain petroleum on tracts adjacent to the government reserves in the Comodora Rivadavia district.

The petroleum industry in Egypt is controlled wholly by British-Dutch capital operating as the Anglo-Egyptian Oilfields, Ltd., a subsidiary of the Royal Dutch-Shell Syndicate, through the Anglo-Saxon Petroleum Co., the last-named company being predominantly British.

Commercial control of the petroleum industry in Canada is exercised in effect by the Standard Oil Co. of New Jersey, through its subsidiary the Imperial Oil Co. of Canada. This control is exercised through a virtual monopoly of pipe-line and refining facilities, and by the producing interests, though British and Canadian, being individually small and unorganized.

The production of petroleum in Italy, which is small, represents the output of two companies, the Petroli d’Italia, in which French capital is predominant, and the Petrolifera Italiana, which is believed to be essentially Italian.

Financial groups interested in petroleum in Venezuela include the Royal Dutch-Shell Syndicate (British-Dutch), the General Asphalt Co., (United States), and a group of British financiers who control properties in Trinidad as well as the most important group of companies, other than Nobels and the Dutch-Shell, in Russia.

United States interests, including the Standard Oil Co., the Doherty interests, the Texas Co., the Gulf Corporation, and the Island Oil Transport Corporation, are predominant in the quest for petroleum in Colombia. The Venezuelan Oil Concessions, Ltd., an English company operating in Venezuela, is reported to have obtained a concession to explore for oil in the northwest district of British Guiana.

The Sinclair interests (United States) are particularly active in the search for petroleum in Costa Rica and Panama; and the Sun Co. (United States) is understood to be investigating petroleum possibilities in other Central American republics.

The Pearson interests (British) have expended considerable effort in the quest of petroleum in Algeria and Morocco, and in the former country American interests (E. E. Smith) are reported to have recently sought petroleum concessions from the French government.

British interests, including the British government, control extensive petroleum concessions in Persia, from which oil in unreported quantities is now being produced.

The most promising oil territory of Persia has recently been closed to American activity through the granting of a concession aggregating approximately 500,000 square miles to a British concern, the Anglo-Persian Oil Co., a majority of whose voting stock is owned by the British government. This concession runs until 1961. The importance of the oil territory is indicated by its reported potential capacity of 30,000,000 barrels yearly, with tremendous reserves undeveloped.

United States interests (Standard Oil Co. of New York) are understood to still retain control over the petroleum rights in certain provinces in China, where active prospecting in two or three localities a few years ago was reported to have yielded unfavorable results.

Petroleum in small quantities is produced in New Zealand by purely British interests.

—As regards probable developments in the petroleum industry within the next decade, the United States, thanks to the enterprise and foresightedness of financial interests of domestic origin, seems to have a strong position. United States interests are practically supreme in the commercial control of the petroleum resources of the Western Hemisphere, dominating the petroleum industry in the United States, Canada, Mexico, and Peru, holding substantial interests in Trinidad and Venezuela and in the prospective petroliferous areas in Central America and Colombia. Its only competitors are British and British-Dutch interests, which control the petroleum situation in Trinidad and are not only strongly intrenched in the United States, Mexico, and Venezuela, but are aggressively seeking to enlarge their holdings in those countries and to gain footholds elsewhere. Unless the United States adopts measures, such as Federal operation of the trunk pipe-lines, to limit the aggressions of foreign capital in this country, and erects a firm forward-looking governmental policy toward the protection of investments of its citizens in petroleum properties in other countries, particularly Latin-American countries, it may witness its commercial supremacy in petroleum affairs wane and disappear, while it is yet the largest political contributor to the world’s supply of petroleum.

As contrasted with the strongly nationalistic and deliberately aggressive governmental policy adopted by Great Britain, France, Holland and some other nations, the United States has never adopted any policy founded on recognition of the importance of political and commercial control of petroleum. American companies may not own and operate oil lands in the British Empire, in the French possessions, or the Dutch colonies, but the only American restrictions on foreign activity in the petroleum industry are those which cover all minerals contained in public lands. Only American citizens, or those who have declared their intention of becoming American citizens, can apply for patents to such land. However, after the application is made, there is no restriction on transfer of the mineral rights thus secured.

—British and British-Dutch interests easily dominate the petroleum situation in the Eastern Hemisphere by supremacy in the petroleum industries of Russia, Persia, India, and the Netherlands East Indies. Domination of the petroleum situation in Russia alone is believed tantamount to dominion of the petroleum situation in the entire Eastern Hemisphere for the greater part of the next century. The strength of Great Britain’s present position in the world’s petroleum affairs lies in a strong governmental policy and in the wide scope of British petroleum investments, embracing practically every country where petroleum is an important product and nearly every country where it is a product of potential importance. The general policy of the British Empire seems to be to control all oil development and restrict operations by foreign capital. In Australia licenses are required for the exploitation of oil lands, and only companies incorporated in the United Kingdom or a British possession may receive such licenses. The Governor General has the right of pre-emption of all oil produced and in case of war may take control of all oil properties. In Canada, in those western provinces where minerals are the property of the Crown, petroleum and natural gas lands may be leased only to British companies. A similar restriction exists in Burma. In Burma a monopoly of the petroleum industry for 99 years was granted to the Burma Oil Co. in 1865. This grant seems to have been inspired by fear of the Standard Oil Co. of the United States, for the agreement between the company and the government stipulates that the former shall not amalgamate with other oil companies. Regulations of like effect exist in other British colonies where oil exists; in Barbados the British government has the right of pre-emption of all oil residues; in British Guiana, non-British companies can only hold lands by special license of the Governor; in British Honduras all mineral oil is reserved to the Crown; in southern Nigeria, the Gold Coast, Trinidad, and Tobago the British government has the right of pre-emption over all petroleum.

The recent granting of a concession amounting to a monopoly in the most promising oil district of Persia (a region that many oil experts believe likely to become one of the most important in the world) to a British company controlled directly (by stock ownership) by the British government, signifies an aggressive policy of England, outside of her own dominions, to secure and hold, under government control, oil lands in all parts of the globe.

It is understood that the best-known oil territories in Venezuela are already covered by concessions that are practically all controlled either directly or indirectly by British interests, chiefly the Dutch-Shell Syndicate.

So far as observed, German interests actually dominate the petroleum industry in Galicia and at home. Whether forced back on its own petroleum resources or on these reinforced by those of Galicia, Germany will obviously have an inadequate supply, and in consequence German interests are likely to be particularly aggressive in seeking petroleum in Mesopotamia, Africa and South America.

—Since control of the petroleum interests of the Rothschilds passed into the hands of the Royal Dutch-Shell Syndicate (British-Dutch), the influence of French finances in petroleum affairs has been negligible, outside Galicia and Italy, where its potency was not great. French capital will undoubtedly participate in efforts to determine the petroleum reserve of the Barbary States, French dependencies, but it will hardly be much involved in organized efforts to control the world situation with respect to petroleum.

The French mining law holds that oil and gas belong to the state, and may be exploited under concessions, the area and time limit of which are matters of negotiations between the applicant and the authorities. It is understood that the French government is unwilling to grant oil concessions except to companies the majority of whose stock is held by French citizens. A company incorporated recently to work the Algerian oil fields contains in its articles of incorporation the provision that 60 per cent. of its stock must be held by French citizens.

—Japanese investments in the world’s petroleum industry have not yet attained significant proportions outside Japan itself, though the Japanese government is officially alive to the importance of Japanese investments in petroleum properties in Mexico, particularly Lower California and Sonora; China; and undoubtedly Russia. Hence large investments of Japanese capital in the petroleum industry in one or all of those countries may be expected in the near future.

Petroleum in its crude or semi-refined state is used as fuel under locomotive and marine boilers and as a lubricant. The principal use of petroleum, however, is in the manufacture of numerous refined products. Some of the more important products and their uses are as follows: ether, as an anæsthetic in surgery; gasoline, as fuel in internal-combustion engines; naphthas, as solvents and in the manufacture of commercial gasoline; kerosene, as an illuminant and as a fuel for farm tractors; lubricating oils; waxes, as preservatives, illuminants, and surgical dressings in treatment of burns; petroleum coke, in metallurgical processes and in the manufacture of battery carbons and arc-light pencils; heavy fuel oils; road oils; artificial asphalts, for pavements. The use of petroleum and its products as fuel, as a lubricant, and for illumination may be considered essential. Substitutes for most of these uses are known, but they are either inefficient or not readily available.

The most prolific sources of petroleum are in sedimentary strata of the Carboniferous and Tertiary periods. Because the most detailed geologic work is insufficient to provide for the appropriate evaluation of the numerous factors involved in the occurrence of petroleum, and because only a relatively small percentage of the areas of sedimentary rocks throughout the world have been examined geologically in any appreciable detail, it is difficult to estimate the future supply of petroleum or to predict that large accumulations will be discovered in any particular region.

The principal countries contributing to the world’s production of petroleum rank as follows in general order of importance: United States, Russia, Mexico, Dutch East Indies, Roumania, India, Persia and Galicia. Other countries produce less than 2 per cent. of the annual total. The greatest change that is likely to come in the geographical distribution of production is a larger output from the countries bordering the Caribbean Sea and the Gulf of Mexico, and from the Persian and Mesopotamian fields. Mexico now ranks second to the United States, and South American countries promise to become more important contributors to the world’s production than they now are. Russia is expected to become ultimately one of the chief producers of petroleum.

Within the next decade, through improved methods of production and through the further amalgamation of producing, transporting, refining, and marketing companies into strong units, the output will undoubtedly be larger and will be more economically produced. In the refining of petroleum it is probable that improved methods will make possible the recovery of a larger percentage of lighter products from low-grade petroleum. Internal-combustion engines are being modified so as to run on petroleum products of lower volatility than gasoline. The use of petroleum as fuel under railroad and marine boilers is expected to increase enormously in the next decade. As the output of the producing fields declines, the vast deposits of oil shale in the western United States will be developed as a source of oil.

So far as is known, political control of the petroleum resources of the world is determined by state sovereignty (see Plate I, page 7). In normal times, the United States controls politically over 66 per cent. of the present output of petroleum. Russia and Mexico ranked second and third in 1917, controlling 13.6 per cent. and 10.9 per cent., respectively. The remaining 9 per cent. was controlled by Great Britain, Holland, Persia (British government owned), Roumania, Austria-Hungary, Japan, Peru, Germany, Argentina and Italy in the order named.

The table showing the nationality and the approximate extent of the commercial control exercised by the dominant interests in each of the principal oil-producing countries, and Fig. 2 (page 12) are the best possible summaries of commercial control. United States capital is supreme in the commercial control of the petroleum industry of the Western Hemisphere. British and British-Dutch interests easily dominate the petroleum situation in the Eastern Hemisphere. France no longer exercises control over any important fields. Japanese interests, controlling at present all the oil fields of Japan, may be expected to make large investments in the petroleum fields of Mexico, China and Russia.

Coal is among the most important of all minerals. It furnishes power and heat, and its distillation yields a great number of useful materials, such as gas for lighting and fuel, explosives, ammonia, aniline dyes, etc. Coke, which is bituminous coal with the more volatile constituents removed by distillation, is used for smelting metallic ores; and thus the contiguity of fields of high-grade coking coal and of iron ore determined the location of the centers of steel industry, which are the very main-springs of our modern machine-made civilization. Near such coal districts, other manufactures of all kinds naturally developed, the coal being cheaply available for power and constituting practically the only source of power in regions where cheap hydro-electric power is not available. About 66 per cent. of the coal mined goes to the production of power, including transportation; about 12 per cent. to coking and the by-products; and about 22 per cent. to the heating of buildings.

Commercial coal is of three varieties: (1) anthracite (Pennsylvania anthracite is popularly termed hard coal), and semi-anthracite containing a high percentage of fixed carbon and a relatively low percentage of the volatile constituents (3 to 12 per cent.); (2) bituminous (ambiguously termed “soft coal” in the United States), containing less fixed carbon and more volatile matter (12 to 40 per cent.); and (3) lignite, containing a still smaller proportion of fixed carbon and a large proportion of water. Of the bituminous coals, some coke satisfactorily, but many do not, so that good coking coals are highly prized. Anthracite, because it makes no smoke, is in great demand for house heating; whereas bituminous coal is chiefly used for power production, including locomotive and steamship firing. Lignites as a rule are used only where the better grades of coal are not available.

Coal was first used for heating before steam power came into use, and iron was smelted with charcoal instead of with coke as at present.

Ship bunkering calls for the best grades of bituminous coal, low in ash and preferably high in fixed carbon, because the use of low-grade coals would require carrying larger amounts, leaving less space for cargo. However, no country that has enough coal to bunker ships, need be dependent on foreign supplies; the low grade of coal would simply reduce efficiency and thus increase expense.

—The proportion of coal used for power, as distinct from that used for heat and coal products, is increasing, and is now two-thirds of the total. As a source of power there is really no complete substitute for coal. All the great industrial nations, like England, Germany and the United States, have developed their industries on the basis of large coal supplies. Some countries make large use of hydro-electric power, but for most it is an insufficient substitute. Wood and other fuels are rarely sufficient to maintain an industry built up on a supply of coal. Oil is being successfully substituted in some industries, notably in shipping, but the importance of coaling stations will no doubt persist.

The technique of coal mining in many districts, and the development of heat, power and coal products are not far advanced. Wasteful methods are used, mostly as a result of competition and lack of co-operation and organization among producers. Economies are being advocated, however. Labor-saving machinery has been installed in many mines. A number of power plants have been erected near the mine mouth and the power distributed electrically, thus eliminating freight charges on coal. Central heating and power plants that can burn coal efficiently will no doubt be more popular and numerous in a few years. Government control and legislation may be expected to hasten the changes. In Europe the technique of coal mining, except in undercutting machinery, is further advanced than in the United States, as regards mining all the coal and in supporting the surface.

Improvements in coking ovens may soon make possible the manufacture of some sort of coke from almost any bituminous coal. While all coke may not be satisfactory for modern blast-furnace practice, any future lack of coke will probably be offset by the development of electric smelting, so the seriousness of the metallurgical need is doubtful. The proportion of by-product coke ovens, which make for cheaper coke by providing for other marketable products, is increasing.

Coals are found in the sedimentary deposits of several geological eras: Paleozoic, Mesozoic, and Tertiary. The Paleozoic era, embracing the Carboniferous period, is by far the most important as regards quality and availability of its coal resources; but the lower-grade and chiefly lignitic coals of the Mesozoic and Tertiary are of great importance locally, and there are enormous reserves that exceed in quantity the generally higher-grade coals of the earlier periods.

The geologic distribution of coal is described in “The Coal Resources of the World,” the most important and comprehensive compilation on coal reserves ever made, which was undertaken by the Executive Committee of the Twelfth International Geologic Congress, held in Canada in 1913. As the compilation was made with the assistance of geological surveys and mining geologists of the several countries of the world, it is cited in this paper as authoritative on geologic distribution and resources.

The geographic distribution of the chief coal fields of the world is shown in Plate II.

In North America the most important coals in the Central and Eastern part are of Paleozoic age, but in the Rocky Mountain region vast quantities of coal occur in the Cretaceous (Mesozoic) strata. In the Gulf province and in the Northern Great Plains province of the United States, which extends into Canada, are coals of Triassic (Mesozoic) age that are relatively unimportant at present.

In beds of the Eocene period of the Tertiary era are large deposits of brown lignite locally converted by mountain-building forces into bituminous and semi-bituminous coal, and also a little anthracite under difficult mining conditions. Such locally altered beds are found in the State of Washington, in British Columbia, and in Alaska.

The limited coal resources of South America, in those deposits east of the Andes and in southern and eastern Brazil, are of Paleozoic age. Small areas of Tertiary coals are found in southern Argentina and in Chile.

Plate II.—Geographical distribution of the coal deposits of the world, and relative reserves. By F. F. Grout.

In Europe the principal coal deposits occur in the Carboniferous system, either in the upper or the lower part. The Lower Carboniferous is the principal series in which coals occur in Scotland, whereas the most important coals in England and in Wales lie in Upper Carboniferous rocks. In northern France, in Belgium, and in Westphalia, Germany, the middle Carboniferous measures contain the most important reserves. Mesozoic coals are found in northern Australia and in central France. The lignites or brown coals of middle Europe are locally very important in Germany; those of Austria are found in numerous small but thick deposits of the Tertiary age.

Fig. 3.—Coal output of the chief coal-producing countries, 1880-1916.

The principal coal resources of Africa are in the southern part of the continent and are chiefly in deposits whose ages range from Carboniferous to Triassic.

In Asia the coal fields are not well defined. There are coal basins of note in India and China. In China important coals are found in the Upper Carboniferous. Coals of the Lower Carboniferous are found east of the Urals and also in Turkestan. In Japan the Mesozoic coals are important. Tertiary coals are widely distributed in Asia but are not high-grade nor of importance.

It may be safely stated that geological reconnoissance has covered the world so well that further development is not likely to disclose coal resources of great magnitude not now known with more or less exactitude. Estimates of resources of some regions will undoubtedly be revised many times, especially those of reserves in the middle portion of Africa, in South America, and China.

As the great World War began on July 31, 1914, the last normal production figures were for 1913. The following table of the world’s production of coal for the years 1911-1914 is from “Mineral Resources” of the U. S. Geological Survey, the compilation being credited by Mr. Lesher, of the Survey, to Mr. Wm. G. Gray, statistician of the American Iron and Steel Institute, and Prof. G. A. Roush, editor of “Mineral Industry.”

The output (1880-1916) of the chief coal-producing countries of the world is shown graphically in Figure 3.

Table 4.—The World’s Production of Coal (in Short Tons)

Table 5.—Reserves

Total coal reserves in millions of metric tons have been estimated, by continents, as follows:

The countries on pre-war basis having the greatest reserves are as follows:

Fig. 4.—Coal reserves of chief producing countries, according to “Coal Resources of the World,” in millions of metric tons. Squares are to scale: lines showing relative production are not on same scale as squares.

The reserves of the principal productive coal fields are graphically shown in Figure 4.

The distribution of the coal deposits of the world and the estimated reserves in these deposits are shown in Plate II.

The districts with coal for export have been chiefly the British Isles, United States and Germany; there might be included also New South Wales, British South Africa, Japan, French Indo-China, Canada, New Zealand and Spitzbergen. China, with her large reserves, may become an exporter in the future; or, if her industries develop, may find use for her coal at home.

Anthracite of good grade is found in large amounts in Pennsylvania and South Wales only. Poorer supplies are known in Germany, France, Italy, Indo-China, and also in the states of Colorado and New Mexico.

Coking coals in large amounts are found in the eastern United States, Germany and the United Kingdom and are coked extensively. Smaller amounts of coke are made in France, Belgium and old Austria. Relatively very small amounts are made in Canada, Chile, New South Wales, Japan and Spain.

The coal reserve of a country bears no direct relation to its present production, for the latter, which has to be developed in competition with other countries, depends upon relative facility of transportation and proximity of iron-ore deposits, which render steel making and other industries economically feasible.

Great Britain is particularly favored through the possession of high-grade coal immediately adjacent to coast ports, as in the North of England, Scotland and Wales. Hence Great Britain became a great exporter of coal. First, coal for heating purposes traveled by sea from Newcastle to London; next coal was carried to European ports, and finally to all parts of the world. The possession of easily worked iron deposits in the north of England and the discovery that iron could be smelted with coke rapidly accelerated the development of the coal industry in Great Britain, so that by the middle of the nineteenth century Great Britain had a commanding lead.

No other country possesses high-grade coal in such quantity immediately adjacent to the coast, and this fact has enabled Great Britain to remain the great exporter. The average length of haul of export coal, from mine to ship, is less than 20 miles. In Germany coal for ocean export must be hauled 118 miles to 168 miles; in the United States from 150 to 375 miles, except for Washington coals, which are within 40 miles of tidewater, but are small in quantity and of indifferent quality.

After the war with France in 1871, when Germany annexed Alsace and Lorraine, the coal industry of the German Empire developed with tremendous rapidity, largely through the discovery—from the investigations of Thomas, of Great Britain—of a method of utilizing the high-phosphorus iron ores of German and French Lorraine, and the nearness of these iron-ore deposits to the high-grade bituminous coals of Westphalia. The coal industry was also developed by fostering the export trade with adjacent countries, which have small coal resources or none, this trade nearly all going by rail.

However, the long rail haul and the correspondingly high cost of mining have retarded the ocean export business of Germany, in spite of the fostering care of the government. With the transfer of practically all its iron deposits and its important Lorraine potash deposits, as well as the ownership of its Saar coal mines, to France, and the possible loss of its Upper Silesian coal and zinc deposits to Poland, the balance of commercial prosperity, as well, may be handed over.

No other countries except the United States, Canada, Australia and China have reserves for extensive export trade. In Canada the coals are mostly inland, and those near the coast, as on Vancouver Island and in Nova Scotia, are limited in quantity and difficult to mine, so that export business is perforce restricted.

One change that seems likely is a rapid increase in output of coal in China. The resources are enormous, the reserves of the higher classes of coal being surpassed by those of no country but the United States. The ambitious and aggressive Japanese, with their strategic neighboring location, have given every indication that they will take advantage of an opportunity to develop such a resource. It may be a question how soon Chinese coal will be developed, but great changes are inevitable when development begins. Some of the coal fields are so near the coast and have coals of such good quality as to permit an extensive development of export business in the Orient.

Australia, particularly in Queensland and New South Wales, has coal resources that are considerable, in comparison with the needs of the small population. In New South Wales the coals are excellent and are adjacent or close to harbors, so that the coal is extensively supplied for bunkerage and export trade to the South Pacific and has become a large factor in the ocean trade of that part of the world.

A large factor in the coal trade of the Pacific Ocean is the carrying of coal as return cargo. This is also important in South American trade. South Africa during the war sent considerable coal to the western Mediterranean, but its coal cannot be a large factor in ocean trade in normal times.

Of all the continents South America is the poorest in coal resources. There is coal in Brazil and Chile and other South American countries, but it is difficult to reach and the fields so far known do not give promise of being able to take care of the needs of the countries in which they occur. The total annual production of South America is less than two million tons, mostly from Chile. It is probable that for the next generation South America will continue to import coal as it has in the past, to the extent of 15 million tons or more per annum, although developments in Brazil are now promising for that country’s future supply. For estimates of reserves, see Table 5.

—By way of summary, it may be said that the United States leads the world in coal resources; moreover, its resources are most immediately available, because of their shallow depth and general undisturbed (geologic) condition and their accessibility through railway systems. This is particularly true in the Appalachian region, which contains by far the best coal, is the nearest to the coast, and hence is the most available for ocean trade. On the other hand, the average haul to export points, as already noted, is far greater than that of Great Britain and greater than that of Westphalia; but to offset this the coal has been and can be mined more cheaply than in either Westphalia or Great Britain. The resources of Upper Silesia are large, and the coal is easily mined, but the output will all be needed for central Europe. As regards both quality and quantity, Pennsylvania anthracite is unique; nevertheless, the home needs will continue to be a brake on extensive exports. United States steam and coking coals available for shipment average a little poorer than the corresponding coals of Great Britain, but are superior to the German coals.

The total resources of Great Britain, possible, actual, and probable, are only 190,000 million tons, as contrasted with 423,000 million tons in the old German Empire and 3,838,000 million tons in the United States.

—The possible depletion of coal resources is of course important in considering the future, but it can be safely stated that in none of the principal fields now being mined are the resources so depleted that the output therefrom will be reduced for another generation at least.

Of the great coal-producing countries, Great Britain, with its increasing rate of production, most nearly approaches the point of ultimate depletion, but that point has been variously placed at one hundred to several hundred years in the future, much depending upon whether with better methods of use the output will continue to increase at the same rate as in the past. Meantime, certain areas in Great Britain with shallower coal beds will be depleted much sooner and the remaining coal will become more and more difficult to get, because of the increasing depth of mining, which in turn will cause a continually increasing cost.

Although the exhaustion of coal is a distant prospect, there are clear signs of the approaching exhaustion of certain grades of coal. It has been estimated that the output of American anthracite will seriously decline in 60 to 100 years. Probably this will result in a change in practice, the use of coke, and other methods of house heating. If the rate of production continues to increase, high-grade American steam coal, New River and similar grades, will probably be exhausted in a little over 150 years. American coking coal of the best Connellsville quality is of equally short duration. British coal of similar high grade may last longer than American, as the production rate is less rapid, even though the total American coal should last much longer than the British.

In several countries state ownership of coal mines is established; as, for example, in parts of Prussia, Australia, Chile and Bulgaria. In others the undeveloped coal lands are still largely owned by the government, as in Alaska and the western United States. In some countries the government retains control of all mineral rights, simply leasing the property and granting a mining concession. Many governments have a department or administration of mines. In every country, of course, in an emergency, the sovereign state would exercise control of coal resources as fully as was necessary. Where the state owns mines, and favors organization, as in Germany, the more drastic regulation of war time is easily effected. It is quite possible that coal may in time be generally considered a public utility.

In England a movement toward nationalization of mines, with miners as well as the government having a hand in the control, seems to be making progress.

England’s colonies excel all others in extent of coal resources. There is coal in Australia, Canada, India, New Zealand, South Africa, Rhodesia, Newfoundland, South Nigeria and British North Borneo—the total being many times greater than that in the British Isles. The colonies and possessions of France, Denmark, Portugal, United States and Japan have relatively small amounts of coal.

Coal resources, along with other raw materials, have been influenced by some trade treaties. However, no permanent advantage in commerce has been secured to any nation by a trade treaty. Nearly all such treaties are made for short periods and renewed. If not satisfactory to one party they are soon corrected. Various informal or tacit agreements might be mentioned. When shipping was scarce during the war, England and the United States divided the coal business of South America according to the requirements of ship economy. Germany made agreements to send coal to Austria-Hungary and Switzerland during the period of the war. England had agreements with France, Spain, Portugal and Italy, these agreements changing with conditions, about supplies of English coal.

Although the ownership of mines in most countries is nominally open to citizens and aliens alike, exceptions and restrictions tend to keep the control in the hands of citizens. For example, it is impossible for foreigners to control any mining company in Japan. Concessions in Holland and the Dutch colonies are limited to Dutch subjects and in Bolivia to Bolivian citizens. The legislation suggested since the outbreak of the World War may develop a similar condition in the possessions of Great Britain and those of her allies.

In peace the relations of two countries may be largely determined by the ownership of property; owners of property in a foreign country may strongly influence the policy of the two governments toward each other. In emergencies, the political and the commercial control are put to the test, and there results either a deadlock or the victory of one over the other.

An important commercial relation exercising political influence is the incorporation of companies under the laws of different countries. Mining companies in China, like the Kailan Mining Administration, organize at Hong Kong to obtain British protection and are thus subject to British control, in spite of the fact that Belgian money finances the company. Some companies organized in Japan may also own Chinese coal mines.

As relatively few regions of the world have coal in excess of their own needs, the larger number are dependent on imports. If a country with coal controls also steamship lines, it may completely control the coal situation in the importing country. England, with about half the total world’s shipping and a good supply of seaport coal, has been in a position to dominate coal exports, even to handling the excess American coal. During the last three or four years the scarcity of shipping has given increased importance to American and Japanese shipping, but the English still exert a strong influence. Their docks and storage facilities are the best, and their ships are still numerous.

Railroad shipping rights over the National Lines in Mexico give a certain amount of control over the coal industry. The National Lines are state owned and have a special agreement giving trackage rights to two companies, the American Smelting and Refining Co., and the Peñoles Company, of German ownership. Since the Mexican railway service has been disturbed, the German company has been operating with cars and engines of its own. It has many coke ovens and large coal reserves, and has been the chief competitor of the American company in Mexican metallurgy.

No patent is likely to limit coal industries, except as regards the by-products of coke. Before the war, coal-tar products were largely developed by Germans, who patented their processes in many countries, but offered no such protection to foreign inventions by patents in Germany. They limited production chiefly to their German plants, and exported about $50,000,000 worth a year.

During the war, these patents in the United States were taken over by the Alien Property Custodian, and the American industries that sprung up in consequence may be permanently protected. Other allied countries took the same steps to free themselves from German control, which has retarded the development of the by-product coke industry in non-German countries.

In Germany the large mining companies generally own the coal rights. The only government that has mined coal on a commercial scale and for commercial purposes is Germany, and even there the government production covered only a small part of the total output of the German Empire. Mines of the Saar coal field and a group of mines in the Upper Silesian field owned by the Prussian government have been the only extensive state-operated mines of the world, and now, under the terms of the Treaty of Peace, the ownership of the Saar mines will pass to France. (The details are given on p. 39).

On the other hand, the government exercised a quiet but real control over the whole German coal industry. Through its ownership of the Koenigen Louise mines it acted as a member of the Upper Silesian coal syndicate. Formerly, through its ownership of the Saar mines, it was also a member of the Westphalian coal syndicate, but whether a member or not it practically approved the syndicate operations and the fixing of prices in advance; also, it co-operated with the syndicate in hauling the latter’s coal over state-owned railway systems. In certain undeveloped coal fields in Germany, the northern extension of the Westphalian field, the Prussian government retains most of the coal rights.

The Rhenish Westphalian coal syndicate is a classic example of a great interlocking trade combination. Capitalized at $571,000, it covered an enormous capitalization of individual members. The mines have votes in proportion to production, which in turn is limited for certain periods. Prices are fixed and coal is marketed for the syndicate as a unit, but other affairs are left to the companies. The syndicate as a whole is a member of a transporting and exporting combine, and disposes of its product through a combine of coal dealers. The several minor combines interlock and are practically merged in a larger organization, the Kohlen Kontor. Thus the combination had exceptional power to study the various problems of the industry, and became very powerful. It maintains a research department and an explosion testing gallery near Dortmund. In several countries German companies through the control of advertising contracts have been able to influence the editorial policy of the leading newspapers, even during the war. Over half of the German coal mined before and during the war was syndicate coal. All of the 600 other German cartels have not been as moderate in their action and regulations as the coal syndicate. When the coal syndicate, however, at one time, found it could not supply its German market with coal, it is reported to have bought inferior British coal for its customers, so that they would not themselves get good British coal and refuse to return to the German supply.

Efforts were made by the cartel to absorb and control foreign coal trade, where political and financial reasons served to render this advisable, and therefore these efforts were out of all proportion to the intrinsic value of the trade. When it was planned to capture such a trade, the German-invented “dumping” system was used, coal being sold cheaper abroad than it could be sold or produced at home, the difference being met by export bonuses. This German dumping became so serious in some countries, as Canada, New Zealand and South Africa, that special import duties were imposed to counteract it. When desirable, the syndicate purchased collieries abroad, including even a South Yorkshire plant in England, the Heraclea collieries, in Turkey, and many mines in Australia.

In Great Britain is a powerful coal combine, the Cambria, closely allied with great shipping concerns. An important trade asset in this organization, like that in the German cartel, is a banking connection by which the combine can offer long-term credit.

Coal syndicates are mentioned in Belgium. Some sort of central organization interested in coal is known in Italy, Russia, Austria-Hungary, Sweden, Greece, Argentina, Chile, and Ecuador.

France has a modified form of ownership of coal resources: this was vested formerly in the Crown and now in the Republic. The government gives concessions for mining the mineral and charges a royalty. The mineral is not considered to be owned by the surface owner or by the original surface owner, as is the case in all other important countries. The concessions granted are liberal and for large areas. The royalty or rental is small and is now paid on the basis of so much per superficial unit of area (hectare) in the concession, but the chief returns received by the public are through a percentage of the net earnings, that is, earnings available for dividends. Under the conditions prevailing in France the system seems eminently fair, and the undertakings have been profitable both to the operators and to the country. The books of the company are open to inspection by government officials, and the annual reports are published in detail. The system virtually makes the government a partner in the business.

In Great Britain most of the coal ownership is vested in entailed estates, and the royalties are a shilling a ton and upwards.

Both private and government ownership exist in the United States. Throughout the greater part of the country the large operating companies own the coal rights, although in the anthracite district of Pennsylvania the fortunate owners of the surface, or their assigns, receive large royalties, 25 to 50 cents a ton. In the Middle West most of the operators have bought the coal rights from the surface owners. When leased, the royalty is relatively small, 2 to 6¹⁄₄ cents a ton. Operators in the Rocky Mountains generally own the coal they mine. The government has sold the coal rights, but the state school lands of Colorado and Wyoming have generally been leased at royalties of about 10 cents a ton. In Oklahoma the Five Civilized Tribes have until recently, under government control, leased their lands and coal rights at about 10 cents per ton, but these rights are now being sold.

In the State of Washington a considerable amount of the bituminous coal district now opened is owned by the Northern Pacific Railway, which secured these lands as grants when the railroad was constructed. The royalty is about 15 to 25 cents a ton.

In Alaska in the Matanuska and Bering River bituminous fields, and in the Nenana lignite field, the government has offered the coal for leasing purposes at 2 cents a ton for the first period, under restrictions providing for conservation of coal and reasonable prices to consumers. Some units have been taken up in the Matanuska and Bering River fields, but, as the measures are badly contorted and the coal beds difficult to trace, progress has been slow and production has scarcely begun. Temporarily, the Alaskan Railway Commission is working some mines at Chickaloon and Eska Creek, to obtain a supply of coal pending the development of other mines by lessees. Congress, in opening the coal lands in the Matanuska and Bering River fields for leasing, has reserved tracts of not exceeding 7,680 acres and 5,120 acres respectively for the use of the Navy.

The United States still owns large areas of coal and lignite lands in the western states. Most of these lands are remote from railroads and difficult of access, but they contain enormous reserves. At present, outside of Alaska, only one mine, the Gebo mine, Gebo, Wyoming, is leased by the government, but extension of a leasing system similar to that of Alaska has been recently effected.

In the United States the anthracite industry is well organized, and its railroad connections make it notably efficient and powerful. Bituminous coal, on the other hand, is so widely distributed on both public and private lands that no private organization has attempted to control the industry. Such control has always been opposed by Congress and the general public.

Except during the war, neither Great Britain nor the United States has attempted any control over commercial mining and the sale of coal. Each country created a fuel administration, and the coal was shipped under government instructions and paid for at prices fixed by the fuel administration. In the United States this government control has practically disappeared with the war, but in England the Coal Control has so far been continued, and the tendency is for the government to retain for the present a strong guiding hand on the various “key” industries. Certainly, in the final analysis, coal mining is a public utility and should be supervised and adjusted by the government accordingly, allowing free latitude for private initiative.

Of the important coal-producing countries, only the German Empire, more or less openly, has fostered in peace times the coal industry and to some extent controlled it. In France there was only an indirect control, through the control by the government of the concessions and taxation of revenues and through tacit knowledge of the operations of the French coal syndicate, which ostensibly at least obtains and disseminates information and conducts mine safety investigations. In the United States, Great Britain, and other countries free competition has been permitted. Free competition does not seem serious in countries like France, where the supply of coal is limited, but it has had more or less serious financial effects where the supply of coal has been very large. In Germany before the formation of the syndicates the coal mining industry had periods of overproduction and serious financial depression; and at other, rarer, periods there was great prosperity. In Great Britain there have been similar times of depression and prosperity, but generally the business has been profitable.

In the United States, except in the anthracite district, where for more than twenty years the operations have been in the hands of comparatively few companies, depression and prosperity have alternated rapidly. The statistics obtained by the census show that the average profits of the bituminous industry prior to 1917 were smaller than those of any other great industry, and this has had an unfortunate effect on the best development of the coal resources. The companies generally have had little or no surplus to develop properly in the lean years; hence they have mined only the best or thickest coal, and in short periods of great prosperity many mines not directly owned by the railroads and steel companies have been worked so as to lead to “squeezes” and great loss of coal. Moreover, these conditions have also been unfortunate for labor; in times of prosperity too many new mines were opened, because of the tremendous and easily accessible resources, and in times of depression the number of days the miners worked has been so reduced that their monthly or yearly earnings have been low enough to make their living a hard one. The average number of days worked per year from 1901 to 1915 was 213. Some system of limited control of trade combinations by the government would appear to be highly advantageous for both the operators and the miners, and should insure a steady supply of coal to the consumers and steady prices with reasonable profits.

As regards trade relations between the United States and other countries concerning fuel supplies, except for a possible agreement on non-subsidy of the coal-carrying shipping, any attempt at a general agreement on so vital a necessity as coal seems unwise, except for non-duplication of elaborate coal storage and rehandling plants in ports requiring small tonnages, and preventing ruinous competition by systematic “dumping” of surplus coal to drive a competitor out of business.

Of all the continents, South America has the smallest coal resources. Although there is coal in Brazil and Chile and other South American countries, it is difficult to reach, and the fields so far known do not give promise of being able to take care of the needs of the countries in which they occur.

—Immediately after the opening of the war in Europe, July 31, 1914, the German military forces attacked and advanced in the east through Russian Poland, promptly securing the important Dombrova field, which is an extension of the Upper Silesian coal fields. The German forces also advanced in the west through the Belgian coal fields and thence through the extension of these fields in northern France, at the same time seizing the important Briey iron-ore deposits north of Verdun.

The economic effect of these advances was of enormous importance in securing all the productive coal mines of Belgium, the most productive coal mines of Russia, and most of the coal fields of northern France. The French coal and iron mines seized produced one-half of the coal output of France (20 million tons out of 40 million tons), and 95 per cent. (20 million tons) of the output of iron ore. Necessarily under these conditions France had to rely upon England and the United States to meet the military and economic need for iron, leaning chiefly upon Great Britain for the necessary supply of coal. Great Britain during the war continued to supply coal to Italy; also to Spain and other neutral nations.

The armistice ended Germany’s occupation of the coal fields of Belgium and northern France. On the other hand, the French took charge of the important Saar coal field, and the Allies occupied German territory reaching to the Rhine and beyond the Rhine at certain bridgeheads, this occupation including the supervision of the mines in the coal and brown lignite basins near Aix-la-Chapelle and Cologne and the western margin of the Westphalian basin on the left bank of the Rhine.

The treaty of peace gives to the French the important iron resources of former German Lorraine, which together with imports from French Lorraine were the chief sources of iron ore for German iron works, and the ownership of the Saar coal mines.

The terms under which the Saar mines are transferred, and the future government of the district, are indicated in the following extracts from the treaty:

“As compensation for the destruction of the coal mines in the north of France, and as part payment towards the total reparation due from Germany for the damages resulting from the war, Germany cedes to France in full and absolute possession, with exclusive rights of exploitation, unencumbered and free from all debts and charges of any kind, the coal mines situated in the Saar basin.”

This is exclusive of that part of the Saar basin in Lorraine which belonged to France prior to 1870, and which now reverts to France with some minor rectifications of boundary. The treaty further specifies, “all the deposits of coal situated within the Saar basin will become the complete and absolute property of the French state. * * * The right of ownership of the French state will apply not only to the deposits which are free and for which concessions have not yet been granted, but also to the deposits for which concessions have already been granted, whoever may be the present proprietors, irrespective of whether they belong to the Prussian state, to the Bavarian state, to other states or bodies, to companies or to individuals. * * * The value of the property thus ceded to the French state will be determined by the Reparation Commission. * * * This value shall be credited to Germany in part payment of the amount due for reparation. It will be for Germany to indemnify the proprietors or parties concerned, whoever they may be.”

As concerns the government of the territory of the Saar, at the termination of a period of fifteen years, the population will be called upon to indicate their desires, and then, “The League of Nations shall decide on the sovereignty under which the territory is to be placed, taking into account the wishes of the inhabitants as expressed by the voting.” In the meantime, the territory will be governed by a commission of five members chosen by the Council of the League of Nations.

In addition to turning over the ownership of the mines and minerals in the Saar basin, Germany accords the following options for the delivery of coal to the undermentioned signatories of the present treaty:

Besides furnishing France with coal, “Germany undertakes to deliver to Belgium eight million tons of coal annually for ten years;” and to Italy from four and one-half to eight and one-half million tons annually; and also to Luxemburg, “a quantity of coal equal to the pre-war annual consumption of German coal in Luxemburg.”

The prices to be paid for coal under these options shall be as follows:

Germany undertakes to deliver to France during each of the three years following the coming into force of this treaty,

The price paid for coke and for the articles referred to shall be the same as the price paid by German nationals under the same conditions of shipment.

The ownership of the Saar mines is a most welcome addition to the coal resources of France; and the Saar basin, as it is capable of further development, may in the future make France more nearly self-sustaining as regards coal production.

The requirement of furnishing coal to France during the rehabilitation of the French mines wrecked by the Germans is a most equitable arrangement. Germany at first, owing to the drop in the output of the Westphalian fields, claimed not to be able to furnish coal, but this situation will no doubt right itself in time, especially as France holds the whip hand through control of the iron ores necessary for the great iron and steel plants of the Rhine district. In the meantime it is hoped Great Britain, with the assistance of the United States, will be able to supply the deficiency in the coal requirements.

The problems connected with the Russian coal fields are complicated, but at least the Dombrova coal field would seem to be in the hands of the new Poland, and this carries coal resources estimated at 2,525 million tons, with an output before the war probably exceeding 7 million metric tons per annum.

According to the terms of the peace treaty, a plebiscite will determine the political control of the Upper Silesian coal fields.

—In the ocean coal trade of the world the greatest change likely is that the United States will more largely supply South America, its coal being substituted for that of Great Britain. The ocean distance is markedly in favor of the United States, particularly on the west coast of South America by vessels passing through the Canal. With the increased shipping facilities of the United States, there is every reason to believe exports of coal to South America will be equally shared between the United States and Great Britain.

At the present time, it is evident that the British coal-mining industry is in a bad way, and publicists are expressing serious alarm at the possible loss of the greater part of the export trade and the curtailment of home industries through a great decrease in production accompanied by a rapid increase in cost.

In 1913 Great Britain produced 287,000,000 long tons, and exported 77,000,000 long tons of coal. During the war, owing to the large number of miners entering the military service, the output greatly declined, but was expected to recover rapidly with the signing of the armistice and the return of the miners. But labor unrest, resulting in strikes and absenteeism, kept the output down, and on July 16, 1919, the so-called Sankey award went into effect. This award shortened the miners’ working day from eight to seven hours, exclusive of the time taken in hoisting and lowering, but inclusive of the time taken in reaching the working place. Rates were raised so that the miner received more in a day with the seven-hour day than formerly with the eight-hour day, and the Controller raised the price of coal six shillings a ton to offset the increased cost.

Sir Richard Redland, chief inspector of mines, predicted that the output for 1919 would be 230,000,000 tons, and for 1920, 217,000,000 tons, or a reduction of 70,000,000 tons from the output of 1913. Presumably, in the course of time, by using additional shifts, Great Britain may recover its former output, though manifestly at greatly increased cost; so that unless the cost in the United States goes up correspondingly, there is every probability that this country will be able to compete successfully in export business, not only in South America, but also in Mediterranean ports.

At the present time, demands for coal are reaching the United States not only from those parts of the world, but also from Scandinavia, Switzerland, Denmark, and The Netherlands. On account of nearness, however, Great Britain should be able to take care of the fuel requirements of northern Europe.

In the Pacific, it is not probable that either the State of Washington or the Territory of Alaska will produce coal in such quantity and at such a price that the output can be a general factor in the Pacific Coast trade. The demands of Alaska, Washington, and adjoining states will absorb the local production; and California will continue to import in ballast more or less coal from Vancouver Island, British Columbia, China, Japan, New Zealand, and Australia.

The immediate changes in Asia are more likely to be in the development of mines in the interior of China and in India to supply domestic needs rather than extensive exports, although, as before stated, it is possible that China will gradually get into the Pacific Coast markets.

—The United States has the best coal reserve of any country—about 3,527,000 million out of a total world reserve of 7,900,000 million tons—and good reserves of each of the several classes of coal. For many years there will be no danger of a shortage except for anthracite, good coking coal and the highest grades of steam coal, which are now actively mined. About 600,000,000 tons a year, or nearly 40 per cent. of the annual output of the world, is mined in the United States.

In contrast with the reserves and production, the exports in 1913 were only about 12 per cent. of the exports of coal from all countries; and a large part of the American exports goes to Canada by rail. Of sea-borne coal, the United States sent out only 4 per cent. This small proportion of international trade is due to the distance of our coal from seaports, the lack of organization and related shipping organizations; and, further, to the relative independence of the United States, which, from most countries, requires only a small amount of import as a return cargo for coal-carrying ships. We use our coal at home, but the advantage of exporting a considerable quantity of coal for its effects on increasing trade relationships with other countries is now becoming evident.

Correlated with the large supply and small export of coal is the remarkable development of home industries using our own coal. From the curves of production (shown in Figure 3) it seems that within a century the United States will surpass all Europe in coal production. As our industries have kept pace with coal production, our consumption of coal is indicated roughly by the production curve. Hence it seems that the United States is likely to be a center of manufacturing and wealth; and with this will come an equally certain continual increase in population and power.

The second great world supply of coal is likely to be that of China. To be sure, European production is large, but it will be divided among several powers. The main part of the world’s power and industry for the next century is so definitely located by the coal deposits (and by associated iron in most cases) that the part the United States should take in the world’s program is clear. Every precaution should be observed to have the Chinese resources controlled by powers that will not abuse them to make the world “unsafe for democracy.”

The war opened several foreign markets, especially in South America, to United States coal. Some of these markets may be permanent, but Welsh coal is still likely to dominate sea-borne trade. The United States has coaling stations as far away as Manila and the Samoan Islands, but little coal reaches them from this country. American coal supplies our government coaling stations in Alaska; Hawaii; our home ports, both Atlantic and Pacific; Cuba; Porto Rico; Nicaraguan ports; Panama Canal ports; Mazatlan, Mexico; and some South American ports. No attempt seems to have been made to establish strategic ports around the world, such as may be needed if the present increase in American shipping is to be maintained under the American flag.

No foreign control has been influential in mining or handling coal in the United States. The ownership of coal mines by aliens has been possible, but apparently has not become important.

American coal resources are so great that no single organization, foreign or domestic, has been able to dominate the situation. The lack of a strong trade combination made it possible (in 1916) for a combination of British shippers to fix the price of bunker coal in Atlantic ports, so that the mines got even less for it than for industrial coal. This was the result of competitive bids, and the lack of organization here, but it is expected that organization will develop now.

Since the war began the development of industries based on coal tar has been remarkable. There are signs, however, of an unhealthy competition in this country, and the government should be careful that internal squabbles do not open the door for German control again.

—The British Isles have only one-fortieth of the total world’s supply of coal, but this is of better than average quality. High-grade steam coal is abundant and there is a fair supply of coking coal. The annual production, 300 million tons, is about one-fifth the world’s production, and is second only to that of the United States. England before the war exported about one-fourth of the production, overseas exports from England being six times as much as from any other country in the world. Coal has constituted about three-fourths of all English exports. The coal mines are near seaports, and ocean freight rates are low, because the demand for imports gives return cargoes to England from all parts of the world. There are large supplies of coal also in the colonies, especially India, Australia and South Africa.

The coal business and shipping of Great Britain grew up together. About one-fourth of the coal shipped goes for bunkering. In 1916 England owned 40 per cent. of the world’s shipping and exported nearly 70 per cent. of the world’s sea-borne coal. The maintenance of the shipping requires bunkering ports all around the world. Coal from Wales and British colonies was sufficient to supply them all, and they constitute by far the most strategic system that any country possesses.

England, Gibraltar, Greece, Malta, Suez, Port Said, Aden, Maskat, Colombo, Singapore, Bombay, Hong Kong, Shanghai, Sydney, Fiji Islands, Vancouver, Valparaiso, St. Lucia, Jamaica, Halifax, Newfoundland, St. Helena, Bermuda, Cape Town and Durban, and others encircle the globe. France, Japan, Holland and the United States have each a few stations, but no such comprehensive system. The German proposals of terms of peace (during the war) recognized the importance of these stations by specifying that England should give up Aden, Malta and similar ports.

Trade arrangements between Great Britain and other countries have been such as to grant “most favored nation” treatment to both parties, even with Germany, where no formal treaty was in force. The free-trade policy of England is well established, and on that basis England’s commercial growth has been very great. Studies since the war began show that Germany took advantage of the freedom in British countries and the protection at home. For example, German capital controlled some collieries in South Yorkshire, through Mr. Stinnes, one of the largest components of the German Kohlen Kontor. This organization had branches in Newcastle, Cardiff, Glasgow, Hull, and many foreign ports. The French also had purchased an English colliery before the war, the Stonehall colliery, at Lydden, near Dover.

The Australian colonies and probably others found that German financiers owned and controlled most of the mines when war broke out. It took some time to destroy this influence. Early in the war, British sentiment seemed to call for action against all such German commercial aggression, and at an Allied Economic Conference at Paris in June, 1916, plans were suggested for protection by tariff and exclusion of alien ownership in allied countries. More recently it seems that the British plan is to keep British certain key industries at all hazards and at any expense, but not to abandon free trade or in any way decrease the amount of trading done.

Commercial control of the Welsh steam-coal export trade is largely in the hands of the Cambria Coal Combine, but in the trade there are several other large combinations. The anthracite industry of England is not as well organized as that of America.

Commercial control of coal exported from Wales is largely in the hands of the large combinations of British shippers, in agreement with the Cambria. Even when the war interfered with shipping, it is estimated that two-thirds of the South American coal trade was in British control.

Many instances of British financial control of coal in countries other than British colonies have not been noted. British capital is invested in a few mines in Siberia and there are extensive holdings in China.

—The reserves of coal in Germany before the war were greater than those in England, counting possible reserves, and of fair quality. Germany formerly controlled 70 per cent. of the coal on the Continent. Austrian coal was controlled, and the coal of Spitzbergen has been claimed, though now in British and Norwegian control.

Although the most important deposits of coking coal of the Continent are in Westphalia, those of Belgium and northern France are very important to a general control of the coal situation. It cannot be assumed that these important coal fields were seized by the Germans for other reasons, or that the Germans included coal and iron by accident. In 1911 the Rhenish Westphalian Zeitung advised that French Lorraine and Luxemburg should be dominated as thoroughly as Westphalia was. In 1915 the six greatest associations of business men in Germany petitioned the Chancellor to consider the control of the coal (and iron) of northern France as a military as well as economic necessity.

The annual production of coal in Germany before the war was about one-fifth of the world’s total output, closely approaching the production of Great Britain. In the first years of the war the coal output declined somewhat. In coal exports, Germany has been second only to the British Isles, but no country exports by sea one-sixth as much as Great Britain. Before the war Germany had established some fourteen “Kohlen depots” abroad and had a large amount of shipping. These bunkering ports were taken by the Allies.

An example of German industrial penetration is furnished by the case of Kiau Chau, China. In 1899 the Shantung Eisenbahn Gesellschaft was formed in Berlin with headquarters at Tsingtao. It acquired exclusive rights for 5 years to search for minerals in a zone 10 miles each side of the railway and to acquire claims. Chinese mines were not to be allowed to adopt modern methods and compete, unless they bought German material and employed German men. The mines that were developed produced good steamship coal and good enough coke, so that a blast furnace was planned. The Germans lost their control when war broke out, and these rights have passed, under the terms of the peace treaty, to Japan. German capital that had been invested some years ago in the Chung Hsing Coal Co. was bought out in 1908.

—Before the war France was fifth in the list of world’s coal producers, but for many years needed more coal than she produced. Possibly enough coal could have been mined in France by greater developments, but to import it was cheaper. French capital was invested in some foreign coal deposits. A company of French control owned the Stonehall colliery, near Dover. Before the war a French company was one of the largest operators in Turkey and was steadily acquiring new mines. A French company owned an important colliery in the Dombrova field, now part of Poland.

France has maintained government coaling stations for shipping in Indo-China, Tahiti, Society Islands, Martinique, and Madagascar; but no attempt is made to supply them wholly with French coal, or to be independent of other coaling stations.

—Italy has a poor supply of low-grade coal, and the normal production is insignificant. Imports have been large, those from Great Britain amounting in 1914 to 10,000,000 tons.

—Russia has several important coal fields. The production was 31,000,000 tons in 1915 and 23,000,000 in 1916, so that Russia, including the province of Ukraine, has ranked fifth or sixth among the world’s producers. If the demand for coal develops under the stimulus of industrial stability, the output will all be consumed in Russia. About two-thirds of the production has been raised in the Donetz basin. Half of this is coking coal.

—Japan has on the main island, Hondo, enough coal to permit considerable exports. Supplies in Korea and Formosa are less abundant. In all Japan’s coal there is very little of good coking quality.

When the war reduced the amount of British shipping in the North Pacific, Japanese ships supplied Japanese coal to a number of new coaling stations, and the British may find it difficult to regain their former prominence in bunkering there. Japanese coal now gets as far west also as Colombo, Ceylon.

Japanese law specifies Japanese control of the policy of mining companies, though some foreign financial interests are allowed. Japan controls a part of the coal produced in China, and by presenting insistent demands is increasing her control in that country. If given a free hand, Japan is in a position to exercise industrial and military control in Asia almost as thoroughly as the United States can in America. English and Belgian interests have some Chinese coal, and thus are about the only real competition at present with Japanese control.

—Outside the United States, China has the largest coal reserves of any country in the world. The coal varies in quality and grade; some of it is excellent, but the production has reached only about 18,000,000 tons a year. Some districts export and others import coal. The country could easily be independent if there were internal means of distribution. There might even be large exports if production began in advance of other industrial development. Coking coal is available only in certain areas, mostly in the south.

The largest and best-equipped producer is the Kailan Mining Administration, operating British and Chinese properties. The ownership of the company is mostly in Belgian hands, but the incorporation is under Hong Kong law, so that the company is under British control.

The chief producers in China are:

Table 6.—Chief Producers of Coal in China

The Mining Company of Shantung, producing 400,000 tons a year, formerly owned by the Germans, is now run by the Japanese military organization. Thus only one of the large producers is under Chinese control, though many smaller mines are worked by Chinese. The Chinese law designed to prevent foreign control of this sort is not effective. It requires that the share of a mining industry held by foreigners shall not be over one-half; but if a foreign company owns half the shares and finances the Chinese half by a loan, the foreign control may be complete. There is a further control of mining, through the ownership of railways. All the larger producers must ship coal by rail, and foreign nations are allowed to finance railways. The difficulty of a government exercising adequate political and commercial control when it grants concessions in this way is evident.

General mining affairs in China are supervised by a Bureau of Mining Affairs. Any specific enterprise is controlled by a commissioner of finance in each province. It is questionable, however, whether governmental control will be strong enough to overbalance commercial and financial control, and diplomatic pressure from outside. Those companies incorporated under Hong Kong law can count on British protection. Japanese demands on China have been very insistent, and it is said that about a third of the production of the country is now controlled by Japan.

As a whole, China seems to take a small part in the control of her own coal. The opportunity for other powers to get financial, and, through that, industrial favors may be involved in the problem of financing the central government.

—As regards political control, three great national or race factors loom in the future of the coal industry and in the development of wealth and power: the European, dominated by England; the American, by the United States; and the Asiatic, by Japan. The efforts of England during the war temporarily prostrated her, and diminished the grip of her export coal and bunkering trade, but conditions late in 1919 indicated that recovery might be rapid. The immediate growth in the mining of coal for use at home, with consequent progress in steel and other industries, however, will be greatest in the United States, because of our gigantic resources. In the East, however, are indications of a development of China’s coal and the growth of attendant industries on a scale which may in time outstrip those of any country except America, and transfer the bulk of wealth and power to the two great civilizations, on either side of the Pacific—the newest, that of America, and the oldest, that of China and Japan. The war and the settlements after the war proved an unmixed benefit and opportunity to Japan, and enabled her so to strengthen herself in China and Korea that she is not only the preponderating power in the East, but may claim a sphere of influence and a wide protectorate for Asia, far more effective than the American Monroe Doctrine.

Having regard to national internal economy and external and internal effectiveness, the United States will clearly neglect the main function of government if it fails to exercise an effective supervision and regulation of the coal industry. This industry is national; every citizen has an interest in it, and a right to expect its administration for the highest benefit of all.

The uses of iron ore are so well known that their enumeration is hardly necessary. From iron ore are manufactured cast iron, wrought iron, and steel. By the addition of one or more other elements, chiefly silicon, carbon, chromium, nickel, manganese, vanadium, sulphur, and phosphorus, in quantities less than 5 per cent. and usually less than 1 per cent., various qualities, such as hardness, toughness, elasticity, durability, brittleness, density, porosity, endurance, resistance to oxidation or corrosion, malleability, and fusibility, can be controlled and given to the cast iron or steel in the desired degree.

The uses of the products of iron ore are so common that the finding of objects which do not contain some of them is difficult. Besides being used as a metal, iron enters into the manufacture of paints (especially red, yellow, and blue), chemicals of various kinds, medicines, coloring matter in glass and pottery, and in the form of specular hematite it is made into jewelry. Considerable amounts of iron ore are also consumed annually for flux in the smelting of silver, copper, lead, and other metalliferous ores.

Iron and its products are more widely used than any other metal; and the yearly production of pig iron makes up 94 to 96 per cent. of the total amount of all the metals produced in the world, and in normal times averages about 80,000,000 tons annually.

Iron ores are associated with many different classes of rocks—sedimentary, igneous, and metamorphic. Where associated with sedimentary rocks the ores may be the result of direct sedimentation or may be later replacements of sedimentary beds by magmatic or meteoric iron-bearing waters. Many iron-ore deposits associated with sedimentary rocks are formed by the enrichment of original iron-bearing beds, either by solution and transportation of iron compounds or by the removal of other associated mineral constituents.

Among those important iron-ore deposits of sedimentary origin that have undergone little or no further enrichment since deposition, except perhaps directly at the surface, are the iron ores of the Clinton type of the eastern United States, the Wabana iron ores of Newfoundland, the “minette” ores of the Lorraine district in northern France, Luxemburg, and southern Germany, the oolitic siderite beds of the Cleveland district in northern England, and the hematite ores of Minas Geraes in Brazil. The most important of the sedimentary iron ores that are the result of further enrichment since deposition are those of the Lake Superior district in the United States.

Iron ores associated with igneous rock are mostly of deep-seated origin, usually having been formed by solutions that accompanied or followed the intrusion of the rocks with which the ores are associated. These ores are of two main classes: (1) Those associated with siliceous igneous rocks; and (2) those associated with basic igneous rocks. The ores associated with siliceous igneous rocks consist either of hematite or, more commonly, magnetite. They occur in granite, syenite, and monzonite, and in gneiss derived from these by metamorphism. Many important ore deposits in different countries belong to this class, among them being the magnetite and hematite deposits of Swedish Lapland and of central Sweden, the magnetite bodies of the Adirondacks and northern New Jersey in the eastern United States, various magnetite and hematite bodies in California and elsewhere in the western United States, the mixed hematite and magnetite deposits of the south coast of Cuba, most of the iron-ore bodies of Chile, and the newly developed iron ores of Manchuria. As a class, the iron ores associated with siliceous igneous rocks rank next in importance to iron ores of sedimentary origin.

Iron-ore deposits associated with basic igneous rocks are nearly all of a distinct type known as titaniferous magnetites. These ores consist of a mixture of magnetite and ilmenite in varying proportions, and therefore carry a variable amount of titanium. Many large ore deposits of this class are found in different parts of the world, among the larger ones being certain ore bodies in Wyoming, in the Adirondack region, and elsewhere in the United States, and several deposits in Norway and in northern and southern Sweden.

An important group of iron-ore deposits has resulted from mineral replacement along the contact of sedimentary rocks with igneous intrusives. These ores usually occur in limestones not far from intrusive masses of granite, monzonite, syenite or diorite, but they may be found within the igneous rocks themselves, near the contact. They are rarely associated with the more basic igneous rocks. These ores are known as igneous contact ores, and their origin is ascribed to iron-bearing solutions that accompanied or followed the intrusion of the igneous rocks with which the ores are associated. Such ores are extremely widespread, occurring in practically every continent. Locally, extensive deposits exist, as in the Cornwall district of Pennsylvania, in the western United States and British Columbia, in Chile, and in China and Japan. Igneous contact ores have furnished only a relatively small percentage of the world’s total production of iron ore, however.

There are also widespread replacement deposits in sedimentary rocks that are not associated with igneous rocks. These are believed to be formed by ordinary meteoric waters which dissolve disseminated iron minerals from certain beds or masses of rock, and redeposit the mineral elsewhere in a more concentrated form. Such ore deposits may be roughly tabular and resemble bedded deposits, or they may be very irregular. Most deposits of this type consist of siderite which has replaced limestone, but hematite and limonite deposits formed by replacement also exist. Among the important deposits of this group are the siderite ores of Bilbao, Spain, largely altered to limonite near the surface; the siderite ore of Eisenerz, Styria; and the hematite deposits near Hartville, Wyoming. Small deposits of siderite, hematite, and limonite of this type are found in many parts of the world.

Besides the classes of iron ores already mentioned, widely distributed iron ores occur as residual products derived from the weathering of either igneous or sedimentary rocks. These ores have been formed by the concentration of iron-bearing materials originally disseminated through the rocks whose weathered products they now constitute. They are mainly in the form of limonite and occur either as large bodies of relatively pure ore or as aggregates of irregular masses of various sizes imbedded in clays. To this class belong the brown iron ores associated with clay in the Appalachian region of the United States, the limonite ores of parts of Russia, and similar ores in Korea. In this class should also be included the extensive limonite deposits derived from the weathering of serpentine which have recently been developed along the north coast of Cuba, as well as the lateritic iron-ore deposits found in many tropical countries. Limonite ores associated with clays have been smelted since early ages, owing to their accessibility and the ease with which they could be smelted by crude methods. They have, however, furnished a decidedly minor percentage of the world’s production of iron ore.

The iron ore consumed by the world has been obtained principally from the four great iron-producing countries: United States, Germany, France and Great Britain.

Other countries that yield important quantities of iron ore are, in the order of their importance: Spain, Russia, Sweden, Luxemburg, Austria-Hungary, Cuba, Newfoundland, and Algeria. The normal annual output in each one of these countries is more than one million tons. Minor amounts of iron ore are produced in many other countries.

Table 11.—Iron-Ore Output of Principal Producing Countries, 1910-1917, in Gross Tons[12]

Table 12.—Pig Iron Manufactured in Principal Countries in 1850, 1890, 1900, and 1910 to 1916, in Gross Tons[26]

More than two-fifths of the total annual output of iron ore in the world has come from the United States, and of the American production more than 80 per cent. is generally produced in the Lake Superior district. This district is, therefore, by far the most important iron-ore district in the world, producing annually more than 30 per cent. of the world’s total of iron ore.

Germany and France have been next in importance to the United States as iron ore-producing countries, about 80 per cent. of the ore mined in these two countries being obtained from the Lorraine iron fields situated on the border. The annual output of these fields, which includes also the ores of Luxemburg, has been about 25 per cent. of the world’s production. The Lorraine district and the Lake Superior district together, therefore, produce somewhat more than one-half of the total iron ore annually mined in the world.

The iron ore produced in Great Britain is obtained mainly from the Cleveland district of northern England, this district furnishing about 40 per cent. of the British total, equivalent to about 2.6 per cent. of the world’s annual production. In comparison, the Birmingham district of Alabama and the Krivoi-Rog district of southern Russia, which are next in importance to the Lorraine and Lake Superior districts, furnish about 3.5 per cent. and 3.2 per cent., respectively, of the world’s annual production.

Gross Tons

Table 11 shows the world’s production of iron ore from 1910 to 1917.

Table 12 shows the production of pig iron in 1850, 1890, 1900, and 1910 to 1916.

Table 13 shows the production and movement of iron ore and the production of pig iron for the year 1913.

—The principal iron ores of the United States are the extensive pre-Cambrian hematite deposits of the Lake Superior region; the bedded fossiliferous ores of the Clinton type of Alabama and other southern states; the magnetite deposits of New York, northern New Jersey, and southeastern Pennsylvania; the limonite ores of the eastern and southern states; and the mixed hematite and magnetite ores of the West. The United States is the largest producer of iron ore in the world, and annually yields more than two-fifths of the world’s supply. More than 80 per cent. of the output comes from the Lake Superior district and most of the remainder from Alabama, New York, and Pennsylvania. In 1917 there were mined in the United States 75,000,000 tons of iron ore, of which 63,000,000 came from the Lake Superior region, 7,000,000 from Alabama, 1,000,000 from New York, and about 500,000 each from Pennsylvania, New Jersey, Tennessee, Virginia, and Wyoming; in 1918 the total production was 69,000,000 tons, of which 60,000,000 came from the Lake Superior district, 6,000,000 from Alabama, 900,000 from New York, 500,000 from Pennsylvania, and 400,000 each from Tennessee, Virginia, New Jersey and Wyoming.

The following table shows the approximate reserves of iron ore in the principal districts of the United States:

Table 14.—Iron-Ore Reserves of the United States in Gross Tons[30]

The greatest single iron and steel industry in the United States is that of the United States Steel Corporation, which controls the following iron- and steel-producing companies: Carnegie Steel Co., Illinois Steel Co., Indiana Steel Co., American Steel & Wire Co., American Sheet & Tinplate Co., National Tube Co., The National Tube Co. of Ohio, Minnesota Steel Co., The Lorain Steel Co., Tennessee Coal, Iron & Railroad Co., and the Shelby Steel Tube Co., with a total of 124 blast furnaces, having an annual capacity of about 18,000,000 tons of pig iron. Most of the blast furnaces are in Pennsylvania, Ohio, Illinois, and Alabama.

With the United States Steel Corporation is connected the Oliver Iron Mining Co., which produces about 43 per cent. of the iron ore mined annually in the Lake Superior district, this being equivalent to nearly 37 per cent. of all the iron ore mined annually in the United States. The Tennessee Coal, Iron & Railroad Co. is the chief producer of iron ore in Alabama.

Next in importance to the United States Steel Corporation as a producer of iron and steel is the Bethlehem Steel Corporation, with its subsidiaries, the Bethlehem Steel Co., Pennsylvania Steel Co., Maryland Steel Co., Jurugua Iron Co., Spanish-American Iron Co., and Bethlehem Iron Mines Co.

The works of the Bethlehem Steel Corporation have a total pig iron-producing capacity of 3,060,000 tons annually from 23 blast furnaces. Seven of the furnaces are in South Bethlehem, Pa., seven in Steelton, Pa., four in Lebanon, Pa., three in Cornwall, Pa., and four in Sparrow’s Point, Md. The Bethlehem Steel Corporation owns large iron-ore deposits in Cuba and Chile. Most of the ore consumed in its furnaces at present comes from Cuba, from the Lake Superior district, and from Cornwall, Pa.

Third in importance of the iron- and steel-producing companies of the United States is the recently organized Midvale Steel & Ordnance Co., controlling Worth Brothers, Midvale Steel Co., Remington Arms Co., Cambria Steel Co., and others. The combined pig iron-producing capacity of the 14 blast furnaces controlled by the Midvale Steel & Ordnance Co. is 2,420,000 tons of pig iron. Three of the blast furnaces are at Coatesville, Pa., and eleven are at Johnstown, Pa. This company owns important iron-ore deposits in Cuba and in the Lake Superior district.

Four other large companies produce more than a million tons of pig iron annually, these being the Republic Iron & Steel Co., with an estimated total capacity from its 11 blast furnaces in Ohio and Alabama of 1,430,000 tons of pig iron, and of 2,500,000 tons of ore from its mines in the Lake Superior district and in Alabama; the Lackawanna Steel Co., with an annual capacity in 1918 from its nine blast furnaces at Lackawanna, N. Y., of 1,440,000 tons of pig iron; the Jones & Laughlin Co., of Pittsburgh, with a capacity of 1,920,000 tons from 11 blast furnaces; and the McKinney Steel Co., with eight furnaces in Ohio, New York, and Pennsylvania, and an annual capacity of 1,205,000 tons of pig iron. The last three companies named have extensive iron mines in the Lake Superior district.

Important iron and steel companies producing somewhat less than a million tons of pig iron annually are: the Youngstown Sheet & Tube Co., with an annual capacity of 990,000 tons of pig iron from six blast furnaces, all of which are at Youngstown, Ohio; the recently organized Steel & Tube Co. of America, having six blast furnaces in and near Chicago, with an annual pig-iron capacity of 900,000 tons; the Colorado Fuel & Iron Co., an important western iron and steel producer, which has six blast furnaces near Pueblo, Colo., with an annual capacity of 625,000 tons of pig iron, and has iron-ore mines in New Mexico, Wyoming, and Colorado; and the Schloss-Sheffield Steel & Iron Co. of Alabama, with seven blast furnaces and a pig-iron capacity of 530,000 tons. Many other plants with smaller capacity are scattered through eastern and central United States. So far as is known, practically the entire iron and steel business of the United States is in the hands of American capital.

—The “minette” ore of the German Lorraine district before the war constituted by far the largest iron-ore reserve of Germany and is the chief source of present supply. Next in importance of the German ore reserves are the brown hematites occurring north of the Harz, and third and fourth in importance, respectively, are the deposits of the Lahn and Dill districts in the Rhineland, and those of Siegerland. All of these districts are in western and southwestern Germany and all of them, except Lorraine, are in the region lying east of the Rhine in Hanover, Westphalia, Hesse-Nassau, and Rhenish Prussia.

The Lorraine district is on the French border and forms a part of the large ore field of Luxemburg and northern France. The deposits, of sedimentary origin and Jurassic age, comprise extensive beds of oolitic limonite varying in thickness up to 20 feet, interlayered with marl and limestone. Seven principal beds of ore are found within a thickness of sediments ranging from 75 to 150 feet, the most important being known as the Grey seam. The tonnage[31] of “minette” ore available in the German Lorraine district is estimated at 1,830 million[32] as compared with 300 million in Luxemburg and 2,975 million[33] in northern France. The “minette” ores average 30 to 40 per cent. in metallic iron content and 0.3 to 0.7 per cent. or more in phosphorus.

The deposits of the Salzgitter and Ilsede districts north of the Harz Mountains are beds of brown ironstone conglomerate with an average thickness of 20 to 30 feet, consisting of limonite pebbles in a clayey or calcareous cement. These deposits cover many square miles, the reserves being estimated at 248 million tons. The ores contain 30 to 40 per cent. of iron and average 0.7 to 0.8 per cent. in phosphorus.

The ores of the Lahn and Dill region are mainly red hematites, that lie in an extensive sedimentary bed. They contain about 48 per cent. of iron, 0.2 to 0.3 per cent. phosphorus, and are high in silica. The reserves are estimated at about 135 million tons.

In Siegerland the iron ores are mainly carbonate, carrying 38 to 40 per cent. metallic iron and 6 to 9 per cent. manganese. They form irregular deposits abundantly scattered through the region, the available reserves being estimated at about 100 million tons.

The total iron-ore reserves of Germany (not including those of Luxemburg) actually available have been estimated at 2,540 million tons, and the probable further reserves at 1,067 million tons. Of these amounts, however, Lorraine has by far the largest part, so that the transfer of this province to France reduces Germany’s available reserves to 28 per cent. of the pre-war figure, and her further probable reserves to one-half, altogether reducing her iron-ore resources to one-third of the former amount.

As far as is known, the German iron and steel business is in the hands of German capitalists, who, besides, have important iron-ore holdings in France, Spain, Sweden, and elsewhere. Among the important iron-ore and pig-iron producing firms in Germany are Gutehoffnungshütte, de Wendel & Co., Krupp, Gebrüder Stumm, Aschener Hütten Aktien Verein, Rombacher Hüttenwerke, Thyssen & Cie., and others. All of these firms had large ore reserves in the Lorraine district when the war began.

—The iron ores of France are divided into three distinct groups: the “minette” ores of the Briey, Longwy, Crusnes, and Nancy districts; the Silurian ores in Normandy; and the vein deposits of the eastern Pyrenees.

The “minette” ores of northern France form part of the great basin of “minette” ores of France, Luxemburg, and Germany already mentioned. In 1913 they furnished about 91 per cent. of the total production of France. The iron ores of Normandy and Brittany are of sedimentary origin and are composed of hematite or carbonate or a mixture of both. The carbonate becomes more abundant with depth. The iron-ore deposits of the eastern Pyrenees consist of both hematite and siderite and are of high grade, constituting the only considerable source of Bessemer ore in France. The iron content of the ores of Normandy and Brittany ranges from 30 per cent. to 50 per cent.; that of the Pyrenees ores from 51 per cent. to 57 per cent. The latter range includes calcined siderite.

The production of iron ore from French Lorraine was about 19,500,000 tons in 1913; that of Normandy and Brittany about 1,500,000 tons, and that of the eastern Pyrenees about 500,000, making a total production of more than 21,000,000 tons for France.

The following table shows the relative output of iron ore from the different iron fields of France and Germany during the last three normal years before the war:

Table 15.—Production of Iron Ore in France and Germany, 1911 to 1913
Metric tons

The available reserves in the different districts of the French “minette” ore field are estimated as follows:[34]

Table 16.—Ore Reserves in French “Minette” Field

The list of operating companies in France shows a considerable number of German companies among the predominating French. German or probably German companies produced in 1913 six and a half million tons of iron ore, or one-third of the whole production. In the Normandy and Brittany region two German companies made 11 per cent. of the whole production; and in the eastern Pyrenees one German company produced 20 per cent. Altogether, German capital controlled over one-third of the iron and steel industry of France in 1913. The rest seems to have been in the hands of French capital.

The most important iron-producing firms in the Lorraine field in recent years have been those of de Wendel & Co., Gutehoffnungshütte, Société des Hauts Fourneaux et Fonderies de Pont-a-Moussons, Société des Forges et Acieries de la Marine et d’Homecourt, Société Anonyme des Acieries de Longwy, Société des Acieries de Micheville, and Société des Mines d’Ammermont Dommery. The first two firms are chiefly German and have controlled lands not only in German Lorraine, but also in French Lorraine. Thus, the iron-ore lands of the Lorraine district will, even after the cessation of the territory to France, be owned largely by German-controlled firms. Politically, however, France will have control of the output.

—The iron ores mined in Great Britain come chiefly from the Cleveland Hills in Yorkshire and from Lincolnshire, Northamptonshire, Cumberland, Staffordshire, Leicestershire, Scotland, and Lancashire, in order of importance. More than one-third of the total production is derived from the Cleveland Hills. The ore from the Cleveland Hills, Lincolnshire, Northamptonshire, Leicestershire, and Scotland is bedded oolitic siderite of Middle and Lower Jurassic age; that from Cumberland and Lancashire is hematite, exceptionally low in phosphorus, found in pockets in Carboniferous and Silurian limestones; and that in Staffordshire is siderite of the “black band” and “clay band” varieties found in the Coal Measures.

The following table shows the production of iron ore in the United Kingdom in 1915:

Table 17.—Production of Iron Ore in the United Kingdom in 1915

A large part of the iron ore in Great Britain can not now be worked profitably, and much of the ore that was merchantable a few years ago could not now be worked, on account of increased cost of transportation, labor, and particularly of fuel. The actual reserves of ore of present merchantable grade are estimated at 1,300 million tons; the total reserves have been estimated by H. Louis at 39,500 million tons.[35]

In 1915 the United Kingdom produced 14,000,000 tons of iron ore. In the same year nearly 7,000,000 tons were imported, of which 4,000,000 came from Spain and between one-half and one million from Algeria and Norway each, making a total of over 20,000,000 tons smelted in the United Kingdom. The total production of pig iron was nearly 9,000,000 tons, of which nearly 7,000,000 tons were produced in England, 1,000,000 tons in Scotland, and nearly 1,000,000 tons in Wales. Ireland produces no pig iron. The iron and steel industry of Great Britain, so far as information is available, is in the hands of British subjects.

Eckel[36] reviews the British iron-ore situation as follows:

—Spain is rich in iron-ore reserves, but the iron and steel manufacturing industry has had little development. The annual production of iron ore in Spain during the last years before the war amounted to about 9,000,000 tons, of which more than 8,000,000 tons were exported. The consumption of iron ore by Spanish blast furnaces has been in the neighborhood of 800,000 tons annually.

The principal iron ores of Spain lie in the northwestern part, in the provinces of Viscaya, Oviedo, Lugo, and Santander; in the northeastern part, in the provinces of Teruel and Guadalajara; and in the southeastern part, in the provinces of Granada, Almeria, Murcia, Sevilla, and Huelva.

The iron ores of the Bilbao district of Viscaya are all of Bessemer grade, and for many years large amounts have been exported to England for use in Bessemer plants to supplement ores from the Cleveland and other districts of England. Because of their excellence, they have been in continuous demand, and the English iron and steel industry has depended to a considerable extent upon these and other high-grade ores of Spain. In more recent years, Germany has also become interested in the Bilbao iron fields, and in the last years before the war Germany took more than one-third of the total Spanish production, including large amounts of ore from southern Spain as well. Spanish interests own important deposits in southeastern Spain and in the Bilbao district.

Most of the ore of southeastern Spain is of high grade, being rich in iron and low in phosphorus. Nearly all of it is of Bessemer quality, and some is very low in phosphorus; the latter is exported extensively for use in the manufacture of low-phosphorus pig iron. The United States has been largely dependent in past years upon Spain for this grade of ore, more than 100,000 tons being imported annually.

Spain has a number of blast furnaces and steel plants, the principal ones being at Bilbao, in the Province of Viscaya. More than 300,000 tons of pig iron are produced annually in Viscaya, this being approximately three-fourths of the total output of pig iron in Spain.

—In European Russia[37] the principal deposits of iron ore are distributed over four chief districts: Ural Mountains, central Russia, southern Russia and the Caucasus.

In the Ural Mountains for the greater part the ores are associated with igneous rocks. The most important deposits are in the neighborhood of Gora Blagodat, in the northern Ural regions, and near Gora Mongnitnaja, in the southern Urals. The ores are mainly magnetite and limonite and come from an extremely large number of small mines. In central Russia, over widely scattered areas, are deposits of calcareous ores, clay ironstones, and bog ores. Many of the deposits are thin and can not be profitably worked. The only reserves in southern Russia of any importance are divided among three centers: Krivoi-Rog, the Donetz basin, and the Kertsch peninsula. By far the most important deposits are the magnetite-hematite ores in the region of Krivoi-Rog. The ironstones of the Coal Measures in the Donetz basin and the limonite of the Kertsch peninsula are of secondary importance. The mines of Krivoi-Rog are extensively worked, and their reserves are estimated at some 86 million tons of commercial ore. The mines are controlled mainly by the following three companies: the Briansk company; Krivoi-Rog Iron Ore Co.; and the Providence company.

The following table shows the production of iron ore in different parts of Russia in 1912:

Table 18.—Output of Iron Ore in Russia

The ore reserves of Russia may be summarized by districts as follows:

Iron-Ore Reserves in Russia

Eckel[38] reviews the iron-ore situation in Russia as follows:

Actual available ore reserves of merchantable grade in Russia are estimated at 865 million tons.

Before the Revolution the greater part of the Russian iron and steel industries was controlled by syndicates.[39] The oldest of these consisted of manufacturers of medium sheets (1902); then followed manufacturers of joists and U-iron (1903), axles and tires (1904), iron tubes (1906), rails (1907), and bar iron and hoops. These six syndicates were afterwards combined into one, officially styled the Association for the Sale of Products of the Metallurgical Works of Russia, but generally known as “Prodameta,” from its telegraphic address. There were separate syndicates for wire, wire nails, and roofing sheets. The “Prodameta” consisted, at last advices, of nineteen works, of which sixteen are in southern Russia, and one each in Petrograd, Moscow, and the Ural region. The “Prodameta” expired at the end of 1915, but was provisionally prolonged for one year, and again at the end of 1916 it was extended for a similar period. The aggregate capital of the eighteen works was 198,400,000 roubles, and their net profit for 1915-16 was 76,200,000 roubles.

—The iron-ore fields of Sweden are among the most important in Europe and have for the last ten or fifteen years furnished a large output, which has gone mainly to England and Germany. A relatively small amount of iron ore is used in Swedish iron-smelting works. The iron mines of central Sweden have been actively worked since about the beginning of the twelfth century, whereas those of Swedish Lapland have been developed recently. At present about one-half the output of iron ore in Sweden comes from Swedish Lapland, and the other half from central Sweden.

Swedish Lapland is estimated to have iron-ore reserves amounting to 1,128 million tons. The ores are mostly magnetite associated with igneous rocks and show wide difference in phosphorus content. Certain deposits or parts of deposits are composed of ores that are moderately low in phosphorus, whereas others are high enough to obtain a special bonus from German steel plants that produce high-phosphorus slag for fertilizer purposes. Practically all the ores of Swedish Lapland are exported. In recent years the total production has amounted to about 3,500,000 tons annually. The principal mines are worked by the Trafikaktiebolaget Grängesberg Oxelosund, in which English and German capital is interested with the Swedish government. The Swedish government controls the output of the mines and receives a large sum in royalties on the ore produced. The ore deposits from which ore is being produced at present are Kiruna, Gellivare, and Tuolluvarra, the first two being operated by the firm mentioned above and the last being an independent operation.

The ore reserves of central and southern Sweden are estimated at 140 million tons, included in a great number of relatively small deposits. Most of the mines of central Sweden are controlled by small Swedish operators. Some of the mines, however, such as Blotberg, are to a large extent under German control, and the largest one, Grängesberg, is operated by the same firm that controls the deposits of Swedish Lapland. Some of the ores of central Sweden, such as those of Dannemora, Norberg, Strossa, and Stripa, are very low in phosphorus, and are used in the manufacture of special low-phosphorus iron; others, like those of Grängesberg and Blotberg, contain more than 1 per cent. of phosphorus.

—The iron ores of the former Austro-Hungarian Empire are mainly low-grade hydrous iron silicates that require roasting, large deposits of iron carbonate, and some limonite. The total probable ore reserves have been estimated at 940 million tons, of which about 560 million are very low grade.

The principal sources from which the domestic iron ore used in the past in the Austro-Hungarian Empire has been obtained are the chamosite-hematite deposits at Nucitz and elsewhere in Bohemia; the siderite beds at Erzberg, in Styria, estimated to contain more than 200 million tons of ore; the siderite-limonite deposits on the slopes of the Carpathians; and deposits of various ores in northern and central Bosnia.

By far the largest of the deposits is that at Erzberg, owned and operated by the Oesterreichische Alpinen Montan Gesellschaft, presumably Austrian. The Bohemian deposits, also important, are largely under the control of the Prager Eisen Industrie Gesellschaft. The Carpathian deposits are largely controlled by local individuals and firms, among them Duke Philipp of Sachsen-Coburg-Gotha-Kohar. Thus the principal deposits have been largely under Austro-Hungarian control.

As a result of the war and the disruption of the Austro-Hungarian Empire, the Bohemian deposits, estimated to contain 35,100,000 tons of high-grade ore and 221,800,000 tons of low-grade ore, will come under the control of Czechoslovakia, whereas the Bosnian ores, with an estimated reserve of 21,500,000 tons, will go to Jugoslavia. Austria will retain control of the large Erzberg deposit in Styria, and the ores of the Carpathian region will continue under Hungarian control.

—The iron ores of Morocco, Algeria, and Tunisia, in northern Africa, are mainly high-grade hematite. The reserve tonnage of Algeria and Tunisia is estimated by Nicou at 100 million to 150 million tons, and about 30 million or 40 million tons is reported in the Spanish territory of Riff, Morocco.

The deposits of Morocco and Algeria are nearly all near the north coast, and the ores are shipped from various small ports, such as Melilla, Benisaf, Arzeu, Algiers, Bougie, and Bona. The deposits of Tunisia are 180 to 200 kilometers southwest of Tunis, the shipping port, with which they are connected by rail.

The principal mines of El Riff, Morocco, are owned by the Sociedad Española de Minas de Riff. German interests, the “Netta Company,” held a large concession, but since the war these interests are controlled by the Company of Bilbao.

The North African deposits are important as a source of high-grade low-phosphorus ore for European blast furnaces. All of the ore produced is exported, the annual shipments amounting to about 1,500,000 tons.

—There are two principal groups of iron-ore deposits in Cuba—the magnetite and hematite ore on the south coast, and the brown ore, or limonite, on the north coast. All are near the eastern end of the island. The ores of Firmeza and Daiquiri, on the south coast, are mixed magnetite and hematite, averaging about 58 per cent. iron and 0.03 per cent. phosphorus. They are associated with igneous rocks. A determination of tonnage is difficult because of the irregularity of the ore bodies, and estimates of reserves range from 5 million to 9 million tons. The brown ore of the north shore is hydrated brown hematite, a laterization product of serpentine. The dried ore averages about 46 per cent. iron, 0.01 per cent. phosphorus, and 1.7 per cent. chromium. The reserve tonnage, estimated as high as 3,000 million tons, is mainly contained in the three large deposits of Camaguey, Mayari, and Moa.

The principal deposits of Cuba are owned and operated by the Bethlehem Steel Co. Important undeveloped deposits are owned by the Buena Vista Iron Co. (Midvale Steel & Ordnance Co.), United States Steel Corporation, Guantanamo Exploration Co., and Eastern Steel Co.

—The principal iron ores of Newfoundland are bedded oolitic hematites, which average 50 per cent. to 52 per cent. in metallic iron. The ore reserves of Newfoundland have been estimated as between 3,250 million and 3,500 million tons, making them among the largest and by far the most compact iron-ore reserves in the world. The output of ore has been 1,000,000 to 1,500,000 tons annually, except during the war, when the production decreased. These deposits are important on account of both their size and their situation. Ore can be placed readily in American or European ports at a cost far lower per unit of iron than any competitive ore, so that the market is practically unlimited.

The ores have been mainly exported to Sydney, Nova Scotia, and to Philadelphia, while about 10 per cent. has gone to Holland (Germany). The phosphorus content is too high for normal economic basic open-hearth practice if the ores are used alone, but not too high for foundry use or for the basic Bessemer process developed in Europe.

The Wabana iron-ore deposits are owned and mined by the Dominion Iron & Steel Co., and the Nova Scotia Steel & Coal Co., two Canadian firms. Both companies operate steel plants near Sydney, Cape Breton.

—The principal iron ores of Norway are low-grade magnetite and specular hematite, much of which can profitably be concentrated. They occur in the northern part, north of the Arctic Circle. Small deposits of high-grade ores, consisting mainly of magnetite lenses, occur in southern Norway.

The Sydvaranger deposits, in the extreme north near the border of Finland, are estimated to contain 100 million tons of low-grade magnetite. The ore is treated in a large concentrating plant erected by a Norwegian company but controlled by Swedish and German capital. The concentrates analyze 70 per cent. iron and 0.02 per cent. phosphorus. The Dunderland deposits on Rannenfjord, near the Arctic Circle, are estimated to contain 80 million tons of mixed low-grade specular hematite and magnetite.

In 1914 Norway produced 652,273 tons of iron ore, of which seven-eighths came from the Sydvaranger deposit.

—The most important iron mines in Italy are the hematite mines of the island of Elba, which have furnished between 500,000 and 1,000,000 tons of ore annually in recent years. Ten or twelve large ore bodies are found in the eastern part of the island, all under control of the Elba Company, which has obtained a concession giving it exclusive iron-mining rights on the island. Important but as yet little developed magnetite deposits are found in the Aosta Valley, Piedmont, and limonite deposits are found on the island of Sardinia. These have furnished a very small output. Minor deposits of iron ore occur in Lombardy, in the Apennines of central Italy, and elsewhere. The total reserves of iron ore in Italy are estimated at about 25 million tons.

Italy has several important iron-smelting works, among them being the Elba Company furnaces on the island of Elba, the Piombino furnaces at Piombino, on the mainland opposite Elba, and the Ilva furnaces at Bagnoli, near Naples. In addition there are some small plants in northern Italy.

Italy’s iron-ore deposits and iron manufactures are controlled by commercial organizations, mainly Italian, but in part English. The Italian government exercises control over the ore deposits by granting concessions for comparatively short terms.

Agreements made among the Italian manufacturers for the rational division of work have led to the formation of a syndicate of the following firms: Ilva, Elba, Siderurgica di Savona, Metallurgica di Lestre, Ferriere Italiane, and the Piombino Steel Works. These firms undertook to maintain the syndicate for eleven years, dating from July, 1911. The affairs of the organization were directed by the Ilva Company. “In 1916 the constituent companies renewed their agreement up to the year 1930, but the Ilva Company ceased to direct the affairs of the Syndicate, and the relations between the Syndicate and the German Stahlwerks Verband were abrogated and replaced by Anglo-Italian relationships.”[40]

A further organization was made called the “Societa Ferro ed Acciaio,” a combination of steel works.

Italy is important as a producer of iron ore and as a manufacturer of iron products. She has been able to supply her own needs in iron ore for many years and at the present rate can continue to do so for probably twenty years longer. There appears to be no tendency toward expansion into other fields to control foreign ore deposits.

Italy produced 593,000 tons of iron ore in 1913; 669,000 tons in 1915; and 927,000 tons in 1916. In 1915, 408,000 tons of pig iron were produced, and 87,000 tons were imported.

—Chromiferous iron ores are found in eastern Greece and adjacent islands. They contain 46 to 52 per cent. iron, 2 to 3 per cent. chromium, and about 0.10 to 1.00 per cent. nickel and cobalt. The normal annual production of iron ore in Greece has been in the neighborhood of 400,000 tons.

—Small iron-ore deposits occur in New Brunswick and Nova Scotia. In Ontario there are two principal iron-ore districts—the Atikokan and the Michipicotan ranges. The ore in the former is magnetite, and in the latter hematite and siderite with some limonite. The ores of western British Columbia are largely magnetite. The principal deposits are on Texada and Vancouver islands, where the ore is of excellent grade, averaging 63 per cent. iron, 0.02 per cent. phosphorus and 4 to 10 per cent. silica. Low-grade magnetite ore is found at the Moose Mountain mine, Ontario, and is being concentrated.

There are a number of blast furnaces in Canada, among them being those of the Dominion Iron & Steel Co., Sydney; the Nova Scotia Steel & Coal Co., Sydney Mines, and the Londonderry Iron & Mining Co., Londonderry, all of which use ores from Newfoundland and Nova Scotia; the Algoma Steel Corporation, Sault Ste. Marie, Ontario; the Steel Company of Canada, Hamilton, Ontario; the Canadian Furnace Co., Port Colborne, Ontario; the Canada Iron Foundries, Midland, Ontario; the Standard Iron Co., Deseronto and Parry Sound, Ontario; and the Atikokan Iron Co., Port Arthur, Ontario, which use largely Lake ores of the United States and Canada. The Moose Mountain Co., of Sellwood, Ontario, has a magnetic concentrating and briquetting plant using ore from the Moose Mountain mine. In May, 1920, the British Empire Steel Corporation, the second largest in the world, was formed by the merger of nine steel, coal, ship-building and transportation companies.

In 1912 Canada produced 156,000 tons of iron ore, and made 906,000 tons of pig iron.[41] In 1918 she made 1,066,071 tons of pig iron. The iron mines of Canada are largely of Canadian and partly of American ownership.

—Little information is available on the extent of the iron-ore deposits of the Chinese Empire. The principal producing area is that of Tayeh, south of Yangtse River in the Province of Hupeh, where a series of ore bodies, consisting of mixed hematite and magnetite, occurs along the contact of limestone and intrusive syenite. The deposits are estimated to contain about 40 million tons of ore.[42] The Han-Yeh-Ping Iron & Steel Co., largely controlled in Japan, owns these deposits and the Han Yang steel plant near Hankow. Iron ore similar to that of Tayeh is reported to occur farther down the Yangtse at Tungling, in the Province of Ngan-whei, and also along the coast near Amoy, Province of Fukien. The deposits near Amoy are said to contain about 25 million tons.

Of considerable importance are the mixed hematite and magnetite ores of Chin-ling-chen, near Kiaochow, Shantung Province. A series of ore bodies, some of them 100 feet in width, are said to occur along a contact zone two kilometers in length.[43] The deposits were exploited by Germans and are being developed by Japanese.

Sedimentary beds of oolitic ore of some extent are reported in the provinces of Chih-li and Kiang-si, but they are of low grade.

Bedded siderite ores similar to the Coal Measures ores of England have been mined for many years in Shan-si Province and smelted in native furnaces. In Hunan Province, also, this type of ore is mined.

The principal iron ores of Manchuria are magnetites that occur as a series of deposits in a northwest-southeast belt south and southeast of Mukden, in southern Manchuria. They are interbedded with schist, gneiss, and porphyry. In this belt are the An-shan-chang deposits that are now being developed by Japanese interests affiliated with the South Manchurian Railway, and the Miaor-kow deposits operated by a Sino-Japanese company, the Pen-hsi-hu Coal & Iron Co., Ltd. The southern Manchuria magnetite belt is reported to contain reserves amounting to about 500 million tons.[44] Much of the ore is of low grade.

—Iron ores of four types are found in India[45]: (1) lenses of specular hematite with some magnetite, occurring in quartz-hematite and quartz-magnetite schist of the Dharwar series and other older rocks; (2) granules of magnetite and hematite scattered through granite and schist; (3) clay ironstones in the Coal Measures of Bengal; and (4) lateritic ores.

The hematite-magnetite lenses interlayered with iron-bearing schists are the most important of the Indian ores, although it is only recently that they have been exploited. The Tata Iron & Steel Co. owns the principal deposits of this type, including Mayurbhanj, in Bengal, where mining is being conducted at present, and the large undeveloped deposits of the Raipur district, Central Provinces. Important deposits of this type are also found in southern India.

Magnetite and hematite derived from the disintegration of schist and granite are now being used by the Bengal Iron & Steel Co., of Barakar. They consist of surface accumulations of iron sands and are found in various parts of India. Clay ironstones scattered through shales were formerly used by the Bengal Iron & Steel Co., but its supply of these is exhausted. Lateritic iron ores lying at the surface are widespread but undeveloped.

The principal iron and steel company of India is that of Tata & Sons, an Indian firm. Its plant, which has been mining since 1912, is at Sakchi, in Bengal, and comprises three blast furnaces with a total monthly capacity of 24,000 tons of pig iron. There are also extensive coke ovens, open-hearth furnaces, and steel mills. Many additions are being planned. The Bengal Iron & Steel Co., which has been in operation for thirty years, has three small blast furnaces at Barakar, with a monthly capacity of 12,000 tons. A steel mill and rolling mill built by this company have been abandoned.

Several new developments are being planned in the Indian steel industry, among them being the Indian Iron & Steel Co., an English firm, which is building a plant near Asanol on the East Indian Railway.

The production of iron ores for 1915 was 390,270 tons, the production of iron and steel for 1914 was 504,564 tons and for 1915 to 1916 it was 584,775 tons. Total imports of iron and steel, 1914 to 1915, amounted to 698,635 tons, and 1915 to 1916, to 424,597 tons.

—The iron ore used in Japanese furnaces is obtained in part from domestic mines and in part from Korean, Manchurian, and Chinese mines. The iron ore produced in Japan comes mainly from the Kamaishi group of deposits in the northern part of the island of Honshu. These mines yield more than one-half of the total annual production of iron ore in Japan, the remainder coming mainly from the Sennin and Kuriki mines, also in the northern part of Honshu; the Abuta and other bog ore deposits in Hokkaido, and the black sand deposits of Chugoku, in southern Honshu. The Kamaishi, Sennin, and Kuriki deposits consist of magnetite and hematite associated with sedimentary rocks near igneous intrusions. The iron-ore reserves of Japan are estimated by Inouye[46] at about 60 million tons.

The Korean iron ores used in Japan have come mainly from the surficial limonite deposits of Hoang-hai-do, about 100 miles northwest of Seoul, which have been actively mined for 10 years or more. Recently Japanese-controlled blast furnaces have been established at Ken-ji-pho, Korea, which use ore from the Ken-ji-pho iron mine, situated in the same region as the Hoang-hai-do mines. The pig iron produced by this plant is sent to Japan for use in Japanese steel plants.

Chinese iron ore used in Japan has been obtained from the Tayeh mines of Hupeh Province. A part of the ore from these mines goes directly to Japan, and a part goes to the Han-Yang furnaces, near Hankow, to be manufactured into pig-iron and steel products which also go to Japan. The Han-Yeh-Ping Iron & Steel Co., which owns both the Tayeh mines and the Han-Yang furnaces, is a Chinese concern, the capital of which is at present controlled largely by Japanese banking firms.

Of considerable interest at the present time is the development by Japanese of the Chin-ling-chen iron-ore deposits on the peninsula of Kiaochow, Shantung Province. These deposits were being exploited by the Germans just before the war and have recently been taken over by the Japanese, who are continuing development.

Two important Japanese-controlled iron and steel manufacturing projects are at present being developed in Manchuria. The older of these is the plant of the Pen-hsi-hu Colliery & Mining Co. at Pen-hsi-hu, southeast of Mukden, where pig iron is being manufactured from ore obtained from the neighboring Miaor-kou magnetite mines. The pig iron is being sent to Japan. The other Manchurian enterprise is the An-shan-chang iron and steel works at Sha-ho-kou, south of Mukden. The ore is derived from the An-shan-chang iron mines and the pig iron and steel products which it is later planned to manufacture are to be sent to Japan. It is also planned to send Manchurian ore to Japan.

On page 77 are shown the production and importation of iron ore into Japan in recent years:

Table 19.—Production and Importation of Iron Ore into Japan, 1914 to 1916
(Metric tons)

A considerable quantity of pig iron is imported into Japan from British India, Great Britain, and other countries.

The principal iron-smelting works in Japan are as follows: Imperial Steel Works, Yawata; Kamaishi Iron Works, Kamaishi; Wanishi Iron Works, Tanburi; Sennin Iron Works, Waka; Kuriki Iron Works, Kisen. All are controlled by Japanese, the first being the Japanese government works.

—In Poland the chief deposits of iron ore are the limonite deposits in the Vistula district, carrying 22 to 50 per cent. iron. The production in 1912 was 289,000 long tons. The resources are estimated at 300 million to 800 million tons.

—Belgium’s production of iron ore in recent years has amounted to about 150,000 tons annually, of which more than half was derived from the “minette” ore beds in the southeastern part along the French border, and the remainder came in part from beds of oolitic hematite of Devonian age in the Namur and Liege basins and in part from bog-ore deposits in the northern part. In the past the largest production has come from the Namur basin, and there are still large reserves of these oolitic hematite ores. The total iron-ore reserves of Belgium are estimated to be about 62,500,000 tons.

The iron ore produced in Belgium supplies only a very small part of the requirements for the Belgian iron and steel industry, most of the ore being imported from France.

—The largest deposits of iron ore in Portugal are those of Moncorvo, in the northeastern part. The ore is a bedded sedimentary deposit of low grade and the estimated reserve is 45 million tons. Small deposits of magnetite and brown hematite are found in the southern part in the Province of Alemtejo. Portugal produced 48,342 tons of iron ore in 1913.

—Minor deposits of magnetite and hematite occur in Bulgaria and former European Turkey, and in western Asia Minor several important ore bodies are known.[47] The largest of these deposits occurs in the Berut Hills, 90 miles northwest of the Gulf of Alexandretta. It is reported to be capable of producing 300,000 tons annually.

Other important deposits are found near Ayazmat, on the mainland opposite the island of Mitylene, and near Tireboli and Trebizond, on the Black Sea. The only producing mine is near Ayazmat.

—Scattered iron-ore deposits occur in Chile in the coastal mountain region; the principal deposits extend a distance of about 150 miles parallel to the coast, some of them being north and some south of Coquimbo. The ore bodies are within 10 to 40 miles of the coast. Most of them are enclosed as lenses in granitic rocks; a few are in sedimentary rocks near the contact of igneous rocks.

Furnaces and a steel plant were erected by a French syndicate 10 to 15 years ago in southern Chile. The plant ran only a few months, there being apparently no market for the product. The iron ore was obtained from the Tofo deposit, and green wood was used for fuel.

Of the Chilean deposits, the largest, Algarrobo, is owned by a joint Dutch-German syndicate controlled by Wm. H. Müller & Co., and Gutehoffnungshütte. Tofo, next in size to Algarrobo, is under lease to the Bethlehem Steel Co. Most of the other deposits are owned by Chileans. The tonnage of Chilean ore controlled by different nationalities is approximately as follows:

Iron ore was mined at Tofo during 1914, 1915, and 1916, and exported to the United States. In 1915 about 153,000 tons were shipped. During the war the mining practically ceased.

—The iron-ore deposits of Minas Geraes, Brazil, are among the most important in the world. The ore bodies, which as yet are practically undeveloped, lie in an area roughly 100 miles square, the center of which is 225 miles in a direct line north of Rio de Janeiro. The principal ores are hematite and are associated as beds and lenses with a laminated ferruginous quartzite known as “itabirite” that covers many square miles. The interlayered beds and lenses of ore are high grade, carrying up to 69 or 70 per cent. of metallic iron and averaging between 0.003 and 0.025 per cent. phosphorus. Nearly all ores of this type are of Bessemer or low-phosphorus grade. There are also large areas of recently formed surface ores consisting of mixed hematite and limonite moderately high in phosphorus; these average 55 to 65 per cent. in metallic iron.

On account of the distance from the coast and high cost of transportation, only the high-grade bedded ores are considered at present as available. The Central Railroad of Brazil runs through the iron-ore district to the port of Rio, 310 miles from the southern edge of the district, but unfortunately, on account of heavy grades, it can not be used for extensive transportation of iron ores. As workable bodies of coal suitable for iron manufacture are not known to exist in Brazil, the Minas Geraes deposits have up to the present produced little ore.

The principal iron-ore deposits of Minas Geraes are owned by the Itabria Iron Ore Co., the St. John del Rey Gold Mining Co., Ltd., the Brazilian Iron & Steel Co., and the Compania Metallurgica, the first two being English, the third American, and the fourth Brazilian. The Deutsch-Luxemburgisches Bergwerks und Hütten Aktiengesellschaft (German), the Société Anonyme Franco-Bresiliene (French), Jules Bernard, Mathiew Goudchaux et Cie (French), the Minas Geraes Iron Syndicate (American), and others, own local deposits. The following table shows approximately the tonnage of ore controlled by each nationality:

Table 20.—Brazilian Iron Ore Controlled by Different Nationalities

Iron ores similar to those of Minas Geraes, and magnetite deposits of minor importance are reported in other parts of Brazil.

—Mexico has important deposits of iron ore in the States of Lower California, Coahuila, Durango, Guerrero, Michoacan, and Oaxaca. The largest iron and steel making plant in Mexico is that of the Compañia de Aciero y Fierro de Monterey, State of Nuevo Leon, operated by Spanish capital. This plant produces between 50,000 and 100,000 tons of pig iron yearly. Ore is obtained from Coahuila, and coke from nearby coal fields. At Durango is a charcoal furnace, which has been idle for many years. It is owned by the Durango Iron & Steel Co. (American). Small iron-making operations exist in Hidalgo, Puebla, Vera Cruz and Oaxaca. The best known of the Mexican iron-ore deposits is that of Iron Mountain (Cerro de Mercado), near Durango City, a large body of magnetite. In Lower California there are important deposits of iron ore at several localities. They are owned by the International Development Co., an American firm with headquarters at Los Angeles, California. The deposits in Guerrero, Michoacan and Oaxaca are reported to be extensive.

—Various deposits of low-grade iron ore are found in South Africa. In Transvaal there is siliceous sedimentary hematite and magnetite in ferruginous schists of different ages, titaniferous magnetite associated with basic igneous rocks, and local clay-band ore; and in both Cape Colony and Transvaal there are lateritic surface ores. A 15-ton blast furnace has been built within the last year or two near Pretoria by the Pretoria Iron Mines Co., Ltd., for the purpose of manufacturing pig iron from local ores. This is the first attempt to establish an iron industry in South Africa.

—In Australia and New Zealand are some important iron-ore deposits, but only a few are developed. Most of the iron ore mined in Australia has been used for flux in copper, lead, zinc, and other smelting plants; a small amount has been used in the two local iron and steel works—that of the Broken Hill Proprietary Co., at Newcastle, New South Wales, and that of the Eskbank Iron Works at Lithgow, about 75 miles west of Sydney, New South Wales. The former is the more important, having in operation at the present time two blast furnaces as well as steel furnaces, rail mill, and plate mill.

Among the important Australian iron-ore deposits are the hematite ores of Coombing Park, near Carcoar, and of Cadia, near Millthorpe, both in New South Wales, estimated to contain reserves of 42 million tons of ore; the hematite deposits of the Murchison district, about 400 miles northeast of Perth, western Australia, where one single deposit—that of Wilgi Mia—has been estimated to contain more than 25 million tons; the Iron Monarch manganiferous iron-ore deposit, estimated to contain 20 million tons of ore, and the neighboring Iron Knob hematite deposit of one million tons, both about 40 miles from Port Augusta, at the head of Spencer Bay, South Australia; and the hematite deposits of Mt. Leviathan, estimated at 10 million tons, located about 250 miles from Normanton, on the Gulf of Carpentaria, Queensland. Numerous smaller and less important ore bodies are found in all the provinces.

The Coombing Park ores have been used at the Eskbank Iron Works, 90,200 tons being produced in 1916. The ore averages about 55 per cent. iron. The Iron Monarch deposit is being developed by the Broken Hills Proprietary Co., and the ore is to be used in the furnaces at Newcastle.

An important iron-ore deposit, estimated to contain 23 million tons of minable ore, is reported to occur on Blythe River, in the northwestern part of Tasmania, about 6¹⁄₂ miles from the coast. There have been rumors recently of a possible exploitation of this deposit.

In New Zealand large deposits of limonite occur in the Nelson district, in the northern part of South Island. The principal group of deposits, known as Parapara, is estimated to contain about 64 million tons. Titaniferous magnetite sands, measurable in millions of tons, are reported to occur in the southwestern part of North Island near New Plymouth.

—The world’s chief iron- and steel-producing countries are, in the order of their importance: United States, Germany, Great Britain, France, Russia, Austria-Hungary, and Belgium. The annual pig-iron production of these countries ranged in 1913 from 2,300,000 tons in Belgium to 30,900,000 tons in the United States. The normal consumption of iron ore by these countries in the last years preceding the war and their recent maximum annual production are given below:

Table 21.—Maximum Annual Output and Normal Consumption of Iron Ore by Chief Iron- and Steel-Making Countries

The consumption figures represent metallic iron consumed in terms of iron ore and are obtained on the basis of production and imports of iron ore, and imports of pig iron and crude iron and steel products. Exports of iron ore, pig iron, and crude iron and steel products are not considered as forming part of the countries’ consumption.

A comparison of the consumption and production indicates that the United States, France, Russia and Austria-Hungary were self-supporting as far as raw materials for their iron and steel industry were concerned. Great Britain and Germany are dependent for a small percentage of their requirements upon foreign countries. Belgium produces a very small percentage of her consumption of iron ore, being almost entirely dependent upon foreign sources, mainly France and Germany, for her iron-ore requirements.

In several countries that produce much iron ore the iron and steel industry is still in its infancy. The iron ore from these countries is nearly all exported to the large iron and steel making countries. The following table shows the recent maximum annual production and normal annual consumption in some of these:

Table 22.—Maximum Annual Output and Normal Consumption of Iron Ore in Several Countries

Thus, considerable quantities of iron ore are available from these countries for consumption in countries that have to import iron ore and iron products.

There is shown below the pig-iron and steel production in 1913 of the world’s principal iron and steel manufacturing countries.

Table 23.—Pig-Iron and Steel Output of the Chief Producing Countries, 1913

—The United States has for many years had in the Lake Superior district the chief iron-ore producing fields in the world. In recent years the Lake Superior district has furnished more than two-fifths of the world’s output of iron ore. In 1917, 75,288,851 gross tons of iron ore, 38,647,397 gross tons of pig iron, and 45,060,607 gross tons of steel were produced in the United States, as compared with 61,980,437 tons of iron ore, 30,966,152 tons of pig iron, and 31,300,874 tons of steel in 1913. The imports of iron ore in 1917 amounted to 971,663 tons and of crude forms of iron and steel to 306,189 tons, as compared with 2,594,770 tons of iron ore and 250,592 tons of crude iron and steel products imported in 1913. The exports of iron ore from the United States in 1917 amounted to 1,132,313 tons and of crude forms of iron and steel to 4,744,527 tons, as compared with 1,042,151 tons of iron ore and 1,278,131 tons of crude forms of iron and steel exported in 1913.

These figures indicate that in normal times the United States consumes about 85 per cent. of the domestic output of iron ore, in the manufacture of finished iron and steel products. Fifteen per cent. is exported either as iron ore, or as crude iron and steel products which are manufactured into finished products in other countries. Of the finished iron and steel products made in this country the United States itself consumes the larger part. However, large quantities of iron and steel articles and machinery are exported to other countries as well.

The iron ore exported from this country is mainly Lake ore, which goes to Canadian furnaces. The iron ore imported is largely Cuban ore, which is used at the Sparrow’s Point plant of the Bethlehem Steel Corporation. This plant has facilities for using only ore arriving by boat and has been running almost entirely on foreign ores. The Cuban iron mines are largely under the control of this company, and an increased production is expected from them in the future.

The Bethlehem Steel Corporation has also developed an extensive iron-ore deposit in Chile, from which some shipments were made during the first years of the World War. It has been allowed to remain idle recently on account of lack of shipping facilities. Large shipments are expected from Chile in the future.

A considerable amount of Swedish ore has been imported in recent years by the Bethlehem Steel Corporation, to supplement its shipments of Cuban ore. During the war, however, the Trafikaktiebolaget Grängesberg Oxelosund decreased its ore shipments and finally refused altogether to export ore to the United States. These shipments recommenced soon after the cessation of hostilities in Europe.

Certain high-grade low-phosphorus iron ores which are not present in the United States in sufficient quantity to supply domestic needs have been imported in past years from Spain, North Africa, and to a small extent from Sweden. During the war, when the shortage of shipping facilities necessitated combing this country for supplies of high-grade low-phosphorus ores, it was shown that the United States is more or less dependent upon foreign sources for such ores.

There are a number of mines in the United States, such as the Lyon Mountain mine in New York, and the Cranberry mine in North Carolina, which produce limited amounts of high-grade low-phosphorus ore. Several mines on the Menominee Range, Michigan, produce a very siliceous low-phosphorus ore that can be used to supplement in part the high-grade ores. A considerable quantity of low-phosphorus pyrite residue from sulphuric acid and fertilizer plants is also used for making low-phosphorus iron. Much of the pyrite yielding this residue is imported from Spain, some of it is of domestic origin, and some of it comes from Canada. Altogether, the United States supplies about 60 per cent. of the material required for the manufacture of its normal output of low-phosphorus pig iron.

Certain developments in progress make it probable that a greater percentage of ore used for this purpose can be supplied from domestic mines. The principal enterprise is one that plans to concentrate the siliceous magnetite ore of the eastern Mesabi Range. Experiments have yielded a high-grade product and work on a commercial scale is planned.

The reserves of the ordinary grades of iron ore in the United States are large, and no shortage of such ore is anticipated for many years. They are easily capable of taking care of a considerably increased consumption. The largest reserves are in the Lake Superior district and in the southeastern states, but large untouched reserves occur in the western states as well. The iron ores in the Pacific Coast region have remained undeveloped from the lack of sufficient demand for pig iron and crude forms of iron and steel on the Pacific Coast. Undoubtedly this demand will increase in the future, and iron and steel industries will be established there.

The reserves of ore in the Lake Superior district are large. The grade of ore mined, however, has been gradually getting lower, and it is possible that before many years Lake iron ores averaging considerably below 50 per cent. will have to be utilized. At present the average grade of the ores mined in the Lake Superior district is about 51 per cent.

It is clear that there is not likely to be a shortage of the ordinary grades of iron ore in the United States. Reserves of high-grade ores, however, are being gradually depleted, and high-grade ores from foreign countries will find an increasingly ready market. American capital controls a large reserve of high-grade iron ore in Brazil. Much of the Brazilian ore averages about 68 per cent. in metallic iron and is very low in phosphorus, making it an exceedingly desirable raw material for the manufacture of special iron and for mixing with lower-grade domestic ores. Doubtless much of the Brazilian ore will go to Europe, as British and other foreign holdings of this ore are extensive. However, it is highly desirable that a certain proportion of the ore should be diverted to American furnaces.

—The annual consumption of iron ore in Germany just before the war was about 40 million tons, and the maximum annual output at this time, including more than 7 million tons from Luxemburg, was only about 34 million long tons. In order to supply German furnaces it was necessary, therefore, to import more than 6 million tons of iron ore from foreign countries. More than 58 per cent. of the iron ore mined in Germany has come from the Lorraine district. The production from German iron mines outside of the Lorraine district amounted to 6,906,809 tons in 1913. The production of pig iron during that year was 19,004,022 tons.

The pre-war imports of iron ore into Germany were large, amounting to nearly 14 million tons in 1913; against these the exports were somewhat more than 2 million tons.

The iron ore imported from Sweden is mainly high-phosphorus ore from the mines of Swedish Lapland and central Sweden. This is especially adapted to the manufacture of pig iron for the Thomas process, much used in Germany. Most of the ores from the Lorraine district are slightly too low in phosphorus to be suitable for the Thomas process; and Swedish high-phosphorus ores, phosphate rock, and phosphatic slags are in places mixed with Lorraine ore to raise the phosphorus content.

A considerable amount of low-phosphorus iron ore used in the manufacture of low-phosphorus pig iron is also imported from Sweden, and a larger amount of this ore is imported from Spain. This material is used in Germany for the manufacture of pig iron to be used in making acid open-hearth steel.

Since Germany has lost the Lorraine iron fields, the remaining domestic iron mines will be able to supply less than 20 per cent. of the requirements of iron ore for the German furnaces. However, it is likely that Germany will continue to receive most of her supplies from the Lorraine fields, in which German holdings at present predominate over French holdings and will probably continue to predominate.

—The United Kingdom has produced from 10 to 14 per cent. of the iron and steel of the world annually for the past 10 years or more, and apparently has consumed in normal times about 50 per cent. of the product and exported 50 per cent., mainly to British possessions. During the war about 75 per cent. of the British production was consumed at home and 25 per cent. was exported, largely to France. Fifty per cent. of the iron and steel products manufactured has been obtained from ores mined in Great Britain, and 50 per cent. from imported ores. Thus, normally, the domestic yield of iron ore just about equals the domestic demand for iron, whereas during the war the domestic demand for iron was greater than the domestic supply of ore. Great Britain depends upon outside sources for one-third of her iron-ore supply and this constitutes the source of about one-half of the iron products.

The iron industry in Great Britain before the war was loosely controlled by merchants who acted as intermediaries between producer and consumer, an arrangement that did not work to the advantage of the consumer.[49] British manufacturers had little interest abroad and were themselves insufficiently organized to operate successfully. If the sources of foreign iron ore were cut off, the situation might become critical and exceedingly embarrassing until the domestic mining industry could be expanded. To meet this condition the British Board of Trade Committee advised a consolidation of iron interests by the formation of a syndicate for the purchase and distribution of iron ores and particularly for the acquiring of interests abroad. This syndicate would establish sales agencies and arrange for transportation and trade, similar to the organization of W. H. Müller & Co., of The Hague. The committee recommended that these operations be backed by the government and that all the resources of the British Empire be under the control of the government, especially in regard to the granting of concessions to aliens and the imposing of restrictions to favor home producers. It has recently been reported that the iron interests have organized along the lines indicated.

—The annual consumption of iron ore in France for the manufacture of pig iron and crude iron and steel products amounts to about 12 million tons under normal conditions. The productive capacity of the iron mines of France is more than 21 million, leaving a surplus of 9 million tons of ore annually available for export. More than 90 per cent. of the iron ore produced in France is obtained from the Lorraine iron mines.

Most of the ore exported from France in the past has gone to German blast furnaces. Much has gone to Belgium. Imports of iron ore are small, being mostly high-grade ore from Sweden, in which class of ore France is deficient. French possessions in North Africa have large reserves of high-grade ore, but the bulk of the ore mined there has gone to England and Germany.

As a result of the war, that part of the Lorraine iron fields within the boundaries of the disputed provinces of Alsace and Lorraine has been given to France, who thus has control of the entire output of the great Lorraine iron fields with the exception of the part included in Luxemburg. The production of the Lorraine iron fields, including the part that formerly belonged to Germany, has been nearly 48 million tons annually, of which about 7 million tons is mined in Luxemburg. Outside of the Lorraine district France produces about 1,500,000 tons of ore. Thus, unless iron and steel making expand greatly in France, much iron ore will be mined for export.

—In 1913 Russia ranked sixth in the output of iron ore and fifth in the output of pig iron, producing about 4¹⁄₂ per cent. of the world’s production of iron ore and 6 per cent. of the pig iron.

Russia’s iron-ore reserves are estimated at about 1,600 million tons, a part of which, especially in central Russia, is not economically minable. The district of southern Russia is important on account of its large reserves, large output, and its location. This is particularly true at this time on account of Germany’s need of iron ore for future use.

The Russian output of iron ore grew from about 2 million tons annually in 1891-93 to 7 or 8 million tons annually in 1913-1917. Southern Russia (almost exclusively the Krivoi-Rog district) produced nearly 7 million tons in 1913, but by 1916 the production from this region had been cut down to half, its difference being made up from other regions.[50] Between 1913 and 1917, Russia produced about 4 million tons of pig iron annually, of which 3 million tons came from South Russia, and most of the remainder from the Ural region.

In 1916 the Central War Industry Committee estimated the monthly requirements of the whole country at 300,000 tons of pig iron for war purposes, and at 80,000 tons for the requirements of the civil population, making a total annual consumption of about 4,500,000 tons, or only about one-half of the normal consumption. In 1917, the total production in the country was estimated to amount to only 30 per cent. of these minimum requirements.

The situation in Russia is so unsettled that a statement of present conditions in the steel industry is valueless. It is reasonable to assume, however, that the iron and steel situation will not materially change as to operations and control. Moreover, it will be safe to predict that Poland will develop more rapidly as an iron-ore producer in the future, as she was handicapped in the past by restrictions on exportation of ore.

—Belgium has been negligible as a producer of iron ore but has been a comparatively large importer of iron ore and manufacturer of pig iron. The country ranked sixth as a producer of pig iron in 1913, in which year it produced 147,048 tons of ore and imported 4,400,000 tons.[51]

Belgian iron works were greatly damaged by the Germans during the war, and probably some time will elapse before the industry again reaches the position it occupied before the war. The country offers a good market, however, for the iron ores of France and should in future years be a larger producer of iron and steel wares.

Belgium is practically dependent upon outside sources for ore supply, but is conveniently situated as a market for ores from many countries. The total iron-ore reserves of the country have been estimated at 62,500,000 tons, not enough to last 10 years at the present rate of consumption.

—The former Austro-Hungarian Empire yielded in recent years 2 to 3 per cent. of the annual iron-ore production of the world, and about 2 per cent. of the pig-iron production; therefore it has been of minor importance in the iron industry. The ore reserves have been estimated at 284 million tons of available ore, and 807 million tons additional of probable ore.

The present unsettled conditions will probably result in considerable change in the operation and control of the iron mines and works. Eventually the upheaval may stimulate the iron industry, but the result should not materially alter the international position.

—The iron and steel industry of Japan is of small magnitude as compared with that of the United States, Germany, Great Britain, and other leading iron and steel manufacturing countries. The total reserves of iron ore are probably not much more than 60 million tons, or less than has been mined annually in the Lake Superior district in recent years. The steel-making industry is expanding rapidly, however, and at present blast furnaces, steel-making furnaces, and steel mills are being erected in Japan, Korea, Manchuria, and China by Japanese interests.

The output of iron ore in Japan is utterly inadequate to supply this expanding industry. The production of iron ore in Japan has averaged about 150,000 tons annually in recent years, whereas the consumption of crude, semi-crude and manufactured articles of iron and steel is approximately 1,500,000 tons. In order to supply her needs, therefore, from her own manufacturing plants, Japan would require in the neighborhood of 3 million tons of iron ore annually. As compared with this, Japan’s entire consumption of iron ore, both imported and domestic, is less than 700,000 tons. The remainder of the iron and steel required in Japan is being imported in the form of pig iron and crude and manufactured products.

Japan is making a strong effort to develop iron-ore deposits in neighboring countries, especially in China, Manchuria, and Korea; and the production from these sources which goes to Japanese-controlled furnaces is rapidly increasing. Among the more recent Japanese iron and steel enterprises in these countries are the blast furnaces and steel plant now being built at An-schan-chang, south of Mukden, in Manchuria; the blast furnaces at Pen-hsi-hu, southeast of Mukden, in Manchuria; and the blast furnaces at Ken-ji-pho, in Korea. The last two of these plants are now producing pig iron, which is being sent to Japan. In the future all three plants will probably build steel works. Iron-ore deposits are being mined in connection with all of them. Besides being used in the local blast furnaces, iron ore is being sent to Japan from these mines. In China, the most important iron and steel enterprise is that at Han-yang, in the Province of Hu-peh. This operation was started by the Han-Yeh-Ping Iron & Steel Co., as a Chinese enterprise in connection with the Tayeh mines in the same province. This company, however, became involved in financial difficulties, and Japanese capital was called upon in order that work might continue. Considerable expansion of the plant is at present taking place under Japanese supervision. Iron ore from the Tayeh mines and pig iron from the Han-yang plant are sent to Japan for use in Japanese iron and steel works.

It is doubtful whether, with the rapid expansion of the Japanese iron and steel industry, mines in China, Manchuria and Korea can be developed fast enough to supply the raw materials necessary. There are rumors that several deposits of iron ore in eastern China are now being developed, including that of Chin-ling-chen, and these may afford some additional supply. The iron mines of India also may be called upon to furnish more iron ore to Japan than they have done in the past. The only other important iron-ore deposits known elsewhere in the Orient are in the Philippine Islands. These deposits are reported to be fairly important and they are favorably situated for supplying Japanese plants. They are controlled by Americans.

The present expansion of the Japanese iron and steel industry is such that it is a question whether the consumption of iron products in Japan will be sufficient to take care of the entire output. It seems very probable that Japan is looking for a large export trade in iron and steel products. The Japanese may be ambitious not only to displace European and American goods in the Orient, but may even attempt to secure a market on the Pacific Coast of the United States and Canada. It is quite probable that Japanese manufactured articles will be able to compete in the western United States with articles manufactured in the eastern states and subject to heavy transportation rates. On the other hand, there is an active movement to start an iron industry on the Pacific Coast, and it is hoped that plants established there will be able to manufacture iron and steel products at a low enough cost to enable them to compete with Japanese products in the Orient.

Alloys of manganese are essential in the manufacture of steel by the open-hearth and the Bessemer processes, which produce 99 per cent. of the total output of the United States. In this country, about 14 pounds of metallic manganese as alloys, equivalent to about 40 pounds of high-grade ore, is used in making a ton of average steel. Two alloys are in common use: ferromanganese and spiegeleisen. Ferromanganese, with 70 to 80 per cent. manganese, is largely used in making open-hearth steel carrying less than 0.30 per cent. carbon, whereas spiegeleisen, with 20 to 32 per cent. manganese, is used in making Bessemer steel carrying more than 0.30 per cent. carbon. The first group of low-carbon steels is used in making structural shapes, sheets, bars, wire, etc., and the second group of high-carbon steels is used in making rails, forgings, etc.

In making 70 to 80 per cent. ferromanganese, so-called “high-grade” ore with more than 35 per cent. manganese and less than 5 per cent. iron and 15 per cent. silica is needed. In making 20 to 32 per cent. spiegeleisen, so-called “low-grade” or ferruginous manganese ore with 10 to 35 per cent. manganese, 20 to 35 per cent. iron, and less than 20 per cent. silica is needed, although here and there spiegeleisen is made by mixing high-grade manganese ore with iron ore.

Several other alloys such as silico-manganese, ferro-silicon, and ferro-carbon-titanium may be used as partial substitutes for ferromanganese, but although they may be capable of wider use under stress, they are electric-furnace products and under normal conditions their cost is prohibitive.

Very pure manganese oxide is used in making the common dry battery, the production of which has greatly increased with the wide use of the internal-combustion engine. About 25,000 tons is used annually in the United States for this purpose. The manganese oxide thus used is not consumed, but becomes exhausted through the loss of oxygen. Under stress of high prices, the oxide may be regenerated by treatment or by mixture with new refined material.

Small quantities of manganese ore are used in making many chemical products and pigments.

Any consideration of the need for manganese ore and ferromanganese and of dependence upon foreign sources of supply should take account of the degree to which low-grade ore and spiegeleisen may be used as substitutes for high-grade ore and ferromanganese. Thus, although both Germany and the United States have only insignificant resources of high-grade ore, both possess unusually large reserves of low-grade ore. Under recent conditions in the United States the percentage of total manganese used as spiegeleisen increased in three years from 10 to about 18 per cent. Competent authorities have estimated that this substitution may be further increased to nearly 70 per cent. with slight modifications in practice and modest addition of equipment. Some competent engineers further contend that by other modifications of practice a large part of the manganese now needed as alloys may be eliminated by the addition of low-grade manganese ore during early stages of the smelting and refining process.

Although concentrated masses such as are useful in the arts are rather uncommon, manganese is widespread throughout the earth; it forms a part of about 100 minerals and most of the common rocks, igneous as well as sedimentary, contain 0.1 to 2 per cent.

Present requirements as to grade are such that manganese ores are largely oxides. The carbonate, rhodochrosite, contains enough manganese to permit its use in making 80 per cent. ferromanganese, but only in a few places are the masses large enough to be the basis of extensive mining. The common silicate contains 43 per cent. manganese, but the silica content is so high (23 per cent.) that it can not be used alone in making the ordinary alloys.

The common oxides of manganese are deposited under many conditions which are found near the surface of the earth. Large masses of oxides were deposited in shallow marine waters, in shallow fresh-water basins and under many other conditions in the relatively thin mantle of weathered rock that is found over the entire world. Although most of these large masses were formed in the surface zone where the underlying unweathered rocks are unusually rich in manganese, some large masses of oxides accumulate under peculiarly favorable conditions by the concentration of small quantities of manganese disseminated through the common rocks.

For purposes of geologic study, deposits of manganese oxides may be considered in two groups, as follows: (1) those derived from more or less localized masses of carbonate or silicate materials, generally with more than 5 per cent. manganese, that seem to have no relation to the surface of the earth; and (2) those originally deposited near the surface as localized bodies of oxides.

Under the first group are zones of carbonate or silicate rocks in contact with intrusive igneous rocks, such as are found in Brazil and India. These zones contain manganiferous carbonates (mixed with iron, lime, and magnesia); and silicates (spessartite or manganese garnet and piedmontite or manganese epidote and possibly rhodonite, or manganese pyroxene). By the weathering of such rocks, large bodies of high-grade oxides have been formed.

Manganese also occurs in fissure veins or the adjacent wall rocks in regions that have been intruded by igneous rocks. The veins commonly contain rhodochrosite, manganiferous siderite, or rhodonite, associated with quartz and metallic sulphide minerals, including alabandite, the sulphide of manganese. Such veins are known in Philipsburg and Butte, Mont.; Silverton, Colo., and elsewhere. In such regions if the wall rocks adjacent to fissures are limestone or dolomite, they may be extensively replaced by manganiferous siderite or other carbonates which on weathering yield large bodies of manganese oxides, locally mixed with iron oxides. Such bodies are known at Leadville, Colo.

The manganese existing in sediments, notably clayey, but in part carbonate, may migrate locally after the sediments are slightly buried and form zones of manganiferous carbonate and silicate concretions parallel to the bedding. Where, as in the Batesville district, Arkansas, these zones are exposed by erosion, the manganese is further concentrated as masses of oxides in residual clay.

Metamorphic rocks, such as slates and schists, here and there, as in Spain, Newfoundland, California, and Washington, contain extensive lenses of rhodonite or other silicate with or without rhodochrosite, roughly parallel to the bedding. The origin of these lenses, which are generally rather remote from igneous intrusions, is obscure. Some are considered to be materials laid down during sedimentation, others are thought to represent concentrations effected during metamorphism when the sediments were deeply buried.

In the second group mentioned above (manganese deposits first concentrated near the surface as oxides) are included extensive deposits of oxides interbedded with marine sediments, as in the Caucasus region, Russia. Others interbedded with volcanic material, tuffs and flows, are known in the Mediterranean region and in Chile. In India important beds of oxides are interbedded with quartzite and slate.

Many deposits of oxides have recently formed and are probably now forming in bogs in many regions, notably New Brunswick, Canada. They are not important as sources of production.

Although no simple relation seems to govern the distribution of manganese in unweathered rock, there is reason for believing that the accumulation of manganese oxides in the weathered mantle is favored by climates that cause unusually complete or deep rock decay. Although a few manganese oxide deposits are found within the belts of recent glaciation, and some have no relation to weathering, most of the important deposits occur in areas now or recently favored with warm, humid climates, and there is reason for suspecting that such areas will yield other important deposits.

—In the United States, the occurrence of manganese ore can be most clearly described by grouping the districts according to grade or ore: (1) high grade, containing 35 per cent. or more of manganese, which is used ordinarily for making the high-grade alloy, ferromanganese, and (2) low-grade, ferruginous manganese ore, used ordinarily for the low-grade ferro-alloy, spiegeleisen. The country is deficient in natural supplies of the former, but has abundant resources of the latter, which under the stress of necessity could be largely substituted for the high-grade ore, which is now mainly imported.

The following districts in the United States yield high-grade ore:

At Philipsburg, Mont., are bodies of manganese carbonate that replace Cambrian limestone near veins and igneous contacts. These are weathered to oxides to a depth of about 200 feet below the surface. At Butte, Mont., veins in granite contain manganese carbonate and silicate, locally weathered to oxides.

In the Shenandoah Valley in Virginia, and in similar valleys in Tennessee and Georgia, the residual clays from certain Cambrian limestones and Silurian shale and sandstone yield bodies of manganese oxides to depths that range from 200 to 250 feet below the surface. Many small deposits also occur in Arkansas, Arizona, California, Nevada, and Utah.

The total production of the United States from 1838 to 1918 was 893,734 tons, and the maximum was 305,869 tons in 1918.

Among the chief districts yielding the lower grade of ore (10 to 35 per cent. manganese) the most conspicuous is the Cuyuna district in Minnesota, where beds of iron-manganese carbonate of pre-Cambrian age are weathered to oxides to depths of 250 to 500 feet below the surface and contain ore bodies carrying 7 to 20 per cent. manganese, and 25 to 50 per cent. iron. The single deposits range from 50,000 to 7,500,000 tons each. Since the first shipments in 1913, the production through 1918 has been 1,666,677 tons of ore carrying more than 5 per cent. manganese.

Large deposits of low-grade manganese ore also occur in the Leadville district in Colorado, where irregular bodies of iron-manganese carbonate have replaced magnesian limestone of Carboniferous age and are weathered to oxides to depths as great as 850 feet. From 1885 to 1918, the total production was 3,202,678 tons of material, most of which contained from 15 to 30 per cent. manganese.

Other deposits of ferruginous manganese ore have been exploited in Eagle County, Colorado; the Pioche district, Nevada; Silver City district, New Mexico; and in Arkansas, Georgia, and Virginia.

In Canada, large deposits of siliceous manganese ores occur in Newfoundland, and several small deposits in New Brunswick, Alberta, and British Columbia.

In Costa Rica, manganese occurs in four districts near Playa Real, Nicoya Peninsula, in the form of oxides that seem to be interlayered with sedimentary rocks. The most productive deposits are owned by citizens of United States and of Cuba; others are owned entirely by Cubans. They were first exploited in 1916, and to the end of 1918 had exported 18,000 tons to United States.

In Cuba, manganese is mined near Santiago and Bueycito, in the province of Oriente. Near Santiago, manganese oxides occur as lenticular or irregular bodies in tuff, clay, and limestone. Other deposits are reported in Santa Clara and Pinal del Rio provinces. The mines that have been the source of more than 90 per cent. of the exports are owned jointly by citizens of Cuba and of the United States, and the remaining mines by Cubans.

From 1888 to 1910, 266,621 tons were exported. In 1915, after four years of idleness, the mines were reopened, and imports into the United States from 1915 to 1918, inclusive, were 163,189 tons.[52]

In Mexico, manganese ores are found four miles north of Chihuahua City and south of Palomas, in the State of Chihuahua. It is assumed that the deposits are owned by native Mexicans. Manganese also occurs near Conception Bay, Lower California, where the mines are owned by native Mexicans but are under lease to Americans. From both of these districts, 1,500 tons were produced and exported to the United States in 1917.

In the Republic of Panama, near Nombre de Dios and Madinga, there are irregular lenses of manganese oxides in decomposed sedimentary beds. Seven groups of deposits were exploited near Nombre de Dios. Five of them were exploited by Americans, one by native owners, and one by French. The Nombre de Dios deposits yielded 50,000 tons of ore from 1871 to 1902, largely during the last six years. The Madinga deposits were opened in 1916 and during 1916 and 1917 exported 11,000 tons to the United States.

—The largest deposits of manganese ore in South America are in Brazil, and especially in the important mining state of Minas Geraes.

In the Lafayette district in this state, manganese oxides occur in wide lenticular bodies, that seem to have no definite arrangement or association, except that most of them are bounded by schist or gneiss. The deposits lie in a complex of granite, gneiss, and crystalline schists; and the manganese oxides are probably derived from manganese-bearing carbonate and silicate minerals. The most productive area, known as the Morro da Mina, 2,500 feet long by 1,000 feet wide, contains four distinct bodies that range from 320 to 1,300 feet long and from 48 to 320 feet wide. Here manganese oxides persist 410 feet below the surface.

The area has yielded about 1,000,000 tons of ore and the reserves are probably between 7,000,000 and 10,000,000 tons.

In the same State of Minas Geraes, in the Miguel Burnier and Ouro Prieto districts, manganese oxides are interlayered with ferruginous sedimentary rocks of pre-Cambrian age.

In the State of Bahia, the Nazareth district contains bodies of manganese oxide in a thick surface zone of highly weathered schistose rocks. The oxides are probably derived from lenses of manganese garnet in schist. The largest deposit yielded 70,000 tons of ore. Manganese deposits are also reported near Bom Fim, in the same state.

Other deposits of manganese ore in Brazil are reported in the states of Maranhao and Matto Grosso.

The known manganese deposits of Minas Geraes lie within an area about 30 miles square, the center of which is about 300 miles north of Rio Janeiro. The ore is readily mined from open cuts, but existing transportation and loading facilities practically limit the annual exports to 550,000 tons.

Most of the important deposits in the Lafayette-Miguel Burnier and Ouro Prieto districts are owned by resident Brazilians. In 1915 a German company had worked a part of the Morro da Mina deposit for six or seven years and produced a total of 200,000 tons of ore. During 1915 a Belgian company was operating the Cocuruto mine near Ouro Prieto and was shipping 2,000 tons monthly. The largest deposit of the Nazareth district is owned by an American and the undeveloped deposits near Turyassu are owned by Norwegians.

From the beginning of the industry in 1894 to 1918, 4,660,000 tons of manganese ore were exported from Brazil. From 1900 to 1913, the annual exports ranged from 99,000 to 250,000 tons, but with the elimination of Russian sources in 1914, exports rose to 503,130 tons in 1916, 532,855 tons in 1917, and 393,388 tons in 1918. In October, 1917, the export tax on manganese ore was advanced from $0.85 to $3.00 per metric ton. Even before the war a large part of the Brazilian exports went to the United States. The destination of the 1913 exports was as follows: United States, 60 per cent.; Germany, 18 per cent.; Great Britain, 16 per cent.; France, 6 per cent.

In Chile, manganese ores occur at Corral Quemada, and nearby districts in the State of Coquimbo. In these districts, beds of manganese oxides are interlayered with sandstone, shale, and volcanic flows. Manganese is also found in the Carrizal district in the State of Atacama, where beds of manganese oxides are interbanded with shale and limestone. From 1885, when explorations were begun, to 1905, the exports of manganese ores from Chilean ports amounted to 549,716 tons, the maximum exports for one year being 50,871 tons, in 1892.

In Uruguay, deposits of ferruginous manganese ore, reported to contain 80,500,000 tons, occur at Zapucay, in the Department of Rivera.

—In the former empire of Austria-Hungary, the principal manganese district is near Dorna Vatra, in Bukowina. Here there are lenses of manganese carbonate and silicate in schists that have weathered to oxides near the surface. The deposits are owned by the Bukowina Greek Church. The average annual production from 1906 to 1912 was 13,600 tons. Other deposits are reported in Bohemia, Istria, Styria, Hungary and Bosnia. Since 1901, the production of Austria-Hungary has ranged from 18,000 to 25,000 tons annually.

In Belgium, near Chevron, in the Province of Liège, ferruginous manganese oxides have formed by the weathering of manganese and iron carbonates. Since 1901, the annual production in peace times has ranged from 2,000 to 15,000 tons.

In France, manganese occurs chiefly near Romaneche, in the Department of Saone and Loire, where several bodies of manganese oxides lie in a fault between sedimentary rocks and granite. The deposit has been known since 1823, and the production in 1901 was 9,500 tons. Other French deposits have been explored in the Departments of Hautes-Pyrenees, L’Ariege, L’Allier, L’Ande, and La Nievre. The annual production rather steadily declined from 22,000 tons in 1901 to 6,000 tons in 1913. The ownership of the French manganese deposits seems to be largely French, possibly aided by some English capital.

In Germany, manganese ore of the better type, containing over 30 per cent. of the metal, occurs in Sachsen-Gotha, Central Germany, in small veins of manganese and iron carbonates weathered near the surface to oxides. A similar grade of manganese ore occurs in small quantities at Hessen and Waldeck, in Rhenish Prussia.

Manganiferous iron ore, containing from 12 to 30 per cent. of manganese, occurs in Hessen-Nassau, Rhenish Prussia, where manganese and iron oxides form irregular flat lenses imbedded in clays derived from the weathering of underlying Devonian limestone. During the period 1907 to 1911, nine deposits yielded 262,000 to 283,000 tons annually.

Manganiferous iron ore (containing less than 12 per cent. manganese) is found at Siegerland and at Nassau, Rhenish Prussia. The veins are large and contain manganiferous siderite; they cut Devonian sediments. These deposits are largely owned by the principal iron works of Rhenish Prussia. During the period 1907 to 1911, the annual production ranged from 2,200,000 to 2,600,000 tons.

In Great Britain, the principal deposits are in North Wales. Veins of manganese carbonate and silicate, as well as interlayered lenses, are found. The material contains 20 to 36 per cent. manganese. Other deposits are recorded in Devonshire, Cornwall, and Shropshire. The maximum production of Great Britain of about 23,000 tons was attained in 1906, when two mines in North Wales yielded 19,300 tons.

Manganese occurs in Greece, in the western end of the island of Melos, where nodules and masses of manganese oxides are disseminated through beds of tuffs of Pliocene age. The maximum production of 15,000 tons was recorded in 1902. The output has since steadily declined to 550 tons in 1913. Manganese also occurs on the peninsula of Kassandra, which was formerly in European Turkey. A vein explored mainly for argentiferous galena yields manganese oxides from the surface zone. The maximum production of 52,000 tons was attained in 1902, steadily declining thereafter to 12,000 tons in 1910.

In Italy there is manganese in Tuscany, where irregular bodies of manganese and iron oxides occur in Triassic limestones. Other deposits in Liguria and Sardinia have recently yielded a little ore. Of the maximum Italian production of 18,147 metric tons (18 to 45 per cent. manganese) in 1916, 14,072 metric tons was derived from the Tuscany deposits in Tuscany. Normally the annual production has ranged from 1,600 to 4,700 tons.

In Portugal there is manganese in Alemtejo. The deposits, reported to be lenses and veins in Silurian quartzites, are owned by a Portuguese company.

Russia contains the most important manganese deposits in Europe, if not in the world. The principal mining district is near Chiaturi, in the Kutais Government, on the south side of the Caucasus Mountains, in southern Russia. Layers of oolitic grains of manganese oxides are interbedded with horizontal sandstone and shale of Lower Eocene age. Within a zone that ranges in thickness from 4.5 to 7.5 feet and averages about 6.5 feet, seven distinct layers of very pure manganese oxide aggregate about 40 inches in thickness, and the remainder is low-grade material and sand. It is estimated that an area of 120 to 143 square kilometers was originally underlain by the bed of oxides, but that about half has been removed by erosion. Estimates of reserves range from 23,000,000 tons to several hundred million tons.

The mines are operated in a crude, inefficient manner and scarcely two-thirds of the ore is recovered. The number of actual producers ranged from 183 in 1902, to 376 in 1906, but declined to 96 during the political troubles in 1908. The ore is sorted by hand and the low-grade material is washed in crude plants. From 20 to 25 per cent. of the exported material has been concentrated by washing.

In 1902 there were 5,000 concessions, of which 3,750 were owned by 14 persons, each with 25 to 500 concessions; the remainder belonged to 300 peasants and small merchants. By 1912 a producers’ association had been formed to permit the owners to deal collectively with the exporters. Large investments had also been made by German capitalists in mines as well as in undeveloped territory. The Gelsenkirchen Gesellschaft, a German firm, had been formed partly for the purpose of mining but largely to purchase and export ore to Germany. In 1912, this firm, although it produced only a little ore, exported nearly one-third of the total. German groups also established necessary financial agencies to facilitate export of ore as well as to make loans to mine operators. In 1913, of 16 exporting firms, only 3 were Russian.

The output of the mines of the Chiaturi district is hauled to Chiaturi (1.3 to 3.3 miles), loaded on narrow-gauge cars for transport to Sharopan (25 miles), and then reloaded on cars for shipment to Poti or Batum (107 miles), the ports of export. Large stocks ranging from 1,030,000 tons in 1912, to 1,525,000 tons in 1908, are kept at Chiaturi, Poti and Batum. From 1910 to 1912, the distribution of exports ranged as follows: Holland (for Germany), 30 to 43 per cent.; England, 22 to 23 per cent.; Belgium (largely for Germany), 15 to 21 per cent.; Germany (direct), 5 per cent.; France, 4 to 6 per cent.; United States, 4 to 10 per cent.; Austria, 4 to 10 per cent. About 1913, an export tax equal to 40 cents per long ton was levied by the Russian government.

It is estimated that from 1848 to 1914, inclusive, this deposit yielded about 11,000,000 tons of washed ore of marketable grade. The maximum production of 1,300,000 tons was attained in 1913.

Another important manganese mining region is the Nicopol district, in the Province of Ekaterinoslav, north of the Black Sea. In this district a bed of manganese oxides lies between clays and sandstone of Oligocene age. This bed is 1 to 5 feet thick, averaging nearly 3 feet. It is estimated to extend over an area of 20 square kilometers (7.5 square miles) and to contain 7,400,000 tons of manganese ore. The ore is mined and washed in a crude way to free it from the attached clay.

The deposits in this district are probably owned largely by Russians, although French capital is interested in one company and German capital in another. During the period 1901 to 1910, between 80 and 90 per cent. of the production was consumed in southern Russia and the remainder was exported. From 1886, when the deposits were first exploited, the output rose rather steadily to the maximum of 271,000 tons in 1907, then declined to 173,000 tons in 1910. The total production of the district is about 1,800,000 tons.

Manganese deposits are also known in the Province of Podolien and Terek, and in the governments of Tiflis, Erwin, Elisabetpol, and Perm.

The principal manganese deposits of Spain are on the south slope of Sierra Morena, in the Province of Huelva. Vertical lenticular bodies of manganese carbonate and silicate with a little pyrite, garnet, and mica occur interlayered with slate of Paleozoic age. About one hundred bodies are known, many being 500 feet long and 100 feet wide, whereas the largest is 3,300 feet long and 330 feet wide. The manganese minerals are weathered to oxides to an average depth of 65 feet and a maximum depth of 250 feet. From 1881 to 1905, when the oxide ores were nearly exhausted, nearly 700,000 tons had been shipped. From 1906 to 1910 about 125,000 tons of mixed carbonate and silicate was produced.

Manganese is also found in the Covadonga district, Province of Oviedo, where large boulders of manganese oxide are found in clay resulting from the weathering of underlying limestone. These deposits yielded 3,800 tons in 1915. Other productive deposits occur in the provinces of Seville and Teruel. Deposits are also known in the provinces of Ciudad Real, Murcia, and Almeria.

In Sweden, there are manganese ores north of Philipstad, in Wermland, where tabular bodies of manganese oxides are interlayered with dolomite and magnetite. These deposits contributed 7,607 tons out of a total of 7,733 tons in 1915, which was the maximum recorded production of Sweden.

—In India, on the east coast in the Vizagapatam and Ganjam districts, Madras, is a unique group of rocks known as the Kodurite series, containing manganese garnet, manganese pyroxene, potash feldspar, apatite, and quartz. These rocks, supposed to be of igneous origin, have been deeply weathered and the manganese concentrated as oxides in the surface zone. The manganese ore bodies have been explored only to 100 feet in depth, but it is expected that they will extend to 500 feet. The largest ore body explored at the Garbham mine is 1,600 feet long and 100 feet wide, and, from 1896 to 1913, yielded 736,192 tons of ore. The Kodur deposit yielded 370,382 tons of ore from 1892 to 1913. Production began in 1892, reached a maximum of 111,501 tons in 1906, and slowly declined to 44,127 tons in 1913.

Manganese also occurs in the Balaghat, Bhandara, Chindwara, and Nagpur districts in the central provinces; Narukot and Panch Mahals districts, Bombay; Jhabua district, central India; and the Gangpur district in Bihar and Orissa. These districts form a belt that extends from Baroda, on the west coast, across northern India nearly to Calcutta on the east, a distance of 700 miles. In these districts, beds of manganese oxides with manganese garnet and rhodonite form a rock type known as gondite, which is interlayered with quartzite and mica schist. These rocks are considered to be sediments of the Dharwar group (Archean). The manganese oxides may have been laid down as sediments, or may represent the weathering of the silicates. The ore bodies are lenses and layers. The largest single deposit, Balaghat, has the form of a shallow trough, is 1³⁄₄ miles long and 45 to 50 feet thick, and yielded from 1901 to 1913, 725,248 tons of ore. In 1913, thirteen distinct deposits had yielded more than 100,000 tons each, the range being from 101,721 to 725,248 tons.

From 1901, when the deposits of this type were first exploited, the rate of production rose steadily to the maximum of 697,035 tons in 1913. During 1907, fifty-two separate deposits contributed 598,437 tons.

Where rocks of Dharwar age (Archean), such as mica schists, that do not seem to contain the manganese-bearing Gondite series, are deeply weathered, manganese and manganiferous iron oxides form irregular but locally extensive deposits on the crests of hills. These deposits are underlain by barren clays that represent the residue of the underlying rocks. The largest deposit yielded 160,000 tons of ore in three years, 1906 to 1908, but is probably almost exhausted. The principal deposits of this class are in the Sandur Hills district, Madras; the Shimoga district, Mysore; and the Belgaum district, in Bombay; which lie within an area less than 100 miles in diameter in southwest India. From 1905, when deposits of this group were first explored, the production increased to a maximum of 11,353 tons in 1909,then declined to 62,770 tons in 1913. The total yield of this group to the end of 1913 was only 765,401 tons.

As regards the commercial control of the manganese deposits, a law recently passed forbids aliens to own more than a minor interest in mineral deposits in India. Previous to this, during 1907, the latest year for which complete data are available and in which 899,055 tons was produced, the entire output was from mines owned by resident English or natives, except for 21,500 tons produced by the Carnegie Steel Co., of Pittsburgh, U. S. A.

The annual production of manganese ore in India rose steadily from 1892, when the first shipments were made, to 1907, when 899,055 tons was shipped; and since then has ranged from 450,000 to 815,000 tons. The total production, up to and including 1916, was 8,748,000 tons.

Indian ores are transported to the shipping ports by rail for distances ranging from 56 miles for the Vizagapatam district to 783 miles for the Chindwara district, with the result that freight charges are heavy. The ports of export in order of tonnage handled are, Bombay, Mormugas, Calcutta, and Vizagapatam. The destination of exports in 1913 was as follows: United Kingdom, 36 per cent.; Belgium (largely to Germany), 26 per cent.; United States, 15 per cent.; France, 14 per cent.; Germany, 2 per cent.; others, 7 per cent.

In the Japanese Empire, in the islands of Mutsu, Echigo, Ugo, and Nato, are irregular lenticular bodies of rather pure manganese oxides that occur more or less parallel to the bedding of metamorphosed Paleozoic sediments. Below water level, the oxides grade into rhodonite and are probably derived from this mineral. The ore bodies are not large, but many are known and they are the source of a small but regular production. In the islands of Mutsu, Nogo, Hokkaido and Ugo many irregular but locally large deposits of manganese oxides are associated with highly altered volcanic tuffs and flows of Tertiary age. Most of the deposits in Japan seem to be owned by natives in small holdings. The maximum production of 18,076 tons is reported for 1913, but since 1900 the range has usually been from 5,000 to 15,000 tons.

In the Philippine Islands, manganese occurs on the islands of Ilocos Norte, Masbate, Bulacan, Pangasinan and Tarloc, largely as veinlets and boulders of oxides in weathered igneous rock. On Ilocos Norte a maximum production of 3,000 tons was attained in 1916.

—On the Gold Coast of West Africa (a British colony), near Dagwin, are several deposits of manganese, the largest being 400 feet long and 70 feet wide. The concession is owned by a British exploration company. The deposit was discovered in 1914; and from the beginning of exploration in 1916 up to November 7, 1917, 28,465 tons had been shipped to England.

In the Belgian Congo, there is manganese ore in the valley of the Upper Fungwe River, and in southern Katanga. The deposits are too remote from the ocean to justify exploration, but are reported to be large. In the Union of South Africa (British) several manganese deposits are found along the sea coast, within 30 miles east and west of Capetown. Of the seven known deposits the largest is estimated to contain 15,000 tons. In Egypt, in the Sinai peninsula, are large manganiferous iron deposits as well as small manganese deposits, but none has been exploited. In Tunis, there are deposits reported to contain 4,000,000 to 5,000,000 tons of manganiferous iron ore, and also several manganese deposits which yielded 5,800 metric tons of manganese ore in 1917.

Although the known deposits of manganese in Africa are few and relatively unimportant, the continent offers an unusual prospect for the discovery of deposits that will contribute largely to the world’s supply. Inasmuch as the moist tropical climate of large areas favors extraordinary rock decay and surface concentration of manganese oxides, exploration will probably show the presence of many deposits, and where bedrock geological conditions are favorable, large bodies may be found.

—In Australia, there are deposits of manganese ore in New South Wales, in Queensland, in South Australia, and in Victoria.

In New Zealand, deposits of manganese ore occur in the Thames district, Auckland.

Deposits of manganese ore are known in Borneo, at Maruda Bay.

Fig. 5.—Annual output of manganese ore in chief producing countries.

Fig. 6.—Percentage of manganese ore produced by chief producing countries.

It is reported that large deposits of high-grade ore have recently been discovered in Java.

Some statistics of the production of manganese are shown graphically in figures 5 and 6.

The known manganese resources of Russia, India, and Brazil are so large and readily available for exploitation and marketing that there is little prospect of their being displaced as the chief sources of the world’s supply for many years. Since the war began, in 1914, several important new districts have been discovered and brought to the producing stage, notably the Gold Coast of West Africa, western Costa Rica, and Java. Although the Javan deposits are reported to be large and may become an important factor in the world’s trade, all that is known concerning the other deposits does not hold out much hope that they can compete with the established sources.

There appears to be a fair chance that the equatorial belt as well as several other parts of the earth may yield additional important manganese deposits.

The distribution of the manganese deposits of the world is shown in Plate III.

The table of production for 1913 on page 105 shows the part of the total that each country contributed and the known extent of commercial control.

In contrast with deposits of several other important minerals, most of the manganese deposits throughout the world are owned by natives or residents of the respective countries in which they are found.

German companies have acquired tracts in the Chiaturi and Nicopol districts, Russia, and Queluz (Lafayette) district, Brazil. It appears that although one of these companies produces a little ore, the main purpose was to stabilize an unorganized industry by financial assistance.

In India it is difficult to distinguish between those companies composed of resident English and native Indians which were formed to exploit mines for profit and those composed of absentee English who desire to secure a supply of ore for English or other consumption. There seems to be no English capital in Brazil or Russia.

One French company owned two shipping mines in India in 1907, but there is no record of operations in 1913. French capital is interested in several companies busy in the Nicopol district, Russia. A Belgian company operates one mine in the Queluz district, Brazil.

Table 24.—Production and Commercial Control of Manganese

The Carnegie Steel Co., of Pittsburgh, Pa., U. S. A., owns and works several deposits in India. Although Americans own deposits in the Nazareth district, Brazil, in Panama, and Costa Rica, and some of those of Cuba, there is no record of American ownership of any of the most important deposits of Brazil, nor of any in Russia.

From 1902 to 1914, about half the ferromanganese used in the United States was made in this country from foreign ore and half was imported from England, where it was made from imported ore. This tendency arises out of the limitations of blast-furnace smelting of the alloy and the difference between the cost of labor in the United States and in England, but does not represent definite control, for ferromanganese may be made in any modern blast furnace used to make pig iron. In order to smelt with maximum efficiency in making ferromanganese, however, a blast furnace should run continuously for long periods, and therefore make 20,000 to 35,000 tons of alloy annually. Although it is possible to pass without interruption from making ferromanganese to spiegeleisen and then to pig iron, the change causes losses. Small steel works in the United States therefore find it more advantageous to purchase imported ferromanganese than to make what they need.

—Although from 1885 to 1890, deposits in the United States supplied half or more of the needed high-grade manganese ore, from 1890 to 1916 the domestic production rather steadily declined to a negligible minimum, while imports of foreign ore and ferromanganese steadily rose in accord with the rate of total steel production. On the other hand, during the period ending about 1908, when the rate of manufacture of steel by the Bessemer process (in which spiegeleisen is largely used) exceeded that by the open-hearth process, the annual domestic contribution of spiegeleisen largely made from domestic ores greatly exceeded the imports. In advance, therefore, of the exploitation of the large deposits of low-grade ores of Minnesota, which have been the source of most of the production since 1916, the United States demonstrated independence of foreign supplies of low-grade ore and alloys.

The experience and information gained during the war, largely during 1918, show conclusively, first, with respect to metallurgy, that 20 to 30 per cent. spiegeleisen, as well as 60 to 70 per cent. ferromanganese, instead of 80 per cent., may be used to make satisfactory grades of open-hearth steel without appreciably sacrificing rate of production or quality of product; and second, with respect to ore production, that known domestic deposits can supply for at least five and probably ten or more years, much more low-grade ore than is needed to make spiegeleisen, and for at least five years and possibly ten years, about one-third the high-grade ore needed for the manufacture of alloy with 60 to 80 per cent. manganese. The reader should note, however, that capacity of mines to meet demand is in large measure determined by the prices offered for the product, which during 1918 were about five times those prevailing before the war. Beyond doubt, at pre-war prices, the United States can not supply more than several per cent. of the high-grade ore needed to make ferromanganese.

Citizens of the United States have not shown great interest in purchasing foreign deposits of manganese ore. With Cubans, they have controlled the mines yielding a large part of the Cuban output, and about 1907 one company, the Carnegie Steel Co., purchased several deposits in India. That company, however, seems to purchase ore, in addition to the output of its mines. Not until 1917 did Americans enter the Brazilian fields; then the largest deposits of the relatively unimportant Bahia district were purchased by a Philadelphia group.

—Before the war, England received about 50 per cent. of her manganese ore from India, 40 per cent. from Russia, 3 per cent. from Brazil, and small quantities from Spain and Portuguese India. Some low-grade ore also came from Spain, Algeria, and Greece. Domestic production was scarcely 1 per cent. of imports. Exports of ferromanganese, largely to the United States, however, have been equivalent to 35 to 45 per cent. of the total imports of ore. Two effects of the war were to eliminate Russia as a source of ore, the deficit being made up from India, and greatly to curtail exports of ferromanganese. In contrast with the United States and Germany, Great Britain does not seem to contain deposits of low-grade ores capable of supplementing the needs of high-grade ore.

England controls fully 90 per cent. of the Indian output, probably through ownership by resident English and native Indians. On the other hand, England seems to have no control, direct or indirect, of the output of Brazil, Russia, or of other important contributions to supplies.

—Of the needed manganese ore, France imports from 35 to 45 per cent. from India, 40 to 55 per cent. from Russia, about 10 per cent. from Spain, and several per cent. from Brazil, and produces about 2 per cent. The domestic material, however, contains 30 per cent. or less manganese. In addition, France imports, as well as exports, a little ferromanganese from time to time.

So far as available data indicate, the French have made practically no foreign investments in manganese deposits, except in the Nicopol district, Russia. A company with a French name mined about 1,300 tons in India in 1907, out of a total of 899,055 long tons.

—Germany’s position with respect to manganese is very similar to that of the United States. For four years prior to 1914, Germany imported 48 to 68 per cent. of the total receipts from Russia, 25 to 35 from India, 3 to 7 from Brazil, and small quantities from Spain, Greece, and Sweden. Domestic production of ore with more than 30 per cent. manganese is negligible. Germany probably exports small quantities of ferromanganese to Sweden and other European countries, and from time to time has exported alloy to the United States.

Like the United States, however, Germany possesses extensive deposits of ferruginous manganese ore with 12 to 30 per cent. manganese; and from 1908 to 1913, produced 260,000 to 330,000 metric tons of such material, as well as 2,300,000 to 3,000,000 tons with 5 to 7 per cent. manganese. There can be little doubt that although Germany, through accumulated stocks of manganese ore and seizures in Belgium, possessed in 1914 at least two years’ supply, she was able to maintain a fairly constant rate of steel production for four years by adapting processes to economize high-grade ore and use low-grade.

Germans appear to have purchased manganese deposits in Russia and Brazil only, and these have yielded only a small part of the annual imports. In the Chiaturi district of Russia, however, where most of the deposits are owned by natives, a German company, Gelsenkirchen Gesellschaft, reported to be a subsidiary of the Krupp company, was established about 1910, to purchase property as well as trade with and offer financial assistance to the producers. It is reported that this company alone exported about one-third of the output of the district. Germans are reported to own a part of one of several companies operating in the Nicopol district, Russia.

A review of the manganese ore industry, including features of the deposits, their geographic distribution and ownership, indicates several definite conclusions:

1. The surface outcrops of most manganese deposits give reliable information concerning the size and grade of the deposits, and the most desirable ore occurs in a surface zone scarcely 100 feet deep.

2. Except in Russia and Spain, the most productive mines are open-cuts, and mining is quickly and easily accomplished at minimum expense. Extensive operations in advance of production are rarely necessary.

3. The countries that possess the largest and richest deposits have an abundant and cheap labor supply.

4. The productive capacity of the known deposits so much exceeds the world’s demand for ore for steel making, that if any single source is temporarily eliminated, the demand can be wholly met by the remaining sources at prices that are only slightly higher than those previously prevailing.

5. The value of the material at the sources of production is relatively low among raw minerals, and ranges from one-third to one-eighth of the selling price at the points of consumption. It is evident that the cost of transportation represents a large part of the final price.

6. The working of most deposits yields so little profit, and therefore is so hazardous, that only a few foreigners own deposits in the chief producing countries.

7. The only case of commercial control, that of the Chiaturi district, Russia, by Germans, who offer the natural market, seems to have been established to counteract local political disorders rather than to eliminate competitive consumers.

8. No nation that contributes largely to the world’s steel production, except Russia, possesses domestic deposits of manganese ore sufficient to meet its needs, and all must import ore from rather remote sources. The United States and Germany, however, possess domestic deposits of ferruginous manganese ore that under great stress would probably permit independence of foreign sources.

Chromite is the principal ore from which metallic chromium and chromium products are obtained. The theoretical composition of chromite is represented by the formula FeO Cr₂O₃, which represents 32 per cent. ferrous oxide and 68 per cent. chromic oxide. In many ores, however, the ferrous oxide is partly replaced by magnesia, up to 30 per cent., and the chromic oxide by alumina and ferric oxide, up to 20 per cent. Thus the composition of chromite varies considerably. The percentage of chromic oxide may be as low as 10 per cent.; that of ferrous oxide may range from 10 to 50 per cent. Other common minerals of chromium are picotite (chrome spinel), uvarovite (chrome garnet), chrome diopside and crocoite (lead chromate).

Chrome ore is consumed mainly in the manufacture of special steels and in tanning leather. The special steels comprise chrome steel, chrome-nickel steel, chrome-tungsten steel, and chrome-vanadium steel. Metallic chromium is added to such steel in the form of ferrochrome, an alloy of chromium and iron containing 60 to 70 per cent. metallic chromium. Chrome steel is tough and hard to break. It hardens rapidly and has a fine grain and a fibrous fracture; it does not break readily upon concussion and because of its hardness is difficult or impossible to cut with ordinary machine tools. Metallic chromium is present in percentages varying from 1 to 5 per cent. Special steels containing chromium are used for guns, armor plate, armor-piercing projectiles, automobile parts, machine tools, bars for prisons, burglar-proof safes, shoes, cutlery, crusher jaws, stampmills, springs and for other articles in which hardness and toughness are necessary. During the war, when a considerable shortage of chromite threatened, less chromium was used in chrome steels, and certain other hardening materials were used in its place. The results are said to have been unsatisfactory, however.

Ferrochrome used in the manufacture of chrome steels is produced in the electric furnace by smelting a mixture, in proper proportions, of chromite, coal or coke, lime, and fluorspar or silica.

Much chrome ore is used in the steel industry for refractory materials in lining open-hearth furnaces. Some of the ore thus used is first manufactured into chrome brick and some is utilized in the crude form. Chrome brick is used in open-hearth furnaces as a lining along the slag line between the magnesite bottom of the furnace and the silica-brick sides and roof. Chrome brick is used also to cover the ports of gas-fired furnaces. It is desirable for these purposes on account of its neutral reaction, which reduces the wear due to corrosion. Lump or crushed chromite is used for patching the bottoms of open-hearth furnaces, particularly the toe or apex of the bottom, the ore being either hammered in place as lump or crushed and mixed with a little water or tar and clay and then tamped into place. The use of lump chrome in repairing such furnaces is desirable on account of the rapidity with which the furnaces can be repaired and on account of the greater wear that chromite will stand. The amount of chromite used for this purpose ranges from 2 pounds to 10 pounds per ton of steel manufactured. Magnesite has been used to replace chromite for repairing furnaces, but has been found to be more expensive and to stand less wear.

Chrome brick is used in a minor way in electric furnaces for manufacturing steel, in a belt along the slag line and in the area around the pouring lips. It is also being used in furnaces manufacturing steel by the duplex process.

Chrome brick, besides being used in steel-making furnaces, is used in lining furnaces for making copper, nickel, and other metals. In these furnaces it is used in the bottoms and around the tap holes. Magnesite brick, as well as bauxite brick, have been used to replace chromite brick for this purpose.

Chromium chemicals used for tanning are mainly sodium or potassium bichromates. About half of the bichromates produced in the United States is commonly used for tanning, the remainder being used for paints, pigments, dry colors, and dyes in the paint, printing and engraving, and textile industries. Chrome yellow, chrome orange, and chrome black are used in calico printing and dyeing. Chromic oxide, or chrome green, is an indelible pigment employed in printing banknotes. Various other chrome colors are used for paints and pigments as well as in the ceramic arts. The minor uses of chrome chemicals are many.

Chromite throughout the world is associated with basic igneous rocks, such as peridotite or pyroxenite, or with the alteration products of these rocks, such as serpentine, talc schist, and related rocks. Chromite deposits are generally in the form of lenses, pods, or irregular masses that may occur singly or may be associated in groups. Besides being found as large bodies, chromite occurs as a minor constituent of these rocks, being widely disseminated through them as small specks and particles. Chromite that forms workable deposits is believed to have been separated out of the molten mass of basic igneous rock by segregation and to have formed separate bodies within the rock mass during the cooling. Most chromite deposits are found along the borders of intrusive masses not far from the contact of older rocks into which they are intruded. This is probably due to the formation of peripheral fractures during the cooling of the igneous mass, chromite being forced up into these openings. The action of convection-currents in the molten magma may also have resulted in localizing chromite bodies near the borders of the mass. However, bodies of chromite are quite abundant in other parts of the igneous masses as well, often being found at long distances from bordering rocks.

By weathering of chromite-bearing igneous rock, chromite bodies are freed and occur as loose masses in resultant residual clays. Such bodies in clay are of commercial importance in many places. The breaking down of chromite-bearing rocks results in setting free disseminated specks and particles of chromite, and these may be transported and later deposited along streams flowing out of chromite-bearing areas. In this manner accumulations of chromite sands are formed. Besides chromite, these sands usually contain considerable quantities of other heavy minerals such as magnetite, ilmenite, garnet, and rutile, and the chromite in them is generally not available commercially.

The world’s chromite supply has been obtained mainly from the following sources, named roughly in order of their importance:

New Caledonia; southern Rhodesia; western and southern Asia Minor; Ural Mountains, Russia; eastern Greece, adjacent islands, Macedonia, and Serbia; Baluchistan and Mysore, India; Quebec, Canada; Atlantic and Pacific coast states, United States; State of Bahia, Brazil; Oriente, Cuba; Japan; Bosnia and Herzegovina; Austria-Hungary; and Guatemala.

The geographic distribution of the more important deposits of chromite is shown in Plate IV.

Other countries in which deposits of chromite are known but in which little or no ore has been produced are: Shetland Islands, Scotland; Norway; Sweden; Silesia; Portugal; New South Wales, Australia; New Zealand; Transvaal; Togoland; and Newfoundland.

Table 25 shows the output of chromite in the chief producing countries from 1905 to 1917.

—Important quantities of chromite occur on the island of New Caledonia, in the South Pacific, and in smaller amounts in Australia, New Zealand, and Tasmania.

Table 25.—World’s Chromite Production 1905-1917 in Long Tons[53]

Serpentine, in masses intruding metamorphic rocks and sediments ranging in age from Archean to Mesozoic, is abundant throughout the island of New Caledonia, and chromite invariably is associated with it as a minor constituent. Locally, large masses of fairly pure chromite are found, generally as lenticular bodies in the serpentine, but locally as irregular masses in residual clay derived from the decomposition of the serpentine.

Chromite deposits of three types are known in New Caledonia, as follows: Rock chrome, consisting of solid ore bodies in serpentine; residual chromite, as irregular bodies or scattered masses, frequently disintegrated, in red residual clay derived from the weathering of the serpentine; and chrome sand and gravel in surface wash and stream deposits. Ores of the first two classes are both important commercially in New Caledonia and are both present in most mines. Ores of the last named class are not worked.

Of these New Caledonian deposits, that of Mt. d’Or, in the southern part of the island, was the first to be discovered and worked, being found by Garnier in 1866. Later the deposits of Ngo Bay and others further south were exploited. Production and exportation of New Caledonian chromite began in the early 80’s and continued in a minor way until 1902, the production coming mainly from Mt. d’Or and the Ngo Bay deposits.

In 1902, L. Bernheim formed the Société le Chrome, in which French capital was largely interested. This company operated mines in the northern and southern parts of the island. It developed the Tiebaghi deposits near the port of Pagoumene, now among the most important in New Caledonia. The exportation of chromite soon increased, and gradually New Caledonian ore replaced Turkish ore in the market. In 1911 the Chrome Co., Ltd., of London, was formed and acquired from the Société le Chrome the Tiebaghi and other mines. At the same time it acquired the right from the Rhodesia Chrome Mines Co., Limited, to market the Rhodesian ore, thus securing practically a monopoly of the world’s chromite trade. The Chrome Co., Ltd., is controlled by French and English interests. Chalas & Sons, Finsbury Pavement House, London, E. C, are the largest stockholders. There were formerly German stockholders. L. Bernheim does not seem to be associated with the Chrome Co., Ltd., but it is said that he still owns chromite deposits in New Caledonia. Besides the operations of the Chrome Co., Ltd., there are a number of independent operations in different parts of the island. These are mainly under the control of inhabitants of the island.

—The important chromite deposits of southern Rhodesia are near the town of Selukwe, which is connected by railroad with the shipping port of Beira. They occur scattered through an area of schist and serpentine. One hundred and twenty chromite bodies have been mapped out, but the only ones that have been developed are ten closely grouped large bodies at Chrome Mine northwest of Selukwe. One of the largest bodies is 180 feet wide and 240 feet long. The ores are high grade, averaging between 48 and 51 per cent. chromic oxide.

Recently considerable publicity has been given to the discovery of what are reported to be among the largest deposits of high-grade chromite in the world in the Umvukwe Hills in the Lomagundi district 30 miles from Banket Junction, southern Rhodesia. The ore is said to occur over a large area in bodies in serpentine. More than two million tons is reported to have been uncovered. The deposits were discovered by Albert Peake, of Umvukwe Ranch, and are owned by Peake Brothers, who are said to have offered them to the Imperial government on special terms.

Chromite was mined in Rhodesia for the first time in 1905, the ore coming from claims near Selukwe held by the Bechuanaland Exploration Company, Ltd. Production steadily increased, slowly at first but more rapidly after 1910, when the Selukwe mines were taken over by the Rhodesia Chrome Mines, Ltd. In 1910 the staking of chromite claims in the Hartley district was reported and in 1911 chromite was discovered at Victoria. Shipments from Selukwe stopped in August, 1914, after the declaration of war, but began in December and increased during 1915 and 1916. In 1917 the discovery of the large and valuable deposits of chromite in the Lomagundi district (already mentioned) was reported. Previous to 1916 the entire production of Rhodesian chromite came from the Selukwe mines of the Rhodesia Chrome Mines, Ltd. In 1917, however, another company, the Rhodesia Metals Syndicate, Ltd., entered the field and is producing important amounts of ore.

—Before Turkey lost most of her European possessions after the Balkan wars, the chromite deposits of the Kossowo, Uskub, and Monastir district of Serbia and the Saloniki district of Greece were within her borders. Now, however, only the deposits of Asia Minor remain to her.

Chromite deposits are widely scattered through many parts of Asia Minor and are said to be numbered by the hundreds. The most important deposits are grouped into three districts: In the regions of Brussa and Kutahia south of the Sea of Marmora, where the important Daghardi deposits are found; near Macri, Denislu and around the Gulf of Adalia in the southwestern part of the peninsula, as well as on the neighboring Island of Rhodes; and near Mersina, Adana, Aleppo, and elsewhere in the region around the Gulf of Alexandretta northeast of the Island of Cyprus. Smaller deposits are reported in the vilayets of Angora and Kastamuni in the north central part of Asia Minor and near Beirut and Damascus in Syria. All the ore bodies are found in more or less schistose and decomposed serpentine in groups of lenslike or irregular bodies.

The chromite mines of Asia Minor have produced important quantities of ore. From about 1870, when Turkey began to supplant the United States as the world’s principal producer of chromite, to near 1900, Asia Minor furnished the bulk of the chromite for the world’s consumption. Most of the ore mined has come from the mines in the Brussa region on the south and southwest slopes of the Mysian Olympus and from the mines of the Macri region. The Brussa and Kutahia deposits are said to have produced an average of about 20,000 tons annually for many years, of which the Daghardi mine is said to have furnished nearly three-fourths. This deposit consists of high-grade ore averaging 51 to 55 per cent. chromic oxide and has been estimated to contain about 10,000,000 tons of ore. Probably this is somewhat an exaggeration, although doubtless the deposit is large and important.

The chromite mines in the Macri region have furnished a considerable part of the output of Asia Minor, but much of the ore mined in recent years has been of low grade, running as low as 40 per cent. chromic oxide. The chromite near Denislu and that near the Gulf of Adalia, on the other hand, is said to be very rich, some deposits containing ore averaging as high as 56 per cent. chromic oxide.

Most of the chromite mines of Asia Minor are probably now under the control of the Turkish government, having reverted back ten or fifteen years ago when increasing competition of New Caledonia chromite in foreign markets resulted in the shutting down of many of the mines. The taxes on both worked and undeveloped mineral properties are so heavy in Turkey that unless mines are bringing in continuous and substantial revenues, they cannot be held by private individuals.

It has been the policy of Turkey not to allow her mineral properties to fall into the hands of foreigners. Even while the exploitation of the chromite deposits was most vigorous, therefore, the mines, although in many places worked by foreign firms, were largely owned by the Turkish government or by Turkish subjects who leased them. Thus in 1904 the principal deposits near Brussa were owned by an officer of the Porte and were operated by J. W. Whittal & Co., an English firm in Constantinople, while other deposits in the same district were worked by Patterson & Canghellari, an English company located in Smyrna. The famous Daghardi deposit, in the Kutahia region, at that time was owned by the Turkish minister of marine and was operated by a Turk named Raghit Bey.

In the Macri district, a number of low-grade deposits were in 1904 under the control of Patterson & Co., of Smyrna, and the mines near the Gulf of Adalia were controlled by a French syndicate. Some large deposits near Denislu, in the interior, north of Macri, are said to be lying undeveloped owing to the refusal of the Turkish government to permit mining.

The chromite deposits in the region surrounding the Gulf of Alexandretta have been worked in a small way both by Turks and foreigners. Among operators in the region are mentioned Durian Effendi, a Turk, representing the Ottoman Bank; Husni Herikizadeh Effendi, a Turk of Adana; Nader Brothers, of Mersina; Alfred Keun & Co. of Smyrna; Protopazzi Brothers, of Smyrna, and Mavrommati & Sons, of Mersina, both probably Greek firms; Loizides, of Mersina; and Hadji Kemal Bey, of Constantinople. Durian Effendi is mentioned also as having operated chromite mines near Beirut.

The most important chromite deposits of India are in the northern part of Baluchistan, but the mines of the Madras and Mysore districts in southern India have also furnished important amounts of ore. A small production has come from Bengal. The deposits of Baluchistan are large and the ore is rich, much of it averaging nearly 55 per cent. chromic oxide. One deposit is reported to be 440 feet long by 5 feet wide. The ore bodies are segregations in serpentine. The problem of transportation is difficult, as the ores are far from the coast and land transportation facilities are poor. Nevertheless, those mines have made a steady output since they were opened in 1903. The largest production was in 1907, when the yield exceeded 7,000 tons. Since then there has been a decrease owing to competition from New Caledonia and Rhodesia.

Chromite ore bodies were exploited in Madras as early as 1861 and small amounts of ore were mined intermittently. The ores are associated with magnesite veins in serpentine. Since 1907 a steady production is recorded from Madras, which has increased recently. Important deposits of chromite are found in Mysore. These deposits have produced more than 2,000 tons of ore annually in recent years, which is reported to have been sent to the United States. The chromite deposits of Bengal are said to be small and unimportant. In Bombay a large body of low-grade chromite is said to measure 1,000 by 300 feet and to average 34 per cent. chromic oxide.

Before 1910 chromite mining in Japan was sporadic and unimportant, but since 1910 the output has been steady and increasing. The principal occurrences of chrome ore are in the southwestern part, the mines of Wakamatsu, in Hoki, being the most important. The ore is said to average about 40 per cent. chromic oxide. Chromite is also reported to occur in the northern part of Japan. The Japanese chromite deposits are small and soon exhausted.

The principal chromite deposits of Russia are in the southern part of the Ural Mountains and are associated with serpentine and soapstone. The deposits are classed under three heads: Large granular masses in serpentine, finely disseminated chromite in serpentine, and chromite sand in platinum- and gold-bearing placers. The characteristic occurrence of chromite bodies in the Urals is as segregations within areas of dunite largely altered to serpentine. Platinum in scattered grains is associated with chromite in the dunite in several places. Recently chromite deposits have been reported in the northern part of the Caucasus Mountains.

—The chromite deposits of the Balkan Peninsula may be grouped into four main districts: central Serbia; southern Serbia; Saloniki, in eastern Macedonia; and Magnesia, southern Thessaly, and the neighboring islands. The chromite deposits are found in serpentine derived from the alteration of peridotite.

The chromite mines of Serbia and Macedonia for many years furnished a small production, credited to European Turkey, which before the last Balkan War embraced all the chromite-bearing areas. Many of the deposits of central Serbia are poorly situated with reference to transportation, the ore being hauled on carts to the railroad stations and thence by rail to the coast. In eastern Macedonia some of the mines are relatively near the coast and the ore is carried on carts to Saloniki. The mines of Serbia and Macedonia were worked in part by individuals and in part by the same firms which mined the chrome ores of Asia Minor, such as Patterson & Co., Whittal & Co., and others.

The chromite mines of Magnesia, Thessaly, and adjacent islands in eastern Greece have furnished a more or less continuous output for the last 30 or 40 years. The ore mined, however, has been mainly of low grade, most of it averaging between 30 and 40 per cent. chromic oxide. It is said to be used largely for refractory purposes. Before 1908 most of the Grecian production of chromite came from the mines of Magnesia, but more recently the mines of southern Thessaly have furnished most of the ore. Mines in the Grecian Archipelago have also furnished some ore. The annual output of Greece has varied from a few hundred tons to more than 15,000 tons. During the past 20 years it has rarely fallen below 5,000 tons.

Chromiferous iron ore in considerable quantity is mined in Greece, most of it being exported. In 1913 ten or more mines were worked. The production has averaged more than 100,000 tons annually. The mines are operated in part by Greek and in part by French and British firms.

The chromic iron ores produced in the former Austrian Empire have come mainly from the central part of Bosnia, but the chromite mines in Upper Styria and those on the Roumanian border have also furnished an appreciable output, the ore being low-grade. The deposits of Bosnia are in serpentine. The ore is of good quality and has been mined for use as a furnace lining. On and near the left bank of the Danube River in the Banat, Hungary, there is an extensive area of serpentine containing chromite in bunches. The deposits have been worked to a slight extent.

—In Canada chromite-bearing areas of considerable extent are found in the southern part of the Province of Quebec, where nearly all the productive chromite mines of Canada are situated. The ore occurs in serpentine in irregular masses and pockets without definite form, that range in size up to 75 feet along the longer axis, rarely reaching 100 feet. The amount of high-grade ore in the Quebec chromite deposits is not large, but low-grade ore bodies which under normal market conditions can not be mined at a profit are numerous and of large size. The low-grade ores range in content of chromic oxide from less than 20 per cent. to 35 or 40 per cent. Nearly all the Canadian ore mined has been exported to the United States. From 1910 to 1914 the output of chrome ore from the Quebec mines was insignificant, owing to the cost of mining low-grade ores and the lack of a market for them. When the price of chromite rose late in 1914, American firms began active developments in the field, and subsequently two concentrators were built by the Mutual Chemical Co. The output of Canadian chromite, both of crude ore and concentrates, during the war period was noteworthy, the production rising from 121 long tons in 1914, to 47,035 long tons in 1916 and 43,725 long tons in 1917.

The principal American firms interested in the development of the Canadian chromite deposits during the past few years have been the Mutual Chemical Co., the Harbison-Walker Refractories Co., the Electrometallurgical Co., and the Quebec Asbestos & Chrome Co. The last-named company purchased one of the concentrators built by the Mutual Chemical Co., and has furnished a considerable output both of crude ore and concentrates. Canadian firms have also produced considerable ore.

With the close of the war and the drop in the price of chromite, the Canadian mines have been largely abandoned. It is possible, however, that some American firms that mine ore for use in their own plants may continue work on a small scale.

When the United States was the world’s principal chromite-producing country, the output came from the eastern United States and principally from Maryland. The Wood chrome mine and neighboring deposits in Baltimore and Harford counties furnished most of the production. Smaller amounts were mined in North Carolina and Pennsylvania.

The principal chromite deposits of the United States, and those that have furnished nearly all the ore produced in recent years, are in California and Oregon. Recently deposits of some extent have been found in Montana, but these have not reached the producing stage. The chromite deposits of California are for the most part grouped into four principal districts, the Klamath Mountains region of northwestern California and southwestern Oregon; the Coast Range of west central California; the Sierra Nevada range throughout a considerable part of its length; and the San Luis Obispo district of southwestern California.

The chrome ores of California and Oregon form lenses or irregular bodies in serpentine and related rocks. Many of the ore bodies are found in comparatively fresh peridotite and dunite, and the intimate relation between the chromite and the associated pyroxene or olivine is well shown. In places, also, chromite masses are found in the mantle of residual material derived from the alteration of serpentine and other rocks. Most of the chrome ores of the Pacific Coast are of low-grade, few running more than 45 per cent. chromic oxide. Concentrating plants have been built to beneficiate the ore from bodies large enough to warrant such expenditure. At some plants the grade of ore was thus raised to more than 52 per cent. Locally small bodies of high-grade ore have been found.

The chromite mines of the eastern United States were first worked about 1827 and continued to be operated for about forty years. The California deposits began to be developed about 1870, but never furnished a large output until the war raised the price of chromite to unprecedented figures and ore could be produced at a profit in spite of high costs and high freight rates to consuming centers. The chromite mines of the United States have always been worked and controlled by American capital. In California the ore has been mined mainly by private individuals working small scattered deposits. A few large firms, such as the California Chrome Co., the Adams & Maltby Co., L. H. Butcher Co., and the Union Chrome Co., worked on a larger scale during the war period.

Deposits of chromite have been known in Alaska for a number of years, but not until the war brought high prices was it possible to mine them at a profit. The deposits of present importance are near the southwestern end of the Kenai Peninsula. About 1,000 tons of ore containing 46 to 49 per cent. chromic oxide was mined in 1917.

—As far as is known, only one chromite-bearing district of importance occurs in South America, this being in the State of Bahia, in Brazil. One deposit has been worked at this locality by E. J. Lavino & Co., of Philadelphia, and the discovery of several neighboring deposits is reported. The first shipments of ore were made in February, 1918, and by July 1, 1918, 12,620 tons had been sent to the United States. The deposits are said to be owned by Newman & Co., a firm of American exporters in Bahia. They are leased to E. J. Lavino & Co., of Philadelphia.

South America, outside of Brazil, has no known chromite deposits of importance. In Colombia, chrome ore is reported to exist near Antioquia and chromiferous pig iron is said to have been produced by the blast furnace near Medellin. In Venezuela, chrome ore is said to occur on Coro Peninsula.

Important chromite deposits lie along the north coast of Cuba in the provinces of Camaguey and Oriente. A small deposit is found in the northwestern part of the Province of Matanzas. The most important deposits in Cuba are those at the Caledonia mine, south of the Bay of Nipe and northeast of the Bethlehem Steel Co.’s Mayari iron mines. These deposits are estimated to contain about 40,000 tons of ore in sight. They are owned and worked by the Bethlehem Steel Co., which began exploitation in the spring of 1918. Shipments during 1918 amounted to 8,820 tons. Next in importance to the deposits at the Caledonia mine are those along the coast, northeast of Baracoa, known as the Cayoguan and Potosi deposits, where about 35,000 tons of ore is estimated to be in sight. The deposits are on the north edge of a rugged mountain range forming the eastern end of Cuba. The Cayoguan claims are owned by Brady interests, American, and the Potosi claims by the Harbison-Walker Refractories Co., of Philadelphia.

In the Province of Camaguey the deposits are found northeast of the town of Camaguey. They consist chiefly of masses of ore in residual clay and float on the surface. The underlying rock is serpentine. The Camaguey deposits are owned in part by Lehigh University and in part by Cubans. The estimated reserves are 20,000 tons.

Exploitation of the chromite deposits of Cuba began in the fall of 1917 and continued during the spring and summer of 1918. Only the Caledonia mine has produced ore. The chromite deposits are all associated with areas of serpentine.

Chromiferous iron ores that are destined to play an important part in the American iron and steel industry are found at Mayari, Camaguey, and Moa, along the northeastern coast of Cuba. The reserves are measured in hundreds of millions of tons. Only the Mayari deposits are mined at present.

Chromite deposits were developed in the interior of Guatemala in 1917 and shipments started in the autumn. The deposits were owned and operated by the International Railways of Central America, an American company, and are situated in the hills 100 miles inland from Puerto Barrios. The ore is in serpentine. It is very pure and is especially desirable for chemical purposes. The average chromic oxide content of the shipments during 1918 was 58 per cent., thus making this the highest grade ore that came to the American market. The ore was used by the Grasselli Chemical Co. Because of the distance from the railroad, these ores are very expensive to mine, and it was only on account of the high prices paid for chromite during the war that they were developed.

The country that leads in the manufacture of chromium products, such as ferrochrome and chrome chemicals, is the United States. In normal times the United States consumes more than one-third of the annual consumption of chromite by the world. In 1913 the chromite used by manufacturers of ferrochrome and chrome chemicals in the United States amounted to 65,000 tons. Owing to the war, the consumption increased markedly until 1917, when it was nearly 130,000 tons. The normal consumption of chromite in England is about 25,000 tons and in France approximately 35,000 tons. These amounts have not greatly increased in recent years. Germany is an important producer of chromium products, normally consuming 30,000 tons of chromite annually. Russia and the former Austrian Empire used perhaps 5,000 tons each annually. Norway and Sweden use small amounts. Russia’s consumption has been mainly in the manufacture of chromium chemicals, and that of the former Austrian Empire was principally for refractory purposes. In Norway and Sweden small amounts of ferrochrome are produced.

—The United States, although the world’s largest consumer of chromite, is not an important producer of this mineral in normal times. During the 30 years preceding the war, the annual production never exceeded 4,000 long tons of crude ore, and during the last 15 years preceding the war the largest annual production was 598 long tons, in 1909. The production in 1913 was less than 1 per cent. of the domestic requirements.

The chromite supply of the United States has, therefore, come largely from foreign sources, and these sources have been mainly Asia Minor, Rhodesia, and New Caledonia. Before 1905 Turkey in Asia was the principal source of supply. Since then, however, Rhodesia and New Caledonia have largely replaced Turkey in the American chrome market.

Although numerous deposits of chromite occur in the western United States and locally in the eastern states, these deposits are usually small and scattered or of low grade. On account of their physical character, small size, scattered occurrence, or distance from consuming centers, domestic chromite could not be furnished to consumers in the required grade or for the price that chromite from rich foreign deposits could be furnished. For this reason the American chromite deposits remained undeveloped and no ore was mined except small quantities which were consumed for refractory purposes in neighboring metallurgical works.

When in 1914, at the beginning of the war, the price of chromite increased, production was immediately stimulated, this being shown by the rapid increase in output from 591 long tons of crude ore in 1914 to about 82,350 long tons of crude ore in 1918, equivalent to about 66,554 tons of ore on the basis of 50 per cent. chromic oxide. Even this largely increased domestic output, however, filled only little more than one-half of the American requirements, the total amount of chrome ore consumed in 1918 being about 104,000 long tons on the basis of 50 per cent. chromic oxide. Had the market for chromite kept up, however, the domestic mines would have supplied a much larger proportion of the requirements in 1919. The consumption of chromite in the United States in 1913 amounted to 65,000 tons of ore containing 50 per cent. chromic oxide. From this it rose to about 127,000 tons in 1917, which represents the maximum annual consumption thus far.

The following table shows the production and imports of chromite on the basis of 50 per cent. chromic oxide, from 1913 to 1918, as well as the total quantity available for consumption for these years. No chromite is exported from the United States.

Table 26.—Production and Imports of Chromite, United States, 1913-1918

The prices paid for domestic chromite in the United States in recent years ranged from an average of $11.19 per ton in 1913 to an average of about $24.00 per ton in 1917.

When the need of increased shipping was felt in the latter part of 1917, steps were taken to reduce the imports of chromite from distant countries, such as Turkey, New Caledonia, and Rhodesia, to increase the imports from nearby sources such as Brazil, Cuba, and Canada, and to urge the maximum production from domestic mines. As a result, the imports of chromite from Brazil were 17,854 long tons of crude ore and from Cuba 8,821 long tons of crude ore in 1918. The only previous production in Cuba was 34 long tons in 1916 and 17 long tons in 1917. Brazil had no production before 1918. The imports from Canada amounted to 20,949 long tons of crude ore in 1918, as compared to 19,021 long tons of crude ore in 1917, and 12,220 long tons of crude ore in 1916. In order to reduce the importation of chromite from countries far overseas, various restrictions were put into effect by the War Trade Board in the early part of 1918.

The development of domestic chromite supplies means the depletion of limited resources, high cost of production, use of lower-grade ores, and lowered efficiency in consumption. With the free access of high-grade foreign ores, the market for domestic ores, therefore, disappears; and the domestic chromite-mining industry can not survive to any large extent. If world conservation of raw materials or the best use of the world’s resources is of chief importance, the domestic chromite-mining industry should be allowed to decline, and cheaper and higher-grade foreign ores should be allowed to replace domestic chromite. Experience during the past few years has shown that the chromite deposits of the United States, supplemented by imports from Canada, Brazil, and Cuba, can largely supply the domestic requirements for a limited period.

The United States controls only a small part of the chromite reserves of the world. American firms own the principal Cuban deposits and control the Brazilian deposits through leases. The United States is, therefore, dependent to a large extent upon the good will of France and England for a continuous supply of chrome ore, these two countries jointly being largely in control of the chromite reserves of Rhodesia and New Caledonia. Turkey controls most, if not all, of the chromite deposits of Asia Minor, but because of their enclosed situation on the Mediterranean, these deposits could not be relied upon as a source of supply in time of need. The same is true of the deposits of the Ural region in Russia.

The chief chromite-consuming firms in the United States are the Electrometallurgical Co., probably the largest producer of ferrochrome in the world; the Mutual Chemical Co., and the National Electrolytic Co., large producers of chromium chemicals, and the Harbison-Walker Refractories Co., American Refractories Co., and various steel-making plants, users of chromite for refractory purposes.

—Before the war Great Britain consumed annually about 25,000 tons of chromite, most of it being used by Blackwell & Sons, Ltd., for the manufacture of ferrochrome. The ferrochrome made in England, however, is not sufficient to supply the needs of the British steel industry, and much is imported from France.

Except for unimportant occurrences in the Shetland Islands there are no chromite deposits in the British Isles, and Great Britain is therefore dependent entirely upon overseas sources of supply. British colonies, on the other hand, are rich in chromite deposits, and as long as British ships have freedom of movement on the ocean, they will have access to the more important chromite deposits of the world.

Owing to their richness and large size, the most important of all the British-controlled deposits are those of Rhodesia. Only one of many deposits in this area is being operated, and the reserves in untouched ore bodies are undoubtedly large, comparable perhaps with those of New Caledonia.

The production of the Rhodesian chrome mines has in recent years averaged in the neighborhood of 60,000 tons annually or about 35 per cent. of the world’s production, and doubtless the output could be very greatly increased if other known deposits were developed. However, even the present production is more than twice the actual chromite requirements of Great Britain. These requirements, however, do not represent the needs for metallic chromium or chromium compounds, and if France should cease to supply Great Britain with ferrochrome, a much larger amount of the raw material, chromite, would be necessary for the English steel industry.

Besides the chromite deposits of South Africa, chromite deposits of importance are found in other British colonies, notably in British India and Canada. Amounts of chromite varying from 2,000 tons to 10,000 tons have been produced annually in British India for many years, coming mainly from Baluchistan, in the northwestern part, but a small production has come also from Mysore, in the southern part. In early years, India furnished a more important part of the world’s supply of chromite than at present. Transportation is a serious difficulty in the mining of these deposits and when New Caledonian and Rhodesian ores became developed, the Indian ores dropped in importance.

The Canadian deposits, while of considerable extent, and having ready accessibility to eastern American markets, have not been extensively or continuously mined, on account of their low-grade character. By concentration, a medium high-grade product can be obtained, but concentration methods are expensive and bring the cost of the material up to such an extent that it can not compete with other ores now on the market. Thus, the cost of producing both Indian and Canadian ores is such that under normal conditions it is difficult to find a market for them, but in case of necessity, a considerable tonnage can be supplied from these sources.

Other British colonies in which deposits of chromite exist are New South Wales, Tasmania, and New Zealand. As far as known, the deposits in these countries are small and only those of the first have furnished a small production.

Besides controlling chromite deposits in many parts of the world through her colonial possessions, Great Britain controls deposits through British firms with foreign possessions. Thus, the Chrome Co., Ltd., of mixed British and French interests, controls not only the Rhodesian chromite output but also owns and controls most of the important New Caledonian mines.

Great Britain has in the past received most of her supplies of chromite from Rhodesia, New Caledonia, and Turkey. Although more than enough chromite is produced in Rhodesia to supply the British needs, England has allowed most of the Rhodesian ore to be exported to other countries and has imported foreign ore for part of her own needs. Probably the largest part of the Rhodesian output before the war went to the United States. Much of the ore consumed in England has come from Turkey, where English firms have been interested in chromite mining for many years. Most of the Indian output probably has been used in Great Britain, but a part has gone to France.

—A few deposits of chromite are known in France, but they are of no importance commercially. France, therefore, like England, is entirely dependent upon overseas sources for her chromite supply. Unlike England, however, France has only one colony, New Caledonia, containing important chromite deposits; but luckily this colony contains enough to make it one of the world’s principal sources of chromite.

Although the Chrome Co., Ltd., which controls the principal New Caledonian chromite deposits and is the largest shipper, represents both English and French capital, France through political means can control the output of chromite from the island. While in the past probably the major part of the chromite used in France has come from this source, France has also used Rhodesian and Turkish ores and probably Russian ores to a considerable extent, and much New Caledonian ore has gone to Germany, the United States and Great Britain.

The principal French firms manufacturing ferrochrome are the Société Electrometallurgique Française, at La Praz; Société La New Metallurgie, at Giffre; Société Anonyme Electrometallurgique, at Albertville; Keller, Leleux et Cie, at Livet; Société Electrometallurgique de Saint Beron, at Saint Beron; Ch. Betrolus, at Bellegarde; and Rochette Frères, at Epierre.

—Except for unimportant low-grade deposits in Silesia, Germany has no chromite supplies within her borders. As a user of chromite Germany ranks in importance with France, most of the ore consumed being used in the manufacture of ferrochrome, the principal manufacturers of which have been the Krupp works. Chrome chemicals are also made in abundance, however. None of Germany’s former colonies is known to have chromite deposits except Togoland, and the Togoland deposits are undeveloped and are believed to be unimportant.

In the past, Germany has received chromite from New Caledonia, Rhodesia, Turkey, Greece, and probably Russia. Because of the long rail haul from Russia and the poor state of development of the industry in Turkey, the ores from these two countries were, in the years immediately preceding the war, being largely replaced by ores from overseas. The four large chromite-consuming countries have, therefore, all been looking mainly to New Caledonia and Rhodesia for their sources of supply.

During the war, when overseas chromite was not available, Germany was enabled by her relations with Turkey to obtain chromite from Asia Minor, and probably from chromite mines in Serbia, Hungary, Bosnia, and Herzegovina. Thus in time of need, when the usual overseas sources of supply were cut off, Germany, through her relations with neighboring countries, was able to obtain by land sufficient chromite to supply her ordnance requirements. Had the war continued Germany would doubtless have developed the chromite resources of the Urals, and those, together with the deposits of Asia Minor, even in their present state of development, could have kept Germany supplied indefinitely.

It is probable that German control became important in the mines of Asia Minor during the war. By relatively small improvements in transportation facilities, such as building branch railroad lines to the principal deposits, the chromite mines of Asia Minor might be rejuvenated to such an extent as to enable the ores to compete with Rhodesian and New Caledonian ore and to place them again among the world’s large producers. The deposits are large and the reserves rank in importance with those of Rhodesia and New Caledonia.

—Russia is independent as far as her requirements of chromite are concerned. Out of her production of about 20,000 tons annually, the domestic industry consumes less than one-fourth and the rest is available for export to nations less favored with chromite resources.

Most of the chromite used in Russia goes into the manufacture of chrome chemicals. The Russian bichromate works at Elabouga, east of Kazan, established in 1892, have consumed about 2,000 tons of ore annually.

The political and commercial control of the principal chromite deposits of the world is summarized in the following table:

Table 27.—Political and Commercial Control of Chromite Deposits

Great Britain and France produce in their colonial possessions chromite enough for their own needs and for export, but the United States, the world’s largest consumer, must depend, except in time of extreme emergency, upon imports, mainly from New Caledonia and Rhodesia.

Various countries have from time to time played important rôles in supplying the world’s demand for chromite. One country after another has been displaced, as cheaper or better grades of chromite came into the market. At times these changes were caused by the finding of larger bodies of higher-grade ores than had previously been mined, and at other times they were caused by cheaply transported ores replacing ores inconveniently situated with reference to centers of consumption.

Thus, at the beginning of the nineteenth century and up to about 1830, the Ural Mountain region of Russia supplied the major part of the world’s requirements for chromite, which were small. About 1830, important discoveries of chromite were made in the eastern United States, particularly in Maryland, and the United States soon displaced Russia as the leading producer of chromite. After this, for many years, the United States continued to lead in chromite production until about 1870, when the domestic deposits gradually approached exhaustion and important deposits discovered in European Turkey and Asia Minor began to be extensively developed.

Asia Minor was the principal chromite-producing country from about 1870 until about the beginning of the twentieth century. The deposits continued to be worked fairly steadily on account of their richness and large size, although they were inconveniently situated with reference to transportation. Only certain deposits, such as those in the Macri and Alexandretta regions, were so near to the coast that the ore could be carried on muleback or by camel to the shipping ports. From the larger deposits, such as Daghardi, the ore had to be transported by animals to railroad stations, often a distance of many miles, and then by rail to the coast. Because of these difficulties, Turkish ore was largely replaced by ore from the important New Caledonian and Rhodesian deposits as soon as those were developed.

In New Caledonia labor is cheap and the deposits are all near the coast. By means of sailing vessels and tramp steamers which charge low rates and often require such heavy materials as chromite for ballast, this ore can be delivered to points of consumption at a relatively small cost. The Rhodesian chromite deposits are not as accessible from the coast, but they are large and rich and the rail freight rates to the shipping port are exceptionally low. For this reason, Rhodesian ore has been able to successfully compete in the market with New Caledonian ore, and these two sources have, therefore, in recent years, jointly supplied most of the requirements of the principal nations for chromite.

During the war, because of abnormal conditions arising from the shortage of shipping facilities, there was considerable uncertainty as to whether it would be possible to supply American consumers of chromite with imported ores. Under the stimulus of much higher prices, the production of chromite in the United States increased from 255 long tons of crude chromite in 1913, to about 82,350 tons in 1918, mainly from California, Washington and Oregon. This production was larger than the annual production of crude ore from any single source (except 82,910 tons from New Caledonia in 1906) since the chromite-mining industry began. This production, of course, could not be continued without a rapid depletion of American chromite reserves, and does not represent a normal development.

Nickel is used chiefly in the manufacture of special steels. It is estimated[65] that about 60 per cent. of the entire nickel production goes into steel making in normal times and more under war conditions. Nickel steels are the most important of all the alloy steels and are the most used.[66] They are used where unusual tensile strength is required. Nickel-chromium steels are used in the manufacture of armor plate.

Ordinary nickel steels commonly carry about 3¹⁄₂ per cent. nickel. “Highly nickeliferous steels carrying up to 40 per cent. nickel are used for special purposes where non-magnetic qualities, resistance to corrosion and, above all, no expansion or contraction, or any desired expansion or contraction, with change of temperature, is important.”[67]

Non-ferrous nickel alloys have found extensive uses, and probably about 20 per cent. of the world’s production of nickel goes into them. By far the most important are those formed from nickel and copper. One, generally known as “cupro-nickel,” contains approximately 80 per cent. copper and 20 per cent. nickel and is used largely for bullet jackets and other munition purposes. Another, which has become well known under the trade name “Monel metal,” contains 29 per cent. copper, 67 per cent. nickel, about 2.5 per cent. iron, and a small amount of manganese. It is manufactured direct from the Sudbury matte. Monel metal is used chiefly where a strong non-corroding metal is needed, as, notably, in ship propellers.

It is estimated that about 2 per cent. of the nickel production is used for electro-plating. To a large extent nickel plating prevents corrosion of the metal plated.

Nickel is also used for storage batteries; for coinage; as a catalyser in the hardening of oils or fats (solid fats being used for soap making); for cooking utensils; and as a pigment for coloring ceramic ware. It is doubtful whether these last-named uses would take more than 3 per cent. of the world’s nickel production.

Copper gives to steel properties somewhat similar to those given by nickel, notably increasing the tensile strength. Silicon also imparts similar properties to steel, increasing especially the toughness and tensile strength. A considerable proportion of chromium makes steel highly non-corroding. There is, however, nothing known that will take the place of nickel in special steels having a zero or a predetermined coefficient of expansion, such as “invar” or “platinite.”

Nickel possesses extraordinary power in giving its white color to alloys of copper; hence its use in coinage. The other white metals that might be used in its place are less plentiful and more expensive. There is no other abundant metal or alloy having the good color, great strength and resistance to corrosion possessed by Monel metal and like alloys of nickel and copper.

Nickel salts are used as substitutes for metals of the platinum group as catalysts in hardening oils and fats.

Production of nickel on a fairly large scale did not begin until the mines of New Caledonia were opened in 1875. To handle these ores, smelters and refineries were built in England and continental Europe. As the ores are of the silicate type and free from copper, they were easily treated by common processes of smelting with fluxes to get rid of the gangue and then heating with charcoal for reduction to a metallic condition. A pure metal was obtained which found a good market.

Production of nickel-copper ores in the Sudbury district began in 1887. On account of the copper with the nickel in these ores, new processes of refining had to be worked out and the trade prejudice against the product had to be overcome. This took persistent effort for several years. Only one of the first companies to operate in the Sudbury district has survived to the present time. This is the Canadian Copper Co., the producing subsidiary of the International Nickel Co.

Three new refining processes have been developed to handle nickel-copper ores. The Orford Copper Co. (subsidiary of the International company) uses the salt cake process. This process is one of fusion with sodium sulphide, the copper sulphide concentrating on top and the nickel sulphides at the bottom of the melt. Repeated fusion of the “tops” and “bottoms” effects a good separation.

The Mond company had a process before it had any mines. This process depends upon volatilization of the nickel by passing carbon monoxide over the matte, which has been previously roasted and leached of its copper content. Nickel carbonyl, Ni(CO)₄, is formed and metallic nickel is thrown down by decomposition of this product, so that the nickel obtained is pure.

The Hybinette process, a process depending on electrolysis, was first worked out at the plant of the Orford Copper Co. on Sudbury matte. It was used for low-grade ores at Fredericktown, Mo., and then later for the Norwegian ores at Kristiansand. It is to be used in the new refinery of the British-American Co. in Ontario.

Monel metal is made directly from Sudbury matte with the removal of a little of the copper. It is known as a natural alloy, in contrast to one made by combining the pure metals.

Increased use of nickeliferous iron ore for steel making will decrease the amount of nickel that will have to be added in making such steel. This will probably be overbalanced by the increased use of such steels.

Analyses of igneous rocks indicate that nickel is present in the average igneous rock to the extent of 0.020[68] per cent. Of its occurrence, Clarke says:[69] “Very frequently detected in igneous rocks, probably as a constituent of olivine. * * * The presence of nickel is especially characteristic of magnesian igneous rocks, and it is generally associated in them with chromium.” Regarding copper he says: “Minute traces of this metal are often detected in igneous rocks, although they are rarely determined quantitatively.” It is estimated[70] that copper is present in the average igneous rock to the proportion of about 0.010 per cent., or only about half that of nickel, and that zinc and lead are present in even smaller proportion. Notwithstanding this greater abundance of nickel, the workable deposits of copper, lead, and zinc are much more widespread and production is correspondingly greater. “It can thus be said that nickel is less amenable to concentration by the agencies that tend to produce workable deposits than are the other metals mentioned (copper, lead and zinc).”[71]

One would infer from the above that nickel deposits of consequence would most likely occur in connection with igneous rocks, especially those that are basic. This is indeed true; in fact, the only known nickel deposits of commercial or prospective commercial value occur in association with basic igneous rocks. The nickeliferous metallographic provinces of the world may be said to lie within petrographic provinces. Harker says:[72] “An examination of the rocks belonging to one great period of igneous activity, and of their actual distribution, enables us to distinguish areas of greater or less extent, within which the rocks present a less or greater degree of consanguinity, the law being that more marked specialization goes with narrower localization.” On the basis of this law and the fact noted by Clarke and mentioned above, nickeliferous metallographic provinces may be limited more closely than simply to areas of basic igneous rocks. They may be said to roughly coincide with areas of basic igneous rock characterized by minerals of the olivine group, these minerals having formed as a result of the high magnesium content of the rock magma.

Nickel ores occur where there was an unusual segregation of the element in the igneous rock at the time of solidification. In some places further concentration by weathering has been necessary to make an ore of the rock. In still other places, the concentration by weathering has not been sufficient to make the nickel valuable in itself, but has raised the iron content of the rock, and with it the nickel content, to such an extent as to make the ore valuable in the first instance as an iron ore and of additional value because of its nickel content.

Nickel is unique among the less rare metals in that a single district contains a quantity of accessible, workable ore, far ahead of that in all other known deposits of the world combined. This is the Sudbury district of Ontario. The nickel ores there were segregated from an enormous mass of igneous rock intruded under conditions favorable for broad segregation and subsequently so eroded that large ore bodies are accessible.

In those nickel ores and nickeliferous iron ores where weathering has been a necessary agent in concentrating the nickel and iron enough to make them commercially valuable, the original deposits were nickeliferous igneous rocks—that is, they were similar to the rocks associated with the nickel deposits of the sulphide type, but contained much less nickel. The nickel-ore deposits of the New Caledonia region, which rank next in productiveness to those of the Sudbury district, are of this type. The Cuban nickeliferous iron ores best exemplify iron ore deposits of this type.

The nickeliferous ore deposits of the world may be divided into two main types—the sulphide type, in which weathering has not been of prime importance, and the garnierite or lateritic type, in which weathering has altered and concentrated the nickel as well as the chromium and iron of the original rock. In addition, nickel occurs in some places with ores of precious and semi-precious metals in veins. Nickel may be recovered from such ores as a by-product, but the ores are never mined primarily for their nickel content. The brief descriptions of the known deposits, grouped according to type, which follow, have been taken from the descriptions of the world’s nickel deposits in the report of the Royal Ontario Nickel Commission. A few direct quotations from the text of the report are given.

—The Sudbury district is situated in southeastern Ontario, Canada. In its broader outlines the geology of this district is relatively simple. An immense mass of nickeliferous rock was intruded as a “laccolithic sheet” or sill along an unconformable plane of contact between flat-lying sediments and an underlying complex of ancient rocks. During the intrusion and cooling, or perhaps soon thereafter, the underlying rocks of the central part of the laccolith, covering the reservoirs from which the magma came, subsided. Long periods of erosion then planed down the region until all that is left of the sill occupies a synclinal basin nearly 40 miles long and 10 to 15 miles wide. All of the rocks involved are of pre-Cambrian age.

The laccolithic sheet is approximately 10,000 feet thick. It differentiated on cooling into two kinds of rock—micropegmatite, a rock of the granite group, now forming the upper part of the sill, and norite, a gabbro rock, the lower part. The gradation between these two rocks is rather abrupt. At the bottom of the sill, in some places lying between the norite and the underlying rock and at other places entirely within the underlying rock, are bodies of ore consisting of pyrrhotite, pentlandite and chalcopyrite. These are segregated products of the norite, which in some places solidified at the base of the sill and in others were intruded as dikes in the underlying rocks or in previously solidified portions of the norite. They constitute commercial ore bodies where the sulphides form a preponderant part of the rock.

The ore bodies are classified as “marginal” and “offset.” The marginal deposits occur along the contact of the norite with the underlying rock. Frequently they lie entirely within the rocks adjacent to the norite. The offset deposits occur where faults cut across the limbs of the fold, forming zones of weakness into which ore or mineralized norite was intruded.

The nickel-bearing mineral is pentlandite; the copper-bearing, chalcopyrite. The other sulphide, pyrrhotite, is a sulphide of iron. The ores mined to date average roughly 3.5 per cent. nickel and 2 per cent. copper.

From the opening of the district in 1887 to the end of 1916 nearly ten and one-half million tons of Sudbury ore had been mined and smelted; and, from this, about 285,000 tons of nickel had been produced. It is estimated that there are probably fully 100,000,000 tons of ore reserves. Over a million and a half tons of ore were mined and smelted in 1916.

The Alexo Mine is situated 150 miles due north of Sudbury. The ore occurs at the contact of a large mass of peridotite (now altered to serpentine), with a pillow-lava which the peridotite intruded. The ore consists of sulphide minerals segregated from the intrusive mass. It is of two types, one, a massive, pure sulphide occupying cracks in dike-like relationship, the other, disseminated sulphide in peridotite adjacent to the sulphide ore masses. The ore deposit has a proven length of 700 feet, has been opened to a depth of 120 feet, and drilling has shown ore to extend to a depth of 240 feet. The average width may be taken as approximately 10 feet. By the end of 1916, ore had been raised to the extent of 34,650 tons and more than that amount had been developed. About 12,000 tons of ore were shipped in 1915, averaging about 4.9 per cent. nickel and 0.6 per cent. copper. Several hundred thousand tons are probably available in this deposit.

The nickel ore deposits of Norway are similar mineralogically to those of Sudbury. The deposits are small, their metal content is low, and compared to the Sudbury and New Caledonia deposits they are of little consequence. Up to 1909 there had been mined and smelted in Norway about 400,000 tons of nickel ore. The hand-sorted ore carried 1.4 to 1.7 per cent. of nickel.

Deposits like those of Norway have been found in Sweden, but they have not been worked in recent years. There is evidently a nickeliferous metallographic province in the Scandinavian countries and important ore deposits may yet be found there.

In the United States, near Gap, Lancaster County, Pennsylvania, is a deposit of nickel ore of the sulphide type, which occurs as a segregation from a 300-ft. dike of amphibolite. It was worked spasmodically for copper throughout the 18th century. Nickel was discovered in the ore in 1852 and 4,000,000 pounds of nickel are estimated to have been produced up to 1882. The advent of New Caledonia and Sudbury ores caused the closing of the mine. The ore as mined carried 1 to 3 per cent. nickel and about one-third as much copper.

Near Julian, San Diego County, California, is a sulphide nickel deposit that has never been commercially productive. Assays show the ore to contain nearly 3 per cent. nickel or more.

A small deposit in Tasmania has produced a few thousand tons of rich ore. Diamond drilling has shown that little ore remains.

Nickel-copper sulphides have been found in connection with a large intrusive of basic igneous rock in the Insizwa Range, South Africa. No payable ore has been found.

Nickel sulphide deposits of unknown importance occur in India and in Southwestern China. Small deposits which were worked when nickel was scarce occur in Italy, Scotland, Germany and Austria.

—About one-third of the surface of the island of New Caledonia is occupied by serpentine, this being the weathered product of basic igneous rock. “The ore, noumeaite or garnierite, occurs as a hydrated silicate of nickel and magnesia and may best be described as an alteration product of the serpentine in which the magnesia and iron have been replaced by nickel. * * * The workable deposits always occur on the saddle of spurs from the main mountain ridge, at elevations of 400 to 2,500 feet, the latter elevation being the more common. * * * The replacement of the serpentine by nickel follows the joints and fractures in the serpentine and the undecomposed blocks and boulders of serpentine are as a rule covered by a shell of ore which has to be picked off.” The ores are hand picked to bring them up to a grade profitable to treat. In the past it has not been considered economical to smelt ore of lower grade than 4.5 per cent. nickel nor to ship ore much below 6.5 per cent.

The ore bodies usually contain under 250,000 tons of ore. The largest mine yet worked produced less than 600,000 metric tons (2,204 lb.) of ore. Probably there still remains as much undeveloped ore as has been mined in the forty years of production,—equivalent to 160,000 tons of nickel. This would be equal to about four years’ output of the Sudbury district at the 1916 rate of production. “There are large bodies of lower-grade ores which it has not yet been found feasible to treat.”

Three large blanket deposits of nickeliferous iron ore occur on elevated plateaus in Cuba. These are typical lateritic (residual) deposits. The average depth of the ore is 15 feet and the combined tonnage of the three deposits is placed at one and one-half to three billion tons. The nickel content ranges from about 0.6 per cent. to 2.1 per cent. and shows progressive enrichment from the top downward. Chromium is also present and shows similar enrichment. The presence of nickel and chromium in the iron ores greatly enhances their value for making special steels.

Iron ore on the island of Seboekoe, lying off the southeast coast of Borneo, contains appreciable amounts of nickel and chromium. At least 300,000,000 tons of ore are contained in the deposit, which is a porous limonite, about 15 feet thick, overlying serpentine.

In the United States, nickel deposits of the garnierite type occur in North Carolina and Oregon. Attempts to mine these ores have never been successful.

Small nickel deposits of the garnierite type occur in Egypt, Germany (Prussian Silesia), Greece, Madagascar, Russia and Spain. Nickeliferous iron ores occur in Greece, and it is thought that chromiferous iron ores on Mindao Island, in the Philippines, may, on further exploration, prove to be nickeliferous.

—Nickel occurs with other metals, precious or semi-precious, in some vein deposits and is recovered as a by-product in the treatment of ores from them. It is notably present in the deposits at Cobalt, Ontario, and has been found in vein deposits in the United States, France, Germany, Austria, Mexico and South America. Several hundred tons are recovered annually in the refining of copper produced in the United States.

Related to the vein deposit type of nickel-bearing ore are the galena deposits disseminated through dolomite in southeastern Missouri. Iron, copper, nickel, and cobalt sulphides occur with the galena. Years ago nickel was recovered electrolytically from matte from these ores.

In 1900 New Caledonia supplied 65 per cent. of the world’s production and Ontario 35 per cent. Since then the world’s production has increased six-fold, and Ontario, by the end of 1916, was producing 80 per cent. of the whole. This shows the trend of the industry. Recent discoveries of ore in the Sudbury district and construction of new smelters and refineries in Ontario to treat the ores indicate an increasing dominance of the industry by that district. New Caledonia has not the large ore bodies and is too far away to compete favorably with Ontario, though work will continue there.

Fig. 7.—Refined nickel produced from the ores of New Caledonia and Ontario, for five-year periods; the amounts are for the calendar year indicated.

Statistics of production and ore reserves in Ontario and New Caledonia are shown graphically in figures 7 and 8.

Isolated nickel ore bodies of the sulphide type—that is, segregations from basic igneous rocks, as at Sudbury—have been found in a number of widely separated places. There is a distinct probability that others exist and may be discovered. Such undiscovered deposits might even contain more accessible ore, in the aggregate, than the total of the mined and unmined ores of the Sudbury district, but in the light of present knowledge this seems a remote possibility.

Other deposits of the New Caledonian and Cuban types will probably be discovered, but it is doubtful if as large deposits of those types remain to be found. In these the nickel has remained in the material left as residuum from the partial or complete weathering by solution of the original nickeliferous rock. This material lies at the surface and covers relatively broad areas. Bodies of it are therefore not usually difficult of discovery. They seem to be found most abundantly in warm latitudes, where solution weathering has most easily gone on under conditions favorable for preservation of the residuum.

Fig. 8.—Nickel production, and nickel content of reserves, in Ontario, New Caledonia, and Norway.

The present known nickel and nickeliferous iron-ore deposits indicate roughly the locations of perhaps all or nearly all of the nickeliferous metallographic provinces of the world. It is in these provinces that new deposits are most likely to be found. The wide-spread distribution of these provinces is indicated by the following statement in the Report of the Ontario Nickel Commission:

It is thought probable that the nickeliferous metallographic province of eastern Canada, which includes the Sudbury district, contains the greatest unknown nickel deposits, just as it contains the greatest known one, and this for three reasons. The first and most obvious reason is that the great nickel-ore bodies of the Sudbury district, the isolated Alexo ore body, 150 miles north of the district, and the appreciable content of nickel in the veins of the Cobalt and other districts near by, indicate an unusually large nickel content in the original magma from which the basic igneous rocks were derived. The second reason is that the mantle of glacial drift effectively conceals large areas of underlying rock and prevents easy discovery. The third is that the wild and unsettled nature of the country inhibits the human activities whereby accidental or other discoveries would be made.

The Sudbury nickel deposits and the Alexo ore body in eastern Ontario are under the political control of the British Empire; the New Caledonian nickel deposits are controlled politically by France, New Caledonia being a French colony; and the nickel deposits of Norway and Cuba are under the political control of those governments. The other deposits of the world, as has been noted, are commercially unimportant.

Ownership of mines and undeveloped ore bodies in the Sudbury district is divided between British and American interests. There are two companies producing ore at the present time and a third is expected to begin producing soon.

The first large company in the field was the Canadian Copper Co. This is a subsidiary of the International Nickel Co., over 90 per cent. of the stock of which is held in the United States. The Canadian Copper Co. owns the following mines: Copper Cliff, Evans, Stobie, Crean Hill, Vermilion, Creighton, No. 1, No. 2, No. 3, No. 4, No. 5, and No. 6. Four of these were being worked in 1917—the Crean Hill, Vermilion, Creighton and No. 2. In December, 1916, the president of the Canadian Copper Co. gave the following estimates of reserves of payable ore in three properties of that company: 10,000,000 tons in the Creighton; 2,000,000 tons in Crean Hill; and 45,000,000 tons in No. 3.

The Mond Nickel Co. is controlled by British interests. It owns the following mines: Garson, Worthington, Levack, Victoria and Kirkwood. The Levack has proven reserves of good ore amounting to 4,500,000 tons. The reserves of the other mines are not given.

The British-America Nickel Corporation, Ltd., has $20,000,000 of common stock, of which $14,500,000 is held by the British government in the name of Alan Anderson, trustee. By the end of 1916, this company had 11,000,000 tons of workable ore blocked out. Its mines are the Murray, Gertrude, Elsie, Blue Lake and Frood Extension. The reserves of the Murray alone are put at 9,000,000 tons.

In the southeastern part of the district an ore body 7,500 feet long, 10 to 120 feet thick, and extending to a depth of 1,020 feet in one place at least, has been found recently in diamond drilling operations by the E. J. Longyear Co., of Minneapolis. This company and its associates, all American, control the ore body. The ore tonnage of this deposit is estimated at 6,000,000 tons above the 500-ft. level. A few drill holes have gone to greater depths and found ore. It is not possible to estimate the reserves of this deposit below the 500-ft. depth.

The Alexo Mining Co. Ltd., which is mining the Alexo ore deposit north of the Sudbury district, is a Canadian concern. An estimate of the quantity of ore in this deposit is not available, but the deposit is small compared to that of the Sudbury district. The total may be several hundred thousand tons.

La Société le Nickel was under control of the Rothschilds of France at the time of the discovery of the Sudbury deposits. Mr. F. E. Merry, an English metallurgist, in testifying to the Ontario Nickel Commission, reported that Germans were in control of the company at the outbreak of the war. The German firm of Krupp had also acquired some nickel property in New Caledonia.

The International Nickel Co., the second largest holder of New Caledonian nickel lands, is the same American firm which owns the Canadian Copper Co.

Les Hauts-Fourneaux de Noumea is owned, at least since the outbreak of the war, by French interests.

According to Mr. Merry, the nickel mines and smelters of Norway were also mainly in control of the same German group that had gotten control of Le Nickel. It worked under the name “Metallgesellschaft.” One mine and smelter reopened recently were under English control.

The nickeliferous iron ores of Cuba are owned entirely by American companies, principally by steel manufacturing companies, notably the Bethlehem Steel Co.

All three companies producing or about to produce nickel in the Sudbury district own their own smelting and refining plants. The International has been smelting its ore in Canada and refining it in the United States. It has a new refinery at Port Colborne, Ontario. The Mond Nickel Co. which smelts in Canada and refines in England, has started a refinery in Canada. The British-American Nickel Corporation has built both a smelter and a refinery in Canada.

The United States Nickel Co. operates a refinery at New Brunswick, New Jersey. Les Hauts-Fourneaux de Noumea and this company belong to the same interests. They have a smelter at Noumea, New Caledonia; also a refinery at Havre, France.

La Société le Nickel has a smelter at Thio, New Caledonia, and refineries at Havre, France, and Erdington and Kirkintilloch, British Isles.

No one refining process dominates the nickel industry of the world. The two companies producing nickel from Sudbury ores are using entirely different refining processes, which they individually control; and the British-America concern, soon to begin producing, will use a third process, the Hybinette, an electrolytic process on which it has exclusive rights for North America. The Orford Copper Co., subsidiary of the International, uses what is known as the “salt-cake” process, but it also produces some nickel electrolytically.

The process of the United States Nickel Co. at New Brunswick, New Jersey, being one of fluxing and reducing from matte produced at the Noumea smelter, is not adaptable to copper-bearing sulphide ores.

The ores produced in Norway are smelted and refined in Norway by the Hybinette process.

Obviously the nickel resources of the world are controlled by a few companies. The chief one is the International Nickel Co., which has the largest holdings at Sudbury, and the second largest holdings in New Caledonia. The Mond and the British-America are the next most important, and La Société le Nickel is fourth in importance. E. J. Longyear Co. and associates do not aspire to become producers of nickel and are in the market to sell their properties. For a new concern to succeed it would have to develop a refining process of its own. The alternative would be for it to sell out to or merge itself with a firm that controls a refining process. There are no custom smelters or refineries in America. The Mond company buys the Alexo ore because its high magnesium content makes it a good fluxing material in smelting Sudbury ores.

—Though the United States has insignificant deposits of nickel ore and therefore exerts little or no political control over nickel mining, American capital plays an important if not the leading rôle in the industry. Of the four companies holding the deposits of the Sudbury district two are American, and these two possess what are doubtless the largest reserves there. One of these, the International Nickel Co., has the next to the largest holdings in New Caledonia.

—Of all nations Great Britain is in the strongest position politically with respect to the nickel industry, because of the Sudbury district being in Canada. It has used this control in an endeavor to localize the business of refining Ontario nickel ores in Canada, with the result that the International Nickel Co. is to transfer its refining operations from New Jersey to its new refinery in Ontario.

Commercially, British capital controls the two other companies having holdings at Sudbury. In one of these,—the British-America Nickel Corporation,—the government itself has a controlling interest.

The policy of the British government with relation to the Sudbury nickel ores, which give the British an overwhelmingly dominant political control over the world’s nickel, is highly significant as showing that the government is aware of the necessity for commercial as well as political control, in order to reap all the commercial and strategic advantages of its good fortune. During the war, and before the United States entered, great feeling was roused in Canada and England by the German submarine, Deutschland, loading at New York a cargo that consisted partly of metallic nickel, it being assumed that this was originally Canadian nickel. The direct participation of the British government in the Sudbury industry in such a way as to make the government practically the dominant factor, and the transfer of the refinery operations of the American-owned International Nickel Co. from New Jersey to Ontario, mark a vigorous and aggressive nationalistic policy which has attained its object without much delay.

—France owns the island of New Caledonia and has political control of the nickel deposits there. Two of the three principal companies holding New Caledonian ore deposits are presumably held by French interests. The larger one, La Société le Nickel, was for a long time controlled by the Rothschilds of France. It was reported later to have gotten into German hands.

—Germany exercises political control over no important nickel deposits. Before the war the German firm of Krupp had obtained some New Caledonian nickel properties. A German group, the Metallgesellschaft, is reported to have had control of La Société le Nickel at the outbreak of the war, and also the mines and smelters of Norway.

The essential uses of tungsten are as an alloy in high-speed tool steel, for the making of filaments for incandescent lamps, for targets and cathodes of Roentgen (“X”) ray tubes, and for electric contacts for explosion engines or wherever an intermittent electric contact is needed. Other uses are in saw and some other steels, as a constituent of stellite, in a tungsten-iron alloy for valves in automobile and airplane engines, for kenotrons and similar instruments, in a manganese-chromium-tungsten-iron alloy for wire-drawing dies, in wire cloth, luminescent screens for Roentgen (“X”) rays, mordants and minor chemicals.

—The use of tungsten in high-speed steels is as standard as the use of yeast in bread, and, though assiduously sought, no substitute is known that satisfactorily takes its place. According to report, in England and France molybdenum has been used to replace about half of the tungsten in some high-speed tool steels, but this is seemingly not a preferred method, being used only when the obtaining of tungsten is difficult. In the United States the practice has had few sponsors. The following quotation from the Mining Journal (London) for May 25, 1918, p. 318, shows that this sentiment is not unknown abroad:

During 1917, 104 (metric?) tons of molybdenite was shipped from Norway to Germany, where it probably was used as in Sweden. Henry E. Wood reported finding molybdenum in the steel of a German helmet. When tungsten was at the excessively high price of early 1916, many experiments were made to find a substitute, but apparently without full success, although lately several substitute steels containing cobalt and chromium and especially intended for cast milling-cutters and other multiple-edged tools have been placed on the market and a cobalt-chromium-molybdenum steel and a uranium steel have been offered for lathe tools. Stellite, the cobalt-chromium-tungsten alloy, in which there is only one-third to one-half as much tungsten as is used in high-speed steel, has grown in favor, and cooperite, a nickel-zirconium alloy, is also a competitor, but the trade in the combined list has made no appreciable impression on the demand for tungsten steels.

A change in the manner of using tungsten steel, by which a thin plate of high-speed steel is cemented to a more ordinary steel bar so as to form the cutting edge of a lathe tool, has made the demand for tungsten less than it would have been had the old practice been followed of making the whole tool of high-speed steel.

No startling changes of practice in the metallurgy of tungsten are known to have taken place, but there has been a steady betterment of the art, improvement in the quality of ferrotungsten, a shifting in localities of reduction, and a considerable change in the manner of use. The wasteful, lazy demand for ores of high concentration and of great purity common before the war has given way before more enlightened and intelligent practice, until firms both in this country and in England make a specialty of using low-grade or impure ores, though seemingly much more advance has been made here than abroad. One firm, the Chemical Products Co. (Washington, D. C.) was organized specifically to buy ores carrying less than the 60 per cent. tungsten trioxide (WO₃) demanded by other American firms, and ores containing sulphur, copper, arsenic, bismuth, tin, antimony, phosphorus, or other impurities to which most users objected. Two firms, the Black Metal Reduction Co., and the Tungsten Products Co., both of Boulder, Colorado, were organized to handle materials such as tailings carrying as little as 1 per cent. tungsten trioxide, and they said that they were able to pay for gold and silver in the ore.

Several firms make tungsten trioxide or tungstic acid (H₂WO₄) for ferrotungsten makers. Firms have also made artificial scheelite (CaWO₄) for the same trade, using off-color ores in the process. Powdered ferrotungsten made by chemically precipitating an iron tungsten salt from solution and reducing it to a metallic powder carrying 4 to 11 per cent. iron has been produced by several firms and seems to have started a demand for powdered ferrotungsten, so that firms are now finely grinding the massive ferrotungsten. Claims for better furnace practice which greatly cuts down the consumption of current and makes a saving of 90 to 96 per cent. instead of the usual 80 per cent. are also made. Several firms are making ferrotungsten powder and tungsten powder in iron tubes or other iron containers instead of in the graphite crucibles used before the war.

In the milling of tungsten ores, the tendency in this country is to get away from the uneconomic method of making concentrates very high in tungsten trioxide (carrying more than 60 per cent. WO₃). Few operators really know what the heads run, and the determination of losses is mere guesswork. Some of the most careful operators in the Boulder field before closing down at the beginning of 1919 were making a high-grade product carrying nearer 50 per cent. than 60 per cent. tungsten trioxide, and a lower grade product carrying about 20 per cent. tungsten trioxide, not attempting to raise its tenor. This practice cuts down the losses largely. When the great shortage of tungsten ore came in 1916, users were compelled to take lower grade concentrates, and some improved their metallurgy accordingly. This change has made the sale of 50 per cent. concentrates easier. Even in England, 60 to 65 per cent. ores were accepted where formerly a content of 67.5 per cent. or 70 per cent. WO₃ was demanded.

Formerly scheelite sold 50 cents per unit below other tungsten minerals, even though freer from bothersome impurities, but with the graduation from rule-of-thumb methods to more thoughtful, careful and scientific practice, it came to command a premium. Huebnerite seems to be still sold with and as “wolfram” in England, but in this country it must be sold according to its composition, for to most metallurgists the manganese is undesirable, though at least one firm now makes ferrotungsten from huebnerite without prejudice or difficulty. This growth in knowledge and technique has caused the price of the tungsten minerals to rank about as follows in the order named: Scheelite, ferberite, wolframite and huebnerite. This applies to tungsten used in the manufacture of tungsten and ferrotungsten for steel making. Scheelite is not wanted in this country for making filaments.

Before the war the United States imported considerable quantities of German ferrotungsten, but metallurgists claim that the ferrotungsten now made in this country is superior to any from Germany. For the present, of course, the German export trade is dead. England, formerly a small producer, is now making large quantities of ferrotungsten and tungsten powder at a number of plants. One of the producers, the High Speed Steel Alloys, Ltd., Widnes, near Liverpool, “is under government assistance and is owned by 31 of the leading consumers of Sheffield.”[75] The article quoted stated that the output was at the rate of 500 tons of tungsten per annum. The Thermo-Electric Ore Reduction Corporation,[76] Luton, was at the same time producing 140 tons of tungsten per month. The ferro produced carried 80 per cent. and the powder 98 per cent. of metallic tungsten. Only one company in the United States was producing as much as 60 tons of tungsten per month during the same war period. The Thermo Electric Ore Reduction Corporation owned mines from which it expected to produce each year 4,000 long tons of concentrates carrying 65 per cent. tungstic oxide. There are at least seven other manufacturers of tungsten or ferrotungsten in England.

France had a number of ferrotungsten plants before the war, and these are thought to be still in operation.

At the beginning of the war about half of the tungsten used in the United States was introduced into steel in the form of ferrotungsten and about half in the form of tungsten powder. This practice has changed, so that now more than three-fourths of the tungsten used is introduced as ferrotungsten, largely, it seems, because of the ferro being now manufactured in purer form and partly because tungsten powder could not be obtained for a while. At one time tungsten ores were put in the charge and the tungsten alloyed directly with the steel; in fact, tungsten steels were first made in this way, although the process was patented in this country as new. The practice seems to have been dropped because of the introduction into the steel of impurities that may be eliminated when tungsten or ferrotungsten is made first.

In the making of tungsten steels a considerable change has taken place through the increased use of the electric furnace. One considerable producer, the Latrobe Electric Steel Co., makes all of its high-speed tool steel in this way. The Vanadium Alloys Steel Co., one of the larger producers, makes a large part of its steel in the electric furnace, and the Crucible Steel Co. and some other steel companies are understood to make a part or all of their steels thus.

The removal of tin, copper and other impurities from ferrotungsten by grinding and chemical treatment has made possible the use of impure ores in the production of high-grade ferrotungsten in the electric furnace.

Tungsten, even more than tin, is found almost exclusively with granitic rocks. In a few places tungsten ores are found in volcanic, sedimentary or metamorphic rocks, but as is postulated with certain tin deposits, many of these deposits may be explained on the supposition that they are not far vertically above underlying granite.

Among the deposits themselves there is a considerable variety of types, and they may be classed as follows: Segregation deposits, pegmatite dikes, veins, replacement deposits, contact metamorphic deposits and placers.

Segregation deposits are few and of little importance and constitute those deposits in which wolframite is segregated in granite, like biotite or hornblende. A closely related type is the occurrence of tungsten minerals in aplitic granite, and this grades almost insensibly into the second type, the pegmatites.

The pegmatites are also of comparatively small importance, but do yield certain quantities of tungsten minerals. The pegmatites also grade into the next type, the veins, which have heretofore furnished the greater part of the tungsten minerals of the world. Closely connected with the veins are the fourth type, replacement deposits, in which the country rocks alongside the veins, though the veins may be very small, are replaced by various minerals, including those of tungsten. The only known large examples are the wolframite deposits near Lead, South Dakota, which were considerable producers under the high prices of the Great War.

Among the replacement deposits are to be noted also such deposits as those in the Deep Creek Mountains, Utah, in which solutions following cracks in monzonite have replaced the rock with a mass of feldspar, quartz, tourmaline, apatite, scheelite, wolframite (very little), bismuth, copper, and molybdenum minerals, which under other conditions would be unhesitatingly called pegmatite.

Closely related to the replacement deposits are the contact metamorphic deposits, the fifth type. These only recently have begun to be of commercial importance, but promise to be among the greatest, if not the greatest, producers of this country and possibly of other countries. They are of the familiar kind—limestones or limey rocks which have been invaded by granites bringing large quantities of watery or gaseous solutions of silicon, iron, aluminum and magnesium, with less chlorine, fluorine, potash and sulphur, and, in this case, tungsten. In the Great Basin broad areas of limestone, extending from northwestern Utah to the Sierra Nevadas and around their southern extremity, have been thus intruded and metamorphosed. Some large deposits of scheelite have already been exploited in the region and others remain to be worked. Similar deposits occur in Korea, Japan and Tasmania, and probably exist, though as yet undiscovered, in China, the Malay Peninsula and other countries. The tungsten mineral in such deposits is invariably scheelite.

Placers, the sixth type, are formed from all grades of deposits, but their value depends largely on local conditions. They are both residual and fluviatile deposits and have been large producers of tungsten minerals, especially of wolframite. A very large proportion of the Burmese output has been from semi-residual and stream placers, and the Chinese output in 1918, the largest ever made by any country in one year, was almost wholly from placers.

The distribution of tungsten ores is far from being as wide as the distribution of the granitic rocks, and some regions with large areas of granite have almost no tungsten minerals. Among such regions are the Scandinavian peninsula, large stretches of Canada, the eastern United States, and Brazil.

The world’s known large tungsten fields are grouped along the shores of the Pacific Ocean—not always close to it, but somewhere in the great mountain masses paralleling its margin, and the western shore is much richer than the eastern shore. In 1918, fully 92 per cent. of the world’s tungsten came from the shores of the Pacific, 61 per cent. coming from Asia, Australia, and Oceania, and 31 per cent. from North America and South America. Eastern Asia alone furnished 56 per cent. There is only one considerable tungsten-bearing area not situated close to the Pacific, that of the Iberian Peninsula, mostly in Portugal but partly in Spain. Of the less than 8 per cent. not produced around the Pacific, that area yielded nearly 5 per cent. There are, of course, small deposits in England, Germany and other places near the Atlantic, but together they produce less than 3 per cent. of the world’s tungsten ores. The huge continent of Africa has only negligible known deposits; none of consequence are found on the borders of the Arctic, Antarctic or Indian oceans except along the narrow Malay Peninsula dividing the Indian and Pacific oceans, and only minor deposits are known in Siberia.

Considered as a single metallogenic province, the region making by far the greatest production is in southeastern Asia; it includes the Malay Peninsula, Burma, the Shan States, Siam, Tonkin, and southeastern China. The second largest producing metallogenic province is the Cordilleran, including Bolivia and the adjacent closely related areas of Peru, Argentina and Chile, to which the United States and Mexico would be a close third.[77] Portugal, Spain and Italy form the fourth province, to which are closely related the Cornish-French producing areas. Australia, including Tasmania, is next in importance and is a distinct province, practically all the ores being found in the ranges of the eastern side of the continent. Japan and Korea also form a rather distinct province which may continue into Manchuria. Mexico, as has been indicated, should be included in the same province as the western United States. There are numerous small more or less isolated areas, like Connecticut, Nova Scotia, Manitoba, etc., that are at present of little importance and give no promise of future greatness.

The world’s production of tungsten ores by metallogenic provinces and political areas is shown in the following table:

Table 28.—The World’s Production of Tungsten Ore, 1913 to 1918, by Metallogenic Provinces and Political Areas[78]
In short tons (2,000 pounds) of concentrates containing 60 per cent. WO₃.

—The increase of output from eastern Asia has been marvelous. In 1913 it amounted to 2,497 tons and in 1918, as already stated, to 20,228 tons—more than 56 per cent. of the world’s production. As elsewhere, production must decrease until the accumulated stocks in the reducing centers are used, then production will again proceed. The alluvial deposits of China are by no means exhausted, the veins are scarcely touched, the tungsten-bearing area is large and only partly prospected, and such prospecting as has been done has been almost wholly for placers; labor is cheap, and a large future output is sure. More liberal ideas of trade and government are slowly taking root in China and ultimately educated Chinese or trained foreigners will work the deposits; the output for a long time will be large, though it may never again be as large as it was in 1918.

So far as can be learned, the easily worked placers and the upper parts of the veins in Burma are becoming exhausted rather rapidly,[84] and recourse must therefore be had more and more to the mining of those parts of the veins below water level and in harder rock, and this will probably mean a diminution rather than an increase in output. Siam seemingly should give an increased production, as the mines are comparatively new, and there still should be opportunity for discoveries. The Federated Malay States and the unfederated states (Johore, Kedah and Trengganu) should produce at least as much in the immediate future as in the past—given the demand and an equal price.

—Like other British possessions, Australia labored under the handicap of a comparatively low fixed price for tungsten ores during the war. This price, at first 55 shillings per long ton unit c.i.f. London, was later raised to 60 shillings. During the earlier part of the war the price paid in Australia averaged less than one-half the price paid in the United States, and only a little more than half that paid in regions other than the British provinces. In consequence the Australian tungsten production did not increase during the war as it might have done had prices been higher. The cream of the known deposits is gone except in Tasmania, where contact metamorphic deposits on King Island have quadrupled the Tasmanian output. The tungsten minerals mined in Australia are largely wolframite with smaller quantities of huebnerite and scheelite. The huebnerite seems to be rarely recognized as such in the British market, but is all sold as wolframite. Except for the contact metamorphic deposits on King Island, Tasmania, the deposits worked are mostly veins, with some pegmatites.

In New Zealand, the production is wholly scheelite; it increased considerably during the war until the last year—1918—when, apparently from a lack of efficient labor, it fell to the lowest point since 1909. The probabilities are that there will be a stoppage of output for the present.

—In Bolivia the increase of production has been great. The deposits seem to be wholly veins and derived placers. The veins are closely connected with the tin deposits, and in many veins tin and tungsten are associated, but many tungsten deposits contain little or no tin. The tungsten minerals mined are ferberite, wolframite, scheelite and some huebnerite. In some veins the minerals are mixed and in others wholly separate. The mines are in and on both sides of the eastern Cordillera of the Andes through a distance of nearly 400 miles from a point near Puerta Acosta, on the northwest, to Chorolque, on the southeast. Mining costs during the war rose greatly in sympathy with the rise in other parts of the world. Wages did not rise to great heights, but the cost of materials advanced decidedly. Transportation conditions are always bad in most of Bolivia, and heavily increase expenses. Because of circumstances the output is extremely sensitive to a decrease in demand or prices, and hence it fell quickly after the armistice, but should high prices come again, it will probably again increase quickly. Some modern plants were placed at mines before or just as the armistice was signed, and when world stocks of tungsten are used and when there is again a demand, some ore will be produced even at less than $10 a unit, though the average cost seems to be about $12 a unit, at the mine.[85]

The output of Peru, as now produced, seems to depend upon high prices and with such prices could probably remain at the level of 1916 for several years. The Huaura deposits are reported to be large, though of low grade, and may under proper management yield much ore even at lower prices. They were under the control of German firms during the war and probably still are.

—Until 1911 the United States was the leading tungsten-producing country, but in that year it was passed by Burma, which kept the lead until 1916, when the United States again became the principal miner of tungsten ore. In 1918 China entered the excessively high-priced market with an output that exceeded by nearly 1,000 tons the world’s production of any year before 1915. North America increased its output from 1,549 tons in 1913 to 6,512 tons in 1917, but dropped back nearly 1,000 tons (to 5,406 tons) in 1918. In the United States the decrease of production was due almost wholly to the fall in price, and only partly to exhaustion of deposits. In the Boulder, Colo., tungsten field some of its best ore bodies are worked out and the cost of production has risen greatly owing to the impoverishment of others, and the same thing is true in some other places, but it seems possible that in the country as a whole the production can be made about equal to what it has been before, provided prices are equally high, through the discovery of the contact-metamorphic deposits of the Great Basin.

In Mexico the tungsten deposits are seemingly a continuation of those of southern Arizona. So far as known, all the Mexican deposits carry scheelite, in places partly replaced by cuprotungstite. The known worked deposits in the Sahuaripa district of Sonora are described as veins containing scheelite with copper minerals and a pegmatite dike in which are large masses of scheelite and molybdenite.

—European production increased about 50 per cent. between 1913 and 1918, mostly in Portugal, and the output of tungsten ores in Portugal apparently did not reach its maximum. Both placers and veins have been exploited and there seems to be placer material still to be worked as well as veins that are said to be far from exhausted. The official statistics of production given by Portugal during the greater part of the war are declared by engineers conversant with the situation to have been too low, because of ore being smuggled into Spain and on board ships bound for England. On the other hand, in 1918 England and France objected to the shipment of Portuguese ore to the United States, but would not pay equivalent prices. The Portuguese government therefore issued an order preventing the export of tungsten ore except at fixed prices approaching the current American prices. American owners could not work their mines successfully under the British-French embargo, with the result that the output was probably much smaller than in 1917. In spite of the uncertainties the official estimates have been used as far as they are available, for no better figures are at hand.

As to the Spanish output, prophecy is difficult because the data concerning the mines are meager. It seems probable that under similar prices about the same output as in the past may be expected from the English and French deposits. The English output decreased in 1917 and increased only a little in 1918. No accurate data are available from France. The German and Austrian deposits were probably worked so hard during the World War that less is to be expected from them than they have heretofore produced.

—The principal changes in the distribution of production during the next few years would seem to be: Further development in Korea; possible development in Manchuria; development of deposits in southern China and Siam; further development in Bolivia; a tendency in the United States to largely increased production from deposits in the Great Basin; and development of both veins and contact-metamorphic deposits in Mexico. Production will possibly decrease in the Atolia and Boulder fields of the United States; and in Australia, Japan, Germany and Austria.

The actual control of the world’s tungsten deposits differs considerably from that indicated by the production within political areas. Actual control is justly obtained through ordinary competitive buying, ownership by nationals (sometimes by governments) of deposits, and through commercial alliance. Control through ownership of banks and transportation lines may be just or it may be by coercion and commercial brigandage, seizing ports for coaling and repair stations—methods that are merely refinements evolved since the days when “They sought their fortunes as they pleased abroad, the crown annoying them with no inquiry to embarrass their search for Spanish treasure ships, or their trade in pirated linens and silks.”[86]

Table 29.—Actual Control of the World’s Tungsten Output in 1917 and 1918.
In Short Tons of 2,000 Pounds

Owing to the close relationships between some foreign governments and private firms—as illustrated by the German government’s interest in dye, potash, and shipping firms, and the British government’s participation in nickel mining and ferrotungsten-making companies—it is not practicable to draw a line between governmentally and privately controlled deposits. In countries with weak governments, the deposits owned by British subjects are to all intents and purposes British; but foreign deposits owned by Americans are not necessarily under American control; in fact, instead of helping and encouraging our pioneers in foreign trade we are apt to harass them and destroy their business with drastic tariff laws.

In effect, the preceding table merely shows where the ores of different countries go for treatment; it is, of course, only a generalization, for trade conditions constantly change. For instance, Japanese electric furnaces are beginning to smelt tungsten ores, though at present to the extent of only 10 to 15 tons of contained tungsten per month, but it is conceivable that the output may be increased greatly. Although Japan could control the disposition of its ore, it is given credit for control only of its smelted ores. The exact distribution of ores from Argentina, Bolivia, Peru, Portugal and Spain can not be given.

—During the war the British government demanded and obtained all of the tungsten ores produced in its colonies and possessions. This restriction was later lifted as regards to Canada, and a new rule allowed Canada to ship tungsten ores to other Entente nations, but as Canada was not a producer the license granted amounted to nothing except as it eased the feelings of the Canadians. Scheelite deposits had been discovered in Manitoba, however, that for a time seemed to be potential producers. Nominally Siam has remained free from British control because more or less under the zone of influence of the French, but diplomatic pressure seems to have been exercised at Bangkok. The Siamese ores mostly contain some tin and have gone to Singapore for separation; and when once within the British possessions, of course they could not be exported. The English control of Siamese shipments, however, seems as complete as if the ores came from an English province. Mr. Nassuer, of the Siamese American Trading Co., testified before the Tariff Commission at San Francisco, June 28, 1918, that his company wished to ship ore to the United States but the British minister to Siam would give no permit. The company took the matter up with our State Department and finally got permission to ship 10 tons.

In February, 1918, the Chemical Products Co., of Washington, D. C., protested to the Department of State at Washington with reference to British interference with exportation of tungsten ore from Siam to the United States, stating that the company was working under conditions peculiar to itself in that it employed an expensive process developed to handle low-grade ores obtainable at a much lower price than the regular grades on the market; that it entered into an agreement with an American working tungsten mines in Siam for the purchase of his tungsten ore, only to find that through control of port privileges at Singapore and Hongkong the British effectually prohibited it or any other American firm from obtaining the material. Of course, this, like other incidents mentioned, took place under the shadow of a desperate war when strictness was to be expected, but the shipments asked were to an ally from a country not openly under control of Great Britain. Doubtless no such objections would be offered now, but the incidents show the efficiency of these methods of controlling commerce.

In southern China, Hongkong being the port for Kwangtung and Kwangsi, and parts of southern Kiangsi and Hunan, the British for a while exercised control over the export of ores produced in those districts,[87] refusing to allow the reshipment of ores unless they were sent to England.

Foreigners, including Americans of course, are not allowed to own mining property in Burma, the Federated and Unfederated Malay States, or Australia, territory producing nearly all the tungsten ores of the British Empire.

In Argentina small tungsten mines are owned by English companies.[88]

In Bolivia the English and French governments during the war leased mines directly, and came into direct competition with American business men engaged in buying or producing tungsten ores.

British traders are constantly striving to increase their control of Bolivian tungsten ores. At present the English seemingly have complete control of the financial system of Bolivia, so far as foreign exchange is concerned. An American interested in a tungsten mine in Bolivia has informed the writer that it is almost impossible to do business with English banks, because they insist that if they extend commercial courtesies, even for pay, the recipient must buy only English mining machinery. The buddle, which for dressing tungsten ore is obsolete in other countries, is said to be still used in Bolivian mills under English control. If miners do not wish to deal through English banks, they are compelled to cable money to and from New York at considerable expense. The American banking interests represented in Bolivia seem conservative in advancing money on ore shipments, whereas German and English representatives are said to advance up to 80 per cent. of the market value of ores shipped. Mining corporations controlled by English firms ship to England, and Americans can not compete for the production. Such a firm is Aramayo Francke Mines, Ltd., which produced 2,050 long tons of tin concentrates, 226 tons of wolframite concentrates, and a considerable output of bismuth in the year ending May 31, 1916. Control of the Bolivian mines by the English is not yet dangerous to American interests, except through the banking system, but entire control may be passed to them, to the Germans or the French, through American tariff legislation.

In Portugal, English companies control a number of the mines, and it has been alleged by at least two Americans[89] that the English government, through its representations at Lisbon, for a period of more than two years, prevented title passing to American companies. The Thermo Electric Ore Reduction Corporation, Ltd., seems to be the chief English owner of Portuguese tungsten mines.

In the Dutch East Indies, the British are understood to control the present wolframite production of about 5 tons a month.

—French control of tungsten deposits is not large. It includes the production of France and of Tonkin, a part of that from Portugal, and a comparatively small interest in Bolivia. During the war, control in Portugal was attempted by England and France. The prices offered by the English and French were much below the market prices at New York, and the Portuguese government stepped in and raised prices to a point somewhat lower than those of the United States, but 20 per cent. higher than the prices offered by England and France.

—Japan has within her own borders a considerable number of tungsten deposits in the southern part of the islands, but all are small. In Korea important deposits have been discovered and actively worked, especially within the last two years. Deposits in Manchuria are said to be controlled by the Japanese; little is known of them, and if they exist they are probably small. Japanese ores have largely come to the United States for several years. As has been said, Japanese firms have erected electric furnaces in which a part of the tungsten ores are reduced, probably the equivalent of 25 to 35 tons per month of concentrates carrying 60 per cent. WO₃.

—The United States controls entirely the tungsten deposits within its own borders and Alaska. Americans operating in Mexico have produced 200 to 300 short tons of scheelite concentrates per year, from deposits in the Sahuaripa district, Sonora. Wolframite is said to have been shipped from Sinaloa to the United States, but its real origin is unknown. Contact metamorphic deposits about 60 miles southwest of Nacozari carry 0.7 per cent. WO₃ and 1 to 2 per cent. copper. They are owned by Americans but are not now productive.

In Bolivia, Americans own some of the more important tungsten mines. The American firms known to own tungsten properties there are W. R. Grace & Co., local address, La Paz; Stewart, Wilson & Hepburn, Oruro; Easley Inslee, La Paz; and C. Dillon, Oruro. Their total output is estimated to amount to about 1,600 tons, out of a total output of more than 4,000 tons for the country.

In southern China, American firms have largely developed the tungsten trade, so that through this source the United States (or rather American capital) controls, unless hindered, a yearly output of perhaps 9,000 short tons of tungsten concentrates.

In Siam one or two United States companies have attempted to produce tungsten, but English influence during the war made difficult the shipment of even small lots of ores to this country.

Because it offered higher prices than other countries, and because the more direct and shorter trade route made trade with this country advantageous to the Japanese, the United States largely controlled the Japanese output of tungsten ore in 1918. This trade probably has been somewhat curtailed and will be further diminished through the erection of electric furnaces in Japan. The table following shows the tungsten ores imported for consumption into the United States in 1918, but gives a poor idea of the ores shipped from the countries of origin; Chinese ores lag three months and South American ores about two months. The table gives only the ores actually received during the year. Table 29 shows more nearly the ores shipped to the United States during the year.

Chinese ores are treated as averaging 67.5 per cent. WO₃ and other ores 65 per cent. WO₃.

Table 30.—Tungsten-bearing Ores Imported into the United States in 1918, by Countries as Listed at Ports of Entry, and by Probable Countries of Origin

Unhindered by other governments, this country would have imported even larger quantities of ore, because of its paying higher prices and being more liberal regarding impurities.

The table shows that the United States imported 36 per cent. of the tungsten output of the world; this amount added to the domestic output makes a total of 17,921 tons, or 50 per cent. of the world’s production. Owing to the lag in shipments from South America and China the South American ores received in January and February were from the output of 1917, as were the Chinese ores arriving up to the end of March. Subtracting the ores arriving from the two regions during the first two and three months, respectively, of 1918, and adding the ores arriving during a like period in 1919, make the quantity of ore controlled by the United States in 1918 (as shown on page 153) equivalent to 21,131 tons of concentrates carrying 60 percent. WO₃, or 59 per cent. of the world’s production. These ores were all controlled through the private initiative of American firms who offered better prices and better terms than could be obtained abroad. Probably a larger proportion could be handled in the future, should interference not come from within our own borders. It is now proposed to put a tariff of $10 a unit on tungsten ores without regard to purity or quality, with a correspondingly high tariff of $1 a pound, plus the 15 per cent. ad valorem duties now in force, on metal in any form—element, alloy or salt; and such a bill has passed the House of Representatives. Its advocates believe that the price, now about $7 a unit in New York, will be raised to $17 a unit.

Hereafter the quantities of tungsten ore handled will be much smaller than during 1916, 1917 and 1918; and will be confined to peace-time needs unless some unforeseen war arises. England, according to government estimates about January, 1920, had two years’ supply, and France is probably as well supplied. The United States probably had on hand an equivalent of quite 8,000 tons of ore carrying 60 per cent. WO₃. Makers of tool steel figured on a consumption of 7,500 tons during 1919, but because of the lack of market for ore this was much too high; and probably 4,000 tons is large enough, so that there will likely be little market for new supplies for nearly two years, except as ore may be bought speculatively. During this time, mines everywhere must remain idle until a demand again arises, except for those mines required to furnish tungsten for Germany, Austria and Russia and the small quantity required by Sweden, Norway and Italy. If industries in Germany, Austria and Russia recover so that they can buy and use tungsten, Germany will have regained in the ores that will be eagerly offered by producing nations needing a market, a part of the trade she has lost. Traders of England, France and the United States will be glad to sell tungsten and ferrotungsten, but Germany will undoubtedly reach out for raw material in order that she may make as much use as possible of her abundant unemployed labor. Should a tariff law like that now proposed be passed, the United States will have cut off its foreign supplies and will have ended its control of any considerable part of them. However, should a high price be maintained, artificially or otherwise, the development of other alloy steels for use in multiple-edged tools may have reached a point where not so much tungsten will be needed.

—Germany had no considerable tungsten deposits at home, and none in the foreign territory she held, but in 1913 her control through business alliances covered about two-thirds of the world’s output of tungsten ore. In that year, according to the German official figures, 5,295 short tons of tungsten ores were imported. Most of this probably carried 65 per cent. or more WO₃, equivalent to, say, 5,736 tons of concentrates carrying 60 per cent. WO₃. Adding the 106 tons of Saxon concentrates produced in that year shows that Germany treated a total of approximately 5,840 tons out of a world’s output of 8,864 tons, or about 66 per cent. of the total. The United States in the same year produced 1,537 tons and imported 449 tons of unknown content, but the whole was probably equivalent to more than 2,000 tons of ore carrying 60 per cent. WO₃, leaving only about 1,000 tons for other countries, most of which seems to have been treated in France. This trade Germany lost when with Austria she started the World War. With the cutting off of all shipments by ocean to Germany, most of the foreign ores were denied her, but undoubtedly small quantities leaked in through Sweden and Norway for some time after the war began. The small output of Austria was always available, and it is said that a considerable quantity of ore was smuggled across the border of Portugal into Spain, thence by water to the western frontier of Italy, into Switzerland, and from there shipped direct to Germany. A considerable part of the Spanish production is said to have reached Germany in this way also, and the “crippled” submarines that ran into Spanish ports are reported to have carried out cargoes of tungsten for Germany. From available data it is impossible to confirm or to disprove these reports, and, in giving them, their doubtfulness is fully recognized, but such possibilities must be acknowledged.

In the Allied countries and the United States, the German interests were taken over by the governments, but in South America the German firms still hold some control of tungsten-bearing properties. In Bolivia four German firms are said to have an output of about 600 metric tons of ore a year. In Peru what is said to be the larger part of the tungsten deposits has been controlled by firms thought to be German, E. y W. Hardt and Carlos W. Weiss y Cia. In Argentina the Hansa Mining Co., a German concern, is the principal producer. Its output is said to be about 500 tons of concentrates a year, but even this output is said to have come to the United States during the war. If the United States is placed under a prohibitive tariff, Germany may easily recover a large part of her control of the world’s tungsten trade.

The spread of knowledge, particularly that regarding electric furnaces, makes the control of the tungsten trade through secret processes or superior skill extremely difficult, and so far as the United States, Great Britain and France are concerned, gives little advantage to any one. Japan is perhaps somewhat less advantageously placed. Smelting plants are so easily, quickly and cheaply erected that they do not offer any great chance for monopoly. Cheap power, high technical skill and knowledge, originality and boldness in experiment, excellence of organization, generous dealing with producers, an honest product honestly sold, good transportation facilities, and broad sane laws are the elements that will give control. The United States may have this control through reasonable effort, but selfish laws may still more easily wreck control of the larger part of the world’s trade, reduce our tungsten business to a provincial scope, and make the product high priced for all time.

In years of good business before the World War, the United States used an equivalent of 3,000 to 4,000 short tons of concentrates, carrying 60 per cent. WO₃ per annum. When the war began there was a lull while the attacked countries caught their breath and prepared for a long struggle. After plans had been made, and the manufacture of munitions had begun on a grand scale, the demand for tungsten rose enormously. All kinds of ores were taken at fabulous prices. Ores carrying tin, phosphorus, sulphur and bismuth, that before would not have been considered by steel makers, were taken with avidity, and there was a great scramble for deposits. In October, 1918, the United States was using tungsten ores at the rate of 20,000 tons per annum. Meanwhile prospecting had uncovered so many new deposits and they were so actively exploited that great stocks of ores were accumulated in the Entente countries. On the other hand, in this country many of the known deposits showed signs of impoverishment, a number after being worked profitably for a short time became wholly inoperative, and it is likely that some of the deposits that have seemed to be the richest will never again produce largely. Among the new discoveries were the contact metamorphic deposits of the Great Basin, in California, Nevada and northeastern Utah. They were partly developed, and several promise well, but the irregularity of contact metamorphic ore deposits is notorious.

In 1916 with prices ranging from $15 to $93.50 per unit, the United States produced 5,969 tons of concentrates; in 1917 while still under the impetus of the 1916 boom, with prices ranging around $25 per unit, 6,144 tons; and in 1918, with prices still averaging about $25 per unit, 5,041 tons, although little was produced in December. Under a price of $17 per unit, which tariff advocates think can be reached by means of a tariff of $10 per unit, it seems improbable that the United States can depend on a production of more than 3,000 tons per annum for the next three years. There are, of course, possibilities of a larger production and there are equal possibilities of a smaller. Should another great war take place, an event that is not beyond the range of imagination, the United States would probably begin by using tungsten at the rate of 20,000 tons of concentrates per annum. Unless the price were even more extravagant than the highest price in 1916, $93.50 per unit, the United States could not produce half of its needed concentrates, and the time required to reach even that output would be far too long for safety. Of course, such a production would be much better than none, but the United States should, for safety, have within reach at least a year’s supply.

The Pacific, around the borders of which are the largest tungsten deposits, is by many looked upon as the next large theatre of war, and however vitally they were needed, the obtaining of supplies of tungsten ores might become impossible though the blocking of trade routes. It would, therefore, seem vastly better that, instead of putting a premium on the quick depletion of our own supplies, which are already too meager, we should use the rich low-priced ores now being mined in the Orient. These cheap ores we may have in trade for the asking, and it would be one of the best forms of national life insurance for the government to store 10,000 tons of these ores while they may be had.

The argument is often made that by putting a high tariff on tungsten ores we would have our own deposits so developed that quick production could be made when needed; also that with the need we would find more ores. Both arguments are specious. What is meant is not development but removal. No one will open a tungsten mine to let the ores stand against the country’s day of need. The finding of new ores is a probability, but the quantity is wholly a question. Few tungsten mines of the United States can be profitably worked at the present price of about $7 per unit, and the mines are now closed. The number of persons dependent on the mining of American tungsten ores is small, probably less than 900 in peace times. At present most tungsten miners have already obtained other employment, and practically all could obtain employment fully as profitably in other mines, many of which are short handed, so that no great hardship would be worked. As a matter of national economy, the United States can not afford to throw away its chance to buy cheap tungsten ores while they are available. Aside from the question of insurance and even of existence during another war, not to buy South American ores is to throw away South American trade. In a degree this is also true of Chinese and Japanese ores.

The metallurgy of tungsten, like that of other metals, is being improved constantly, and should our ores remain in the ground for a time they will be of greater absolute value when mined, for there will be less waste in conversion. If our ores are mined now under an artificially high price, we will always pay a high price for tungsten ores, for when ours are used the ores in other countries will have diminished in quantity and increased in cost; prices would be higher and we would have to buy at the advanced rate. On the other hand, by holding our markets open to cheap ores from any quarter, we will stand on an equal footing with other countries and will always have a reserve of high-priced ores available in an emergency.

There is but one crop of ore. Deliberately to turn over all the cheap tungsten ores of the world to our competitors, allowing them this advantage in making high-speed steels with which to compete in foreign trade with our steels and with all products on and in which they are used; to put a premium on the early depletion of our own deposits of this indispensable metal; and to compel our use always of high-priced ores—these would be economic crimes.

CHAPTER VIII VANADIUM By R. B. Moore — USES OF VANADIUM — Substitutes. — CHANGES IN PRACTICE — GEOLOGICAL AND GEOGRAPHICAL DISTRIBUTION — Peruvian Deposits. — Other Foreign Deposits. — Deposits in the United States. — POSITION OF LEADING COMMERCIAL NATIONS — DEVELOPMENTS AND CHANGES IN KNOWN GEOGRAPHICAL DISTRIBUTION IN THE NEAR FUTURE — POLITICAL AND COMMERCIAL CONTROL

The main use of vanadium is in steel. It is used where great toughness and torsional strength are required, as in automobile parts, gears, piston rods, tubes, boiler plates, transmission shafts, bolts, gun barrels, gun shields and forgings of any kind which have to withstand heavy wear and tear. The vanadium content of such steels varies from 0.1 to 0.4 per cent. Vanadium is occasionally used in certain tungsten alloys for making high-speed tool steel, the introduction of a small proportion of vanadium decidedly reducing the proportion of tungsten required to give such alloys the desired hardness and toughness.

Arnold has given some illustrations of the effect of vanadium on steels of different types:

Vanadium, therefore, differs from tungsten in having an extremely beneficial effect, not only on tool but also on structural steel. Arnold has shown that vanadium seemingly does not form a double carbide with iron, but gradually takes the carbon from the carbide of iron until, if about 5 per cent. of vanadium is present, Fe₃C can not exist, and only a vanadium carbide, V₄C₃, containing 15 per cent. of carbon, is present; and this constituent is constant, at least in tool steels containing 5 to 14 per cent. of vanadium. The micrographic analysis of such alloys has resulted in the discovery of three new constituents, namely, vanadium pearlite, vanadium hardenite, and vanadium cementite.

Chromium-vanadium steels are the latest development in structural alloy steels that have gained an extensive market. Almost all these steels are made in the open-hearth furnace; the chromium and vanadium alloys being added shortly before casting. In their physical properties these steels are much like chrome-nickel steels, but they have a greater contraction of area for a given elastic limit than the latter. The greater part of the chrome-vanadium steels made goes into automobiles. Some manufacturers prefer such steels because of their greater freedom from surface imperfections, notably seams, which steels containing nickel are prone to have if the ingots are at all unsound. These steels are almost always used in the heat-treated condition, but even in automobiles some frames, forgings and shafts are made of the steel in its natural state.

Some chrome-vanadium steel is said to be used in armor plate of medium thickness, which is not face-hardened but has high resistance imparted by heat treatment.

Vanadium is also used to some extent in making bronzes, in medicine and in dyeing.

—Several substitutes, chiefly titanium and molybdenum, have been claimed to give the properties of vanadium in steel. Both of those metals give to steel some of the properties that are usually associated with vanadium, but neither one takes the place of vanadium entirely.

The Primos Chemical Co. (see later) has its own patented method for treating roscoelite, the ore found at Newmire, Colorado. This method consists in roasting the ore with salt containing a little pyrite, and is a method that is applicable to some extent to most vanadium ores that do not carry lead. The American Vanadium Co. has a secret process for the treatment of its Peruvian ores. This method has not been published. The treatment of vanadinite, cuprodescloizite and carnotite ores has been studied by the U. S. Bureau of Mines, at Golden, Colorado. Whatever change in practice takes place is likely to be mainly in the concentration of vanadinite and in the treatment of this mineral and cuprodescloizite.

—The largest deposits of vanadium in the world, and the most important, were until recently controlled by the American Vanadium Co. of Pittsburgh, Pennsylvania, which in 1919 was absorbed by the Vanadium Products Corporation, allied to the Bethlehem Steel Corporation. These deposits are at Minasragra, Peru, 20 miles from Cerro de Pasco. The area lies along the western limit of a broad anticline in Juratrias and Cretaceous rocks. A section shows the series in this locality to be composed of green shales, thin beds of limestone, and red shales. Vanadium is found only in the red shales. The deposit proper appears to be a lens-shaped mass, 28 feet wide and 350 feet long. The ore contains several minerals. The mineral that constitutes the large portion of the deposit is called “quisqueite”; it is a black carbonaceous substance containing sulphur. There is also a lesser quantity of a coke-like material. Neither of these contains vanadium. The vanadium is mostly at the southern end of the ore body, and to a depth of 20 feet is largely in the form of red calcium vanadate, which is brighter colored then the calcium vanadate in Colorado and Utah, and carries as much as 50 per cent. vanadium oxide. It occurs in small pockets and fills the cracks and fissures in a fine shale. Below this shale is the “mother lode,” which is 9 to 30 feet thick, extends along the greater length of the deposit, and carries as high as 10 per cent. vanadium oxide and nearly as much sulphur. On the east and south sides, below the “mother lode,” is a hard blue-black vanadium shale, carrying as much as 13 per cent. vanadium oxide and 4 to 5 per cent. sulphur. Patronite, the main vanadium mineral, is greenish black and contains 19 to 24.8 per cent. vanadium oxide and in places 50 to 55 per cent. of combined sulphur. The patronite originally almost reached the surface and is most abundant in the north half of the lens. The whole ore body is almost completely inclosed by porphyry dikes and contains two or three intrusions. These deposits are controlled by the American Vanadium Co., and its successor, the Vanadium Products Corporation, through a concession from the Peruvian government. They are large, but are by no means inexhaustible, and as they are entirely local they are not likely to be duplicated. No similar deposits are known, either in Peru or in any other part of the world.

In 1917 the American Vanadium Co. treated 5,236 gross tons of ore, from which it extracted 2,122,005 pounds of vanadic acid. From this vanadic acid the company manufactured 4,925,014 pounds of ferrovanadium. The company did not buy any ore in this country, but relied entirely upon its Peruvian production.

—The deposits in Peru are the only deposits of any commercial importance outside of the United States. Vanadium is found in South Australia, associated with carnotite and other uranium minerals. Small quantities of vanadic oxide are obtained as a by-product in the treatment of these ores.

Vanadium is also associated with uranium minerals in the Andijan district, Central Asiatic Russia. The vanadium is usually found as turanite, or copper vanadate; ferganite, an ortho-vanadate of uranium; and as several other new minerals. The amount of ore seems to be reasonably large, and this district may ultimately become a source of both uranium and vanadium.

The lead ores of Mexico contain some vanadium, the best known deposits being in the northeastern part of the State of Chihuahua. Other deposits are reported in Zacatecas, Guanajuato, San Luis Potosi, and Hidalgo.

—The principal vanadium deposits of the United States occur in a metallographic province covering southern and southwestern Colorado, southeastern Utah, and parts of Arizona and New Mexico. Uranium and radium characterize the same province.

Probably the largest deposits of vanadium yet discovered in the United States are in southwestern Colorado in San Miguel County. These deposits were visited by Ransome and Spencer in 1899 and their description, together with notes on the chemical analyses and composition of roscoelite by Hillebrand, was published in 1900. Fleck and French have also described the deposits. Fleck and Haldane later published additional descriptions, with notes on mining operations. Hess, in 1912, published an excellent description of these deposits with notes on the possible origin, etc.

According to Cross and Purington, the country rock is composed of Jurassic and Triassic sediments, divisible into three formations, the Dolores below, La Plata above and McElmo above La Plata. The latter is composed of two heavy beds of light-colored sandstone, separated by a thin bed of limestone. The vanadium-bearing rock is the lower sandstone. It is a light to dull green, and fine-grained. Occasionally splotches of carnotite are found in the cracks and fissures, but the uranium content is too small to be worth saving.

According to Hillebrand, the green vanadium mineral to which the sandstone owes its color is not a chlorite, but is closely related to the mica, roscoelite. The ore mined has an average content of 1¹⁄₂ per cent. V₂O₅. These low-grade roscoelite deposits can be mined at a profit, because they are large and easily worked.

Undoubtedly these deposits have been feeling the effects of the rather large production of the last few years, and the average grade of the ore is now probably at least half of a per cent. lower in V₂O₅ than it was a few years ago. There is still considerable ore untouched that will average 1 per cent., or a little less. The British government for several years, according to reports, has been interested in obtaining control of vanadium deposits.

The Primos Chemical Co., with works at Newmire, Colorado, and Primos, Pennsylvania, is mining these deposits, and in 1917 made this production:

Treated 60,907,000 pounds of ore; from this was produced 496,731 pounds of vanadium in the form of iron vanadate running about 34 per cent. metallic vanadium. From this was produced 417,770 pounds of contained vanadium in the form of regular 40 per cent. ferrovanadium. In 1918, up to and including July, this company mined 17,449,000 pounds of ore, from which was produced 149,343 pounds of contained vanadium in the form of vanadate of iron and 133,666 pounds of contained vanadium made in the form of 40 per cent. ferrovanadium.

In 1919 the Primos Chemical Co., was absorbed by the newly organized Vanadium Products Corporation.

Vanadium ore has been discovered in Huerfano County, Colorado, near the Sangre de Cristo Range. The vein is said to be well defined and 1 to 4 feet in width. A number of assays show 2 to 7 per cent. V₂O₅ content, and others 2 to 4 per cent. copper. The ore is heavy, black and banded; it contains small quantities of uranium oxide, but should be classed as a vanadium, rather than a uranium mineral. There has been no commercial production up to date.

In Eagle County, 7 miles southeast of the town of Eagle, a silver ore has been found that carries vanadium. This was located mostly in the Lady Bell mine. The ore, a dark-greenish sandstone similar in appearance to the darker types of roscoelite ore found in San Miguel County, assayed from 25 to 1,000 ounces of silver to the ton. The mine has been largely worked out for silver, the vanadium being lost during the smelting process. There is still, however, an appreciable amount of vanadium ore left, as the low-grade silver ore was not mined or treated.

A considerable amount of vanadium is obtained as a by-product from the treatment of carnotite (uranium and radium) ore. It is difficult to say just what the yield from this ore is, but it is probable that it averages about 200,000 pounds of vanadic oxide per annum. This is produced by five or six operating radium companies. These deposits are found in southwestern Colorado, around the Paradox Valley, and in southeastern Utah, extending as far as the San Rafael Swell, southwest of Green River, Utah.

There is considerable ore running one-half to 1 per cent. uranium oxide which carries from 4 to 10 per cent. vanadic oxide. In the past this ore has not been mined, because the extraction of radium from it would not pay. With a strong demand and a high price for vanadium, at least the higher grades of this ore could be mined at a profit. There is considerable of such ore at certain localities north of the Paradox Valley; unfortunately, these deposits are somewhat scattered and some would involve not only long wagon hauls, but also transportation by burro to wagon roads. Only the higher-grade ore could be handled in this way at a profit, and the difficulty is to get enough to justify building a treatment plant.

The writer has been told that there are deposits of this same type of ore at Temple Mountain, 40 miles south of Green River, Utah.

A small vanadinite deposit, containing traces of wulfenite, has been found near Klinefelter Station, on the main line of the Santa Fe Railroad, near the eastern border of San Bernardino County, California. The ore is largely calcite and is low grade, averaging probably from 1 to 2 per cent. vanadic oxide.

A deposit of vanadinite in Sierra County, New Mexico, on the Atchison, Topeka & Santa Fe Railroad, was mined for a short period in 1912 and 1913. Besides vanadium, the veins contain galenite, copper carbonates, barite, fluorite and other minerals. The ore was treated at a mill close to the mine, but the whole undertaking was unsuccessful, probably because the ore was so low grade, and because of metallurgical difficulties. There are a number of other deposits of vanadinite in New Mexico, but none of them have been commercially developed in any way.

Vanadinite is found in a considerable number of places in Arizona, frequently associated with wulfenite, or lead molybdate. Indeed, one of the difficulties of producing both vanadium and molybdenum from vanadinite and wulfenite is the fact that the two minerals are frequently so closely associated that, because of the slight difference in specific gravity, it is not easy to separate them by mechanical methods. At the Mammoth mine, in Arizona, the upper levels are richer in vanadinite than in wulfenite, but at the lower levels, the reverse is true. Undoubtedly a considerable amount of vanadinite could be produced from this mine and others in the vicinity, but it is doubtful whether it could be done at a profit, even at a high price for vanadium.

The United States Vanadium Co. has a mine 4 miles from Ray Junction, Arizona, and at the mine a small mill to concentrate the ore, which is low grade, and produces vanadium from the concentrates. The amount of ore that can be obtained from this mine is somewhat doubtful. This is the trouble with vanadinite as a whole; it exists over a wide territory, but the deposits are all low grade and apparently are not extensive in any one locality.

One of the most promising deposits, as regards increased production of vanadium, is at the Shattuck mine, Bisbee, Arizona, where a large vug, or cavity, is lined with a vanadium mineral, probably cuprodescloizite. The ore carries about 8 to 10 per cent. vanadic oxide, in addition to copper and lead. This seems to be one of the best opportunities for an increased production of vanadium in this country. The Golden, Colo., station of the United States Bureau of Mines made a metallurgical study of the treatment of this ore.

Plate V.—Geographical distribution of the vanadium deposits of the world.

The distribution of the vanadium deposits of the world is shown in Plate V.

The United States is peculiarly fortunate as regards vanadium products, for it is practically the only producer of vanadium in the world, the Peruvian deposits being under the control of an American company. Therefore, England, France, Germany, Japan and other nations are forced to buy of American companies.

The larger part of the vanadium that has been used in this country has come from the mines of the American Vanadium Co. in Peru, but the Primos Chemical Co. produced an amount of vanadium from its claims at Newmire, San Miguel County, Colorado, that at least tended to give some real competition to the American Vanadium Co. As already stated, these claims are not nearly as rich or productive as they were, but they are probably good for several years more. The ore from Peru can be counted on probably for several years at something like the present output. The same statement applies to carnotite ore, and it is likely that the production of vanadium from carnotite may increase to some extent, as the demand for radium is strong, and there may be a consequent increase in the treatment of lower-grade carnotite. As this low-grade material usually carries more vanadium, the production of vanadium from this source may increase.

Vanadinite may prove to be a source of vanadium, although it is doubtful whether any large quantity can be produced from this mineral. As already stated, cuprodescloizite is probably the best source for an immediate increase in production.

As regards foreign countries other than Peru, Russia is the only one likely to produce any appreciable amount of vanadium ores, and undoubtedly no such production will be obtained until industrial conditions are more settled.

The American Vanadium Co. holds its mines in Peru through a concession from the Peruvian government. Thus at least two-thirds of the vanadium production of the world is practically in the hands of the Peruvian government, although the company operating is American.

Formerly the American Vanadium Co. was the only producer of vanadium products and ferrovanadium in the world. The price of vanadium was then somewhere around $5.00 per pound for the metallic vanadium content of the ferrovanadium. Later the Primos Chemical Co. came into the field, and the American Vanadium Co. cut the price. On account of the large deposits of ore that the Primos Chemical Co. had in Colorado, the result was simply a lowering of the price of ferrovanadium. Undoubtedly, if it were not for this competition the price of vanadium during that period would have been higher than it was, and if it were not for the Primos Chemical Co., the American Vanadium Co. would have had practically a monopoly of the whole vanadium production, as the output from carnotite was not large enough to affect the market seriously. As it was, these two companies controlled more than 90 per cent. of the ore supply, and thus the recent change of ownership to the Vanadium Products Corporation will enable the latter to fix the price, as well as to regulate the consumption and thus prolong the availability of a useful metal which otherwise would be likely to soon become exhausted. The principal vanadium deposits of Chihuahua, Mexico, are controlled by the Madero estate (Mexican).

This dominance of control of sources of supply has made control through ownership of reduction plants, patents and secret processes of less importance.

CHAPTER IX ANTIMONY By H. G. Ferguson and D. A. Hall — USES OF ANTIMONY — GEOLOGICAL DISTRIBUTION — GEOGRAPHICAL DISTRIBUTION, AND POLITICAL AND COMMERCIAL CONTROL — North America. — South America. — Europe. — Asia. — Africa. — Australia. — POSITION OF THE LEADING COMMERCIAL NATIONS — The United States. — England. — France. — Germany. — Japan. — RECENT CONDITIONS IN THE INDUSTRY — SUMMARY

The following summary of the uses of antimony is taken from Mineral Resources of United States, 1918.[90]

During the war Germany used antimony to some extent as a substitute for more important metals in the manufacture of currency, but shortage of antimony itself did not allow this use to become important.

The geological distribution of commercial antimony depends, with a few exceptions, upon the distribution of the principal ore mineral, stibnite (antimony sulphide). Cervantite, sernarmontite and valentinite are antimony oxides resulting directly from the decomposition of stibnite near the surface, and with other oxidized products form the chief ores of certain districts. Metallic antimony, also a result of oxidation of the sulphides, is rarely found, and still more rarely is it an ore mineral. Jamesonite, the sulphide of antimony and lead, is of frequent occurrence and is the principal ore of one important deposit in Mexico. Antimony is also recovered from the refining of antimonial lead.

Stibnite occurs in quartz veins and related deposits. Many of the important antimony deposits of the world occur in more or less close genetic relationship with eruptives of Tertiary age. The ore often gives way to pyrite with depth. A few important deposits occur in connection with intrusive rocks formed at considerable depth and are probably of contact metamorphic origin.

Although there is a wide diversity in the forms of the deposits and the nature of enclosing rocks, stibnite shows a distinct tendency to form replacements in limestone. The chief gangue minerals are quartz and calcite. Of other sulphides pyrite is the commonest, but cinnabar, realgar, chalcopyrite, galena, and sphalerite are often present as accessories. A characteristic feature of stibnite deposits is the relative scarcity of other sulphides; and it is equally true that important sulphide deposits of other metals rarely contain stibnite. An exception to the general rule is cinnabar, the sulphide of mercury, which is a characteristic mineral of certain stibnite veins. Likewise stibnite is one of the minerals most frequently associated with cinnabar deposits.

Several of the most important antimony districts owe their production of that metal to the presence of recoverable amounts of gold. This is true of certain French, Hungarian, Australian, and South African deposits.

Although antimony has been produced at times from a great many localities in the world, in only a few countries have deposits been developed to an important extent commercially. Under normal conditions of consumption the potential supply of antimony ore is far in excess of the demand. Consequently only those deposits that can be cheaply worked and are favorably situated with regard to markets, or contain appreciable amounts of other minerals, principally gold, have been extensively exploited.

The antimony-producing countries of the world may be divided into three groups as follows:

1. Chief producing countries in order of importance: China, France and Algeria, and Mexico.

2. Countries in which production is irregular in normal times but in which potential reserves are considerable, and production becomes important at high-price levels: The former Austrian Empire, Bolivia, Australia (Victoria), Burma, South Africa, Italy, Spain, and Asia Minor.

3. Countries in which normal production is small and in which known reserves are probably less important: United States and Alaska, Canada, Peru, Germany, Turkey (Asia Minor), Serbia, Portugal, Borneo, Indo-China, and Japan.

Plate VI shows the geographical distribution of the chief antimony deposits of the world.

The production statistics of the various countries are so little in accord that it is impossible to give more than a rough comparison between the important producers. As nearly as can be estimated the output of antimony ore in 1913, the last year for which even approximately complete statistics are available, amounted to about 20,000 metric tons of recoverable antimony. The consumption is even more difficult to estimate, as customs figures for different countries vary widely. The following table shows the relative importance of the principal producing and consuming countries in terms of percentage of the world’s output in 1913:

In the following discussion of the world’s antimony resources, political control is largely indicated by the country headings, under which are summarized the essential features of the commercial control of production, by ownership of mines and reduction plants, and by trading interests.

United States.

—Antimony deposits occur in many places in the United States, but during peace times the comparatively high costs of mining in this country do not permit competition with the Chinese and Mexican mines. A small production of antimonial lead from domestic ores was made prior to the war and a small amount of antimony recovered as a by-product of lead refining, but except for this the country was entirely dependent upon imported antimony.

High prices following the outbreak of the war brought a quick response in the production of antimony ores. The mine production of antimony ore in 1915 was about 5,000 short tons containing 2,100 short tons of metal, and in 1916 was 4,500 short tons containing about 1,770 short tons of metal. The lower prices of 1917 were reflected in the decreased output for that year, amounting to 1,060 short tons of ore containing 390 tons of metal. The 1918 production was 190 tons, containing about 50 tons of metal.

The chief producing states in order of importance were Nevada, California, Alaska, Washington, Oregon, Idaho, and Arkansas. Utah and Arizona yielded insignificant amounts. In Nevada the Sutherland mine, in Humboldt County, was the principal producer. In California, the greater part of the output was from two mines in Inyo and Kern counties operated by the Western Metals Co., of Los Angeles, the ore being shipped to San Pedro, near Los Angeles, for smelting. In Washington the antimony was produced at the property of the Gold Creek Antimony Mining & Smelting Co., in Okanogan County. In Oregon the Jim Dandy mine, near Baker City, was the principal producer. In Arkansas one property in Sevier County yielded a noteworthy output of ore in 1916 and also a small quantity of metallic antimony at a local reduction plant. In Alaska the production was mainly from the Fairbanks district, the ore being shipped to Los Angeles and Seattle for smelting.

The ownership of mines within the United States does not play an important part in the present control of the world’s resources, inasmuch as production under normal conditions is insignificant. It is possible that with the development of new uses for antimony, and a greater demand for that metal, the reserves in this country may become of commercial importance.

About 40 per cent. of the Mexican antimony output is controlled in the United States. An American-owned smelter was built during the war at San Luis Potosi. Ores from mines in this region have also been shipped to the Western Metals Co. at Los Angeles. An American concern, the Antimony Corporation, owns a large deposit of jamesonite, antimony-lead sulphide, in Mexico, which constitutes an important reserve that has not yet been developed. Antimony deposits in northern Mexico were worked by American capital during the war. Prior to the year 1914 only one company in the United States had attempted the smelting of antimony. During the war considerable activity prevailed, however, and several companies undertook the smelting of foreign and domestic ores. China, Bolivia, and Mexico were the principal sources of supply. The success of all these enterprises has been only temporary, as under normal conditions the high cost of production in this country prevents successful competition with Chinese and Japanese metal. American smelting interests exert little control on the antimony of the world at present, and can not be expected to do so in the immediate future. The smelter capacity of the country is estimated at 6,000 to 7,000 tons of metal per annum, all of which is now idle. One company, the Antimony & Compounds Co. of America, is closely connected with a French company, La Lucette.

Canada.

—Antimony production in Canada has been extremely irregular. During periods of high prices a considerable output was obtained, the years of maximum production being 1898, with shipments of 1,344 short tons of ore, and 1907, with 2,016 short tons. Mining ceased in 1910 and was not resumed until 1915. In 1915, 1,341 tons of 40 per cent. (metal content) ore were produced; in 1916, 885 tons of 42 per cent. ore; and 361 tons in 1917.

The principal producing district is at West Gore, Nova Scotia, where the ore in addition to its antimony content has a tenor of 2 to 4 ounces of gold per ton. Other regions that have produced antimony ore are New Brunswick (York County), British Columbia, Quebec, and Yukon Territory. In British Columbia (Slocan District) and Yukon Territory (Chieftain Hills) antimonial lead ores are also worked. The Nova Scotia ores, which furnished the bulk of the production, have been exported to England since 1915; the earlier production went to Germany. The small production of refined antimony came chiefly as a by-product of lead refining at the smelter of the Consolidated Mining & Smelting Co., at Trail, B. C.; a small amount of antimony was also smelted from antimony ores by the New Brunswick Metals, Ltd. (formerly the Canadian Antimony Co.) at Lake George, N. B. Canada appears to be in about the same position as the United States with reference to antimony mining. High prices, continued over a long period, will bring out a considerable production, but no output is to be expected at peace-time prices.

Mexico.

—Antimony deposits exist in many parts of Mexico and there has been a considerable production for many years. As in other countries, the output increased largely during 1915 and 1916. The production of metallic antimony for 1917 is reported as 2,141 metric tons. In 1914 there were exported to England 1,543 long tons of crude antimony and regulus; there were no exports to England in 1918, but 1,449 short tons of ore and 2,660 of metal were shipped to the United States.

The principal mines are in the Sierra Catorce, in the states of San Luis Potosi and Queretaro. The ores are mixed sulphides and oxides and carry 5 to 50 per cent. antimony.

A smelter with an annual capacity of 6,000 tons of metal was built at Wadley in 1900, and most of the production formerly went to England, but since 1915 has been marketed in the United States. The smelter and most important mines are owned by Cookson’s, of England, through a subsidiary, the Republican Mining & Metal Co. American interests own other properties in the same region, and during the war a smelter was constructed at San Luis Potosi by the International Mining & Metal Co. In western Sonora, near the Gulf of California, there are deposits of oxidized ores that furnished a considerable part of the ore imported into the United States. These are owned by American capital.

A large deposit of lead-antimony ore (jamesonite) at Zimapan, Hidalgo, owned by The Antimony Corporation, an American firm, has not yet reached the producing stage. Other deposits of possible importance are known in the states of Guerrero, Durango, Sonora, Mexico, Baja California, and elsewhere.

Political disturbances during the last few years have prevented an output of antimony commensurate with the probable capacity of the deposits. Production will probably be maintained in the future, even during periods of low prices.

Bolivia.

—The output of Bolivia was negligible before the war, but under the stimulus of high prices large amounts of high-grade ore were produced in 1915 and 1916. This ore was shipped principally to England, until an embargo was placed on Bolivian ore in 1918. The ore is high grade, that shipped averaging over 50 per cent. antimony, but the veins are small and become unproductive at shallow depth. It is possible that the known deposits have been largely exhausted; and although demand as strong as that of 1916 might result in new discoveries of importance, it is not likely that Bolivia can be an important producer when prices are under normal conditions.

Exports of ore amounted to 17,923 metric tons in 1915 (as against 186 in 1914); to 22,748 tons in 1916; and to 18,340 tons in 1917; but in 1918, for reasons given above, shipments dropped to 3,070 tons. From 75 to 90 per cent. of the ore went to England, and most of the remainder to the United States, except for about a thousand tons a year to France.

Peru.

—During the antimony boom of 1906-1907 a small amount of antimony was produced in Peru. No further production was made until 1915, when 522 tons of high-grade ore was mined. In 1916 the production rose to 1,876 tons of 60 per cent. ore. The 1917 production was 902 tons. Although deposits are known in many parts of the republic, over 90 per cent. of the production has come from the department of Puno, in southern Peru. Up to the present, profitable mining has been possible only during periods of high prices, but the deposits are said to be extensive, and it is possible that improved transportation facilities would result in some production under normal conditions.

Austria-Hungary.

—The most important antimony deposits of the old Austrian Empire are those of Hungary and Bohemia. Others of minor importance are in Carniola, in Austria. The Hungarian deposits in 1913 furnished 11,017 tons of ore containing 1,038 tons of metal; for the rest of Austria the output was 1,270 tons of ore, but only 89 tons of metal. The low antimony content of the Hungarian deposits is compensated by the gold content, and these deposits have produced much more regularly than those of the other parts of the empire. So far as known the reserves are fairly large, but production can hardly be expected to increase greatly.

The productive capacity of both the Hungarian and Bohemian deposits is probably enough to supply local needs in normal times, and allow a surplus for export when economic conditions are favorable. Prior to the war, exports of regulus went to Germany and small amounts of ore were exported to France and England. During the war the Central Empires probably depended largely on the Austro-Hungarian deposits for their antimony supplies. All mines were worked by the government. It is known that certain mines that had been abandoned resumed operations.

France.

—France is the most important antimony-producing country in Europe and also controls important productive deposits in Algiers and Indo-China.

The French deposits are numerous but for the most part small. The most important of these is La Lucette, in Mayenne, where stibnite associated with auriferous pyrite has been mined for many years. This deposit was considered to be approaching exhaustion, but recent work is reported to have developed new ore bodies. The La Lucette company has recently extended its holdings in other parts of France, has bought properties in Algiers and the Transvaal, and in 1911 leased a smelter at Barcelona for the treatment of ores purchased abroad. The La Lucette company is also to some degree associated with the American firm of Antimony & Compounds Co. of America. Undeveloped deposits are known in Tunis, Morocco, French Guinea, and Madagascar.

French control of foreign supplies is not of great importance. In addition to its holdings in the Transvaal, the La Lucette company purchases some foreign ores. In 1913, 4,440 tons of antimony ore was imported from China, and 205 tons from Turkey. Foreign control of French deposits is limited to a few companies. An Italian company, Minière Fonderie d’Antimonio, owns concessions in France and Corsica, from which the production before the war was about 3,500 tons of ore per year. The great Belgian smelting company, Société de la Vieille Montagne, owns the most productive Algerian deposit—the Hamman N’ Bails mine; and an unimportant Algerian mine was, prior to the war, owned by Beer, Sondheimer & Co., a German firm.

In 1913, France produced 20,872 metric tons of ore carrying about 32 per cent. metal content. The smelter output in 1913 was 6,390 tons of regulus and oxide. France is normally an exporter of metallic antimony, the average annual exports during the period of 1910-1914 amounting to about 2,000 metric tons. The principal purchasers were United States, Germany, Italy, Netherlands, and Russia. According to recent information, the surplus production of antimony in France is now so large that the industry can hardly continue to exist on a paying basis unless the producers come to an understanding among themselves. It is clear, however, that to be effective, any agreement among French producers must be either backed by a high protective tariff or must be extended to include their principal foreign competitors.

Germany.

—In Germany the antimony output is too small to affect appreciably the world’s market, but a few localities have possibilities of production when the price of antimony is sufficiently high. One plant in the Eifel district in 1915 was producing 25 to 30 tons of regulus and 60 to 70 tons of oxide a month. There was, however, a production of antimonial lead from the smelters that may amount to 1,000 tons or more of antimony a year. This is derived in part from German ores, especially the lead-zinc ores, and in part from ores of foreign origin.

Germany’s interest in the antimony market is chiefly that of the smelter and middle man. Average annual imports, 1910-1913, were as follows: Ore, 3,668 tons; metal, 3,398; salts, 668. The exports averaged, ore, 566 tons; metal, 331; salts, 1,226. The principal purchasers of metal were the United States and Russia; and of salts Russia and England.

German interest in foreign deposits was not extensive. The Metallgesellschaft seems to have had some connection with an Italian company, the Minière Fonderie d’Antimonio, owning mines in Italy and France, and Beer, Sondheimer & Co. was recorded as the owner of one Algerian mine.

Great Britain.

—Although deposits were formerly worked in Cornwall, Devon, and elsewhere, no antimony has been mined in England since 1892, but before the war England was the chief smelting center of the world, and several brands of British antimony, such as Cookson’s and Hallett’s, had a world-wide reputation. Deposits of considerable importance exist in many of the British possessions.

Cookson & Co., of Newcastle, control mines in the Catorce district, San Luis Potosi, Mexico, and operate a smelter, the output from which was shipped to England for further refining until 1915, when the supply was in large part diverted to the United States.

England, through her smelting interests, has played an important part in the antimony trade of the world. Seven smelters in England refine ore and crude metals that come chiefly from China, but also from Mexico, Australia, and Hungary, and, during the war, in large quantities from Bolivia and Spain. The better British brands have been considered more pure than other grades, and before the war virtually monopolized American markets.

British trading interests have exerted important control both in securing raw material for British smelters and in obtaining markets for British metal. Until 1914 the Chinese Eastern Antimony Co., a subsidiary of Cookson & Co., held contracts for the production of the Wah Chang Mining & Smelting Co., the most important antimony producers in China. In 1914, the Wah Chang Co. established an independent selling agency in the United States. During the great demand for antimony in 1915 and 1916, British interests secured the greater proportion of the output of Bolivian mines and completely controlled the industry of that country.

Italy.

—Italy is the third important antimony producer of Europe. The principal deposits are those in the southern part of the island of Sardinia. During the war, however, the Tuscan deposits were reopened and there has been also a small production from Sicily. The grade of the ore is low, probably on the average less than 25 per cent., and the production, which was 7,609 tons of ore in 1900, had fallen in 1913 to 1,822 tons. War conditions stimulated the industry, and in 1915, 1916, and 1917 the production averaged over 5,000 tons annually, although the imports of metallic antimony also increased, being as follows: 191 tons in 1914; 825 in 1915; 155 in 1916; and 1,247 in 1917.

The low metallic content of the ore, together with the fact that in the Sardinia deposits the calcite gangue makes recovery more difficult, renders it probable that under peace-time conditions and prices, Italy will not become an important factor in the world’s antimony production.

The chief producing company, Minière Fonderie d’Antimonio, was, prior to the war, closely connected with the German Metallgesellschaft, and the richest Sardinian ore went to Germany for smelting. Besides mines in Italy, this company owned several productive deposits in France.

Portugal.

—A small amount of antimony ore, 100 tons in 1912 and 19 tons in 1913, is produced in Portugal. Exports in 1916 exceeded 4,000 tons.

Russia.

—Antimony and argentiferous lead-antimony deposits are known in the Urals and were under development in 1912. Antimony deposits also occur in the Amur province and in many localities in Siberia. In 1915, 67 tons of regulus was imported into England from Russia. Possibly, however, this represents an overland shipment of Chinese material.

Serbia.

—Serbia contains several antimony deposits of considerable promise. The production, however, has been small. No data are available since 1912. The output of regulus and oxide, which amounted to 4,725 metric tons in 1904, had decreased to 297 metric tons in 1912. The greater part of the product was formerly shipped to the United States. Plants at two of the mines are capable of a considerable output should conditions warrant it. It seems unlikely, however, that the Serbian deposits will play an important part in determining the control of the world’s production.

Spain.

—Antimony deposits are known in many localities in Spain. Most of these are irregular and have been repeatedly worked and abandoned. A few, however, offer some promise of a continued output. The annual production has scarcely exceeded 500 metric tons of ore, even under the stimulus of war conditions (516 tons in 1916, and 502 tons in 1917). The smelter production in 1916 was 425 tons. Shortly after the outbreak of the war there were three smelters, the most important being operated by the French company, La Lucette.

Before the war Spain imported annually 800 tons of antimony ore from France, and over 100 tons of salts of antimony was exported annually to Germany.

Borneo.

—British Borneo was formerly a producer of considerable importance, and much ore was exported between 1859 and 1894, mainly to England. The deposits then remained idle until 1914, when 870 tons of ore was exported; in 1915 the exports amounted to about 360 tons. It is probable that no important output at peace-time prices is to be expected, although the country is largely unexplored. The Borneo company (British) seems to have been the principal if not the only producer.

China.

—With all her vast mineral resources China has been able to obtain an important position in the world’s markets with regard to but few metals. Of these antimony is the most striking example, for since 1908 over 50 per cent. of the world’s total antimony production has come from China. In 1913 the output was estimated to be the equivalent of 10,800 tons of metallic antimony, that of the whole world being about 20,000 tons. The Chinese industry being well-established, it was able to respond rapidly to the great demand of the war. Exports increased from 14,361 short tons of regulus and crude antimony, and 4,795 tons of ore, in 1913, to 38,142 tons and 8,667 tons, respectively, in 1917.

Antimony is found over widely scattered areas in the central and southern provinces, but chiefly in the provinces of Hunan, Yunnan, Kweichow and Kwangsi. In Hunan the deposits have been most extensively exploited, probably 90 per cent. of the total production of China coming from the region about Changsha, the center of the smelting industry. Here, in the Hai-Keng-Shan district, in 1915 about 70 companies mined antimony along the outcrop of the deposits. The ore, remarkable for its purity, occurs as pockets and bunches, mainly of stibnite, in a flat bed of dolomitic limestone. Several local smelters produce liquated sulphide, and the output of the district is about 1,000 tons monthly of crude antimony averaging about 70 per cent. metallic antimony. All regulus manufacture is controlled by the Wah Chang Co. In the Panshi district the ore occurs as fissure veins in slates, shales, and quartzites. The output consists of about 400 tons monthly of 30 per cent. ore, all of which is shipped to Wah Chang Co. at Changsha for treatment.

The only district in Yunnan where antimony is dealt with commercially is near Chihtsun on the Tongking-Yunnan Railroad. The Pao Hua Co., connected with the Wah Chang Co., owns a French-constructed plant and produces high-grade regulus.

The Wah Chang Mining & Smelting Co. virtually controls the production of antimony ore, regulus, and crude in the Province of Hunan. This company operates smelters in Changsha and owns low-grade mines. It possesses a complete monopoly, granted by the Peking government, for the manufacture of regulus in Hunan and owns the patent rights in China for the Herrenschmidt furnace, the most successful means of reducing low-grade antimony ores. The mines themselves are mostly native-owned, and worked in a small way.

Prior to the war, exports of Chinese antimony were chiefly in the hands of English, French, and a few German firms. The New Chinese Antimony Co. (also known as the Chinese Eastern Antimony Co.) a subsidiary of Cookson & Co., of England, held a contract for the entire output of the Wah Chang Co. This contract was broken shortly after the war began, although the Wah Chang Co. paid a percentage on all sales to the New Chinese Antimony Co. for a year thereafter. The Wah Chang Trading Co. was organized as a direct selling agency in New York, and has established a large business in this country.

With present high scale of wages for labor, and prices for material, it is difficult to see how this country can compete with China in the production of antimony. Adverse exchange conditions due to the high price of silver have probably nearly doubled the cost of production in China and wages in that country have advanced. In spite of this, however, China can manufacture antimony far more cheaply than is possible in Europe or America; and probably, also, more cheaply than in Japan.

Chinese antimony suffered from lack of advertising before the war, being largely excluded from this country by the British metal, but has now become firmly established in our markets, and its quality has proved equal to the best English grades.

India.

—Since the war, small amounts of antimony have been produced in Burma and Mysore. The total Indian ore production was 1,040 tons in 1916 and 130 tons in 1917. The most productive region was the Amherst district of Burma. Here the ore reserves are said to be considerable, but the inaccessibility of the district has made production impossible except at high prices. The production from Mysore was only 26 tons in 1916.

Indo-China.

—There are productive deposits of possible future importance in French Indo-China. In 1916 these produced 1,437 tons of antimony ore with a metal content of 642 tons. Smelters were operated by the firm of Schön & Rhay, and both native and Chinese ore was treated. In 1914 and 1915, 883 and 630 tons of antimony ore were exported to France.

Japan.

—Very little antimony ore has been produced in Japan since the development of the Chinese deposits, although, as in most other countries, there was a renewed development during the war. The smelting of Chinese ores in Japan has become extremely important; and the smelter production, which was only 32 tons in 1914, rose to 8,189 tons in 1915, and to 10,633 tons in 1916. It was 6,562 tons in 1917. The production of metal and crude from domestic ores was only 186 tons in 1915 and 286 tons in 1916. It is probable that as long as cheap ore is available in China little production from Japanese deposits is to be expected.

Japanese ownership in Chinese mines is probably small, as practically all Chinese antimony bought by Japan has been purchased in the open market in the form of crude and ore. Since 1914 Japan has played an important part in the smelting of Chinese ore and matte, and in this regard has ranked second only to China. Prior to that time, however, production was insignificant. China is now in a position to supply direct the major part of the world’s requirement of metal, having largely extended her facilities for treating antimony ores, and it is doubtful whether Japanese smelters will long be able to compete successfully.

Turkey.

—The antimony production of the Turkish Empire comes from Eastern Asia Minor in the vilayets of Brussa and Smyrna. The productive district of Allchar, formerly in European Turkey, passed to Serbia after the last Balkan War. The deposits seem to be rich and capable of greater development. Bad government, lack of transportation facilities, and excessive export duties seem to have retarded production. Some mines were the property of the Sultan, and development was hindered by excessive royalties. Most of the mines seem to be owned or leased by Greeks. Deposits of antimony ores associated with argentiferous lead ores are reported in the vicinity of Karahissar, in Armenia. In 1914 the concession for these was held by the Asia Minor Mining Co., presumably a British corporation. Undeveloped deposits of possible importance occur in the islands of Mytelene and Chios, now in Greek ownership.

Little information is available as regards production. In 1911 the Djinli Kaya mine produced 1,500 tons of 50 per cent. ore. The 1912 production of Asia Minor is reported as 677 tons of ore. Exports of antimony ore from Turkey to Great Britain were as follows: 1910, 303 (metric) tons; 1911, 773 tons; 1912, 1,108 tons; and in 1913, 408 tons. Some ore was also shipped to Austria, and, in 1913, 205 tons went to France. It seems probable that, given good government and improved transportation facilities, an increased production could be obtained from the region even at peace-time prices, for according to the best available information the deposits are large and much of the ore is high grade.

Algiers.

—The Algerian deposits are probably capable of considerable development, as is shown by the response to the increased demand in 1915 and 1916. The ores are nearly all oxidized and contain various rare antimony minerals. Prior to the war the chief production consisted of antimonate of iron, mined together with lead and zinc ores at Hamman N’ Bails. During the war large deposits of oxides were developed and were supplying antimony at the rate of 300 tons per month during the early part of 1918. In 1912, there was produced 4,661 tons of ore; in 1913, 582 tons; in 1914, 1,100 tons; in 1915, 9,022 tons, and in 1916, 28,473 tons. Apparently the ore produced carries around 40 per cent. antimony (metallic content).

The mine of Hamman N’ Bails is owned by the great Belgian smelting company, the Société de la Vieille Montagne; and the La Lucette company (French) owns the productive Ain Kerma oxide deposits. Prior to the war, the German firm of Beer, Sondheimer & Co. was listed as the owner of one of the less important mines.

British South Africa.

—Several antimony deposits are known in British South Africa, seemingly the most promising being those of the Murchison Range in the northern Transvaal. Here auriferous stibnite occurs as veins and replacements in limestone over a considerable area. The ore as mined carries 3 to 6 dwt. gold and 7 to 10 per cent. antimony. Sales and shipments of concentrated and crude antimony were as follows: 1913, 48 tons; 1914, nothing; 1915, 91 tons; 1916, 722 tons; and 1917, 617 tons.

The principal mine of the range, the United Jack, was purchased in 1917 by the La Lucette company (French). In 1916 there were four producing mines in the district. The antimony deposits of the Steynsdorp district, near the Swaziland border, were under development in 1916, and antimony deposits are known in the Forbes Reef district in Swaziland. Antimony ores are found over a considerable part of southern Rhodesia, and this district would probably be capable of a considerable output with better transportation facilities and continued high prices. Ore production in 1916 and 1917 was 38 and 15 tons. Some of the mines, such as the Hope Fountain, near Bulawayo, are chiefly gold producers, antimony being a by-product.

—The only antimony-producing district of any importance in Australia is the Costerfield district of Victoria. Here stibnite and antimony oxides occur in quartz veins cutting Ordovician slates. The antimony concentrates, which average about 48 per cent. antimony, and also contain about 2¹⁄₂ ounces of gold per ton, are shipped to England. The annual production is rather regularly 2,500 to 3,000 tons of concentrates.

Table 32.—World’s Production of Antimony (1912-1917)
Approximate recoverable metal content of ore produced, metric tons; antimonial lead ores not included

The Hillgrove district, in New South Wales, was formerly of considerable importance, the highest annual output being 2,450 tons of ore in 1906. Recent production has been slight, and although a very large increase took place with the stimulus of war prices, the 1917 production was valued at only about 5 per cent. of that of Victoria. Insignificant amounts of antimony ore have recently been produced in Queensland and Western Australia. New Zealand yielded a small amount during the boom of 1906 and 1907, but no production is recorded since 1910.

Imports of antimony ore into Great Britain from Australia in 1915 amounted to 3,854 tons.

Statistics of production (1912-1917) are given in the table preceding.

—The United States is the largest consumer of antimony in the world, requiring under normal conditions between 7,000 and 8,000 tons of new metal, most of which, before the war, came from England. The consumption during the war was about double this amount, and was derived chiefly from the Orient, South America, and Mexico. The United States must remain dependent upon foreign sources for its supply, unless a much higher tariff is placed upon imports. Even under such conditions it is doubtful whether domestic mines would prove adequate to supply more than a small part of the country’s needs.

Chinese and Japanese antimony has largely replaced the British product since 1914 and has become so well established that it will probably continue to hold American markets. Chinese antimony in particular has shown itself equal in every way to the best British grades. With a somewhat higher level of prices the importation of ore from Mexico and South America may be undertaken by reducing plants in this country, as the experience gained by several companies during the war has made possible the production of high-grade metal.

—No figures as to the actual consumption of antimony in England are available. Judged from a balance of imports and exports, the normal consumption is about 4,500 tons annually. During the war consumption was enormously increased for the manufacture of munitions. English smelters are entirely dependent on foreign ores, most of which in the past have come from China, with smaller amounts from Mexico and Australia. The position of the industry, at least in so far as export trade is concerned, is threatened by the strong position of the Chinese industry acquired during the war, as represented particularly by the activities of the Wah Chang Mining & Smelting Co. Two-thirds of the English antimony exports went to the United States before 1914. It does not seem probable that England will be able to fully recover this market, now dominated completely by Chinese and Japanese antimony.

—France is the only world power that possesses important resources of antimony within her boundaries. Including her Algerian mines, she is entirely independent of outside supply. Inasmuch as certain of the French deposits contain important amounts of gold, and the principal Algerian mine contains lead and zinc, the production of antimony in France will probably continue to be of some importance, and it is probable that she will continue to export antimony as before the war, though probably to a less extent.

—Germany, prior to 1914, consumed about 20 per cent. of the world’s annual output of antimony. Her own resources of antimony are insignificant, and German interests in foreign deposits have not been widely extended but were rather those of smelter and middleman, raw material being drawn chiefly from China, and metal and salts being exported to the United States, Russia and Great Britain. During the war Germany drew largely upon Hungary for antimony supply, but it is known that this source could not adequately meet the demand.

—Japan’s actual consumption of antimony has never been large and before the war was confined largely to the production of “white metal” boxes, trays, and other articles. During the war her importance in the antimony trade rested upon her ability to supply a large part of the needs of the Allies, principally Russia, and later the United States and Canada. How long after the war she will be able to retain her position is uncertain. Favorable freight rates to Japanese shippers, and the fact that the present high price of silver and the consequent exchange conditions affect adversely Chinese production may enable Japan to continue a factor in the antimony trade.

Owing to the very high prices prevailing for antimony during 1915 and 1916, caused by a greatly increased demand for antimony for the manufacture of munitions, several countries became large producers. The most important among these were Bolivia, Mexico, and Algeria, but Victoria and the United States, Peru, Burma, and Spain all contributed substantial amounts. With the possible exception of Algeria—whose principal mines yield considerable lead and zinc and are situated near to French reduction plants—and of Mexico, none of these countries will be important factors in the production of antimony at the usual low prices prevailing for that metal.

The sudden ending of the war found the belligerents with large stocks of antimony on hand, the English holding, according to figures published by the British Ministry of Munitions on March 1, 1919, 4,325 long tons of regulus. There is reason to believe that the other Allies had stocks of the same order of magnitude, and if so there must have been about a year’s supply available on April 1, 1919, as the 1913 consumption of antimony amounted to only about 20,000 tons. In addition there were large supplies of alloys and antimonial lead available and more will undoubtedly be obtained by salvage operations. It may be expected, therefore, that until these are absorbed the production of antimony will be even less than that of pre-war years. At present there is little inducement for mining. Costs of mining have increased everywhere. China, the largest producer, faces a particularly difficult situation, for the higher price of silver has resulted in doubling costs of labor and local supplies. If silver prices remain high after the demand for primary antimony has recovered, the other antimony-producing countries, not on a silver basis, will have a corresponding advantage over China in the matter of production.

The peace-time consumption of antimony is limited rather by the relatively restricted uses to which antimony is put than by any lack of potential supply. As a consequence, steady production has been maintained only from those districts in which working expenses are low and markets readily available, or in which the deposits contain other metals of value. Modern warfare, however, creates a special use for antimony—in the manufacture of shrapnel—which requires many times the amount of antimony necessary for ordinary peace uses. In the case of each of the three important wars of the last twenty years, the Boer War, the Russo-Japanese War and the Great War, the curves of antimony prices and production have risen sharply in accordance with the demand, and have fallen as rapidly after the need for munitions was past.

China has for long been the most important source of antimony and will doubtless retain that position for many years. Steady though less important production has been maintained in France, Austria-Hungary and Mexico, while several other countries produced important amounts as a result of the largely increased demands of the war. Chief among these were Bolivia, Algeria, and Australia.

England dominated the antimony market prior to 1914 through her large smelting interest, trade agreements in the Orient, and selling agencies in America—the principal consuming country. Since that time, however, Chinese interests have become independent, and Japan has become of importance in the antimony smelting and trading field.

The United States possesses limited antimony resources which can be exploited only at very high prices, and is dependent almost entirely upon outside sources of supply. In the past this supply has been drawn largely from England, but more recently from the Orient and Mexico.

Germany has insignificant antimony resources of her own, and depended for her supply during the war upon the Hungarian deposits, which were apparently inadequate to meet the demands. Her interests prior to the war were chiefly those of the smelter and middleman, and did not extend very largely to foreign deposits.

The United States, France, Germany and Great Britain normally consume 85 per cent. of the antimony of the world, and of these France alone is independent of foreign sources of supply.

The antimony trade of the world is largely controlled by a few companies, of which the most important are: Cookson’s (British), Wah Chang Co. (Chinese), and Société de La Lucette (French). The Mitsui Co. (Japanese), largely through shipping interests, has a considerable share in the Chinese and Japanese antimony trade.

CHAPTER X MOLYBDENUM By R. B. Moore — USES OF MOLYBDENUM — GEOLOGICAL AND GEOGRAPHICAL DISTRIBUTION — Australia and Norway. — North America. — RESERVES — TREATMENT OF ORES — POLITICAL CONTROL — COMMERCIAL CONTROL — POSITION OF LEADING COMMERCIAL NATIONS — SUMMARY

Molybdenum is used in the manufacture of ferro-alloys for making steel. As wire, it is used for supporting the filament in incandescent electric lamps. The wire is also employed for winding electric resistance furnaces and for this use has proved cheaper and better than platinum because of the quicker heating and higher temperatures attainable. The metal has been successfully substituted for platinum and for platinum-iridium in electric contact-making devices. Molybdenum compounds are used in chemistry, particularly ammonium molybdate for the determination of phosphorus. Fast colors in a variety of shades may be produced on leather by employing molybdenum tannate in conjunction with logwood extracts. It has been employed for color glazes in porcelain and in coloring silks and rubber.

The addition of molybdenum to steel increases the elastic limit without diminishing the ductility. Molybdenum can be substituted for a certain percentage of tungsten in high-speed steel, as a rule one part of molybdenum taking the place of two to three parts of tungsten.

Up to about 1916, practically all of the molybdenite concentrates produced came from Queensland, New South Wales, and Norway. Shortly after the opening of the war, interest was shown in the production of molybdenite in Canada, principally in the provinces of Ontario and British Columbia. During 1917 and 1918 there was a great deal of interest in the United States in molybdenum ores, and at the present time this country can probably produce molybdenite concentrates in quantity equaling if not exceeding the rest of the world put together. Some molybdenum is produced by Spain and Peru.

—The first official record of a production of molybdenite in Queensland was in 1900, when the output amounted to 12.3 short tons of high-grade material. The production gradually rose to 119 tons in 1906, and has not varied materially since that date, although the selling prices for concentrates increased considerably. The bulk of the material was mined at Wolfram Camp, in the Chillagoe field, 120 miles southwest of Cairns, in Northern Queensland. The mines at Bamford, in the same field, are credited with a small output. With the molybdenite ores are bismuth-tungsten ores, so that all three metals are produced.

The production of molybdenite was first reported in New South Wales in 1902; in that year the output was 17 short tons. The total output to the end of 1914 was 498 short tons, valued at $264,000. The chief producing molybdenite mines are at Whipstick, in the Pambula division, at Kingsgate, in the Glenn Innes division, and near Deepwater, in the Deepwater division. Molybdenite is also being produced at Rocky River, in the Tantafield division, and in the Bathhurst division. The production at all of these localities has not been large—in no one year exceeding 100 tons of concentrates.

In Norway, the production of high-grade molybdenite concentrates has averaged about 30 tons per annum since 1902. In 1906, an output of 1,129 short tons was reported. This probably refers to ore mined and not to concentrates produced.

The chief molybdenite districts in Norway are the provinces of Lister, Mandal, and Nedenes, on the extreme southern end of the peninsula. The district of Fjotland, in the former province, is probably richer in molybdenite than any yet discovered in Norway. A mine at Knaben, in this district, has been the largest and probably the only successful producer in Norway. This mine, owned by George G. Blackwell & Sons, of Liverpool, England,[94] has made an average output of about 25 short tons per annum.

Table 33.—Production of Molybdenite in Queensland, New South Wales and Norway

The production of molybdenite in Queensland, New South Wales and Norway, by years, is shown in the preceding table.

Figures for more recent years indicate the total production in Australia of about 330 short tons per annum and 110 short tons in Norway in 1916. In 1917 the output in Norway was three times the 1916 figures.

—As already stated, the chief molybdenite deposits in Canada are in the provinces of Ontario and British Columbia. They are low grade and of course need concentration. The Canadian and British governments have been much interested in the concentration of these ores and the Canadian government has a mill engaged in experimental work and in commercial concentration. The Department of Mines has spent a good deal of time in experimentation, believing that molybdenite has an important future in metallurgy.

The production in 1917 was about 80 short tons of high-grade concentrates and was undoubtedly larger in 1918.

Canada when properly prospected may produce a good deal more molybdenite than now.

In the United States are a very large number of small molybdenum deposits, scattered over the western states from Washington to Arizona and from Colorado to California. There are two common minerals—molybdenite, or molybdenum sulphide, and wulfenite, or lead molybdate. Generally speaking, molybdenite is found in the northern states, and wulfenite in the southern states, but this rule is not without exception. In Arizona and New Mexico, the principal mineral is wulfenite, but there are some fairly large deposits of molybdenite, probably the best being at the Leviathan mines, in Copper Canyon, Mohave County, Arizona. This is the only molybdenite deposit that is being worked in New Mexico or Arizona. It is in the Cedar Valley mining district about three miles southeast of Copperville and about 25 miles east of Yucca. This ore carries a good deal of copper, as well as small traces of gold and silver. Some analyses have shown 2 or 3 per cent. MoS₂ and 1¹⁄₂ to 2 per cent. copper with 0.02 ounce of gold and 1 to 4 ounces of silver per ton. The percentage of molybdenite is undoubtedly above the average, which does not exceed 1 per cent. The country rock is medium-grained gray granite, consisting of quartz, feldspar, biotite, muscovite and small amounts of other accessory minerals, such as zircon and apatite. The company has erected a mill and has succeeded in making a satisfactory separation of the copper from the molybdenite.

The largest possibilities in Arizona and New Mexico are in mining wulfenite. This mineral is widely scattered over these two states, especially Arizona, and is, to a great extent, associated with vanadinite. One of the greatest difficulties in concentrating wulfenite has been the separation from vanadinite. The Bureau of Mines has worked on this problem for some time with partial success.

The most important deposit of wulfenite is at the Mammoth and Collins mines, in Pinal County. They were originally gold mines, and when the value of molybdenum became evident, Colonel Randolph, owner of the Mammoth mine, decided that it would be worth while to run the tailings dump for wulfenite. He converted his mill to this purpose, and not only ran the Mammoth dump but also the dump at the old Yuma mine, in Pima county. The total amount of concentrates produced by Colonel Randolph and others in the vicinity during the three years 1916 to 1918 are probably represented by 1,000 to 1,200 tons of wulfenite concentrates. While these operations were going on, they represented practically the only production of molybdenum concentrates in this country except on a very small scale. One other operating company is the Rowley Copper Mines Co., Gila Bend, Arizona, the ore being wulfenite and the principal impurity barite. The company has succeeded in making satisfactory concentrates, which carry, however, a considerable amount of barite. The Golden, Colo., station of the Bureau of Mines has run some tests on this concentrate and has made a partial separation of the barite and wulfenite.

Molybdenite is found in a considerable number of places in Colorado, Montana, Washington, Nevada, Utah, Texas and other western and northwestern states, but the largest occurrence is in Colorado. Generally speaking, the individual deposits in the West are not large enough to warrant the building of a mill for any one of them, and as the deposits are widely scattered, it is difficult to find a place where a custom mill could obtain a sufficient amount of ore. This is one of the chief difficulties in producing a large tonnage of molybdenite concentrates, outside of Colorado.

Probably the largest deposits of molybdenite in the world are at Climax, Colorado. These deposits are on the southwestern slope of Bartlett Mountain, Summit County, about 15 miles from Leadville. Outcrops are practically continuous across the whole length of the mountain and at places are one hundred to two hundred feet thick. The ore is rather granular and not flaky molybdenite, the average grade running about 8 per cent. MoS₂.

There are two operating companies, the Climax Molybdenum Co., a subsidiary of the American Metal Co., of New York and Denver, and the Molybdenum Products Co., of Denver. Both of these companies have erected mills having daily capacities of 200 tons. The mill of the American Metal Co. started continuous operation about March, 1918, and that of the other company was completed shortly afterwards. Both companies claim that they can enlarge the capacity at short notice. The writer was in the mine of the American Metal Co. Evidently a considerable part of the mountain is molybdenite, and without doubt, a very large tonnage can be produced. The Jackling interests recently acquired the adjoining properties owned by the Pingree Mines Co., but in 1918 had not built a mill or carried out any serious development work.

Another very large group of deposits of molybdenite lies near Empire, Clear Creek County, Colorado, on the eastern slope of Red Mountain, at an altitude of about 11,000 to 12,000 feet. The deposits are 14 miles from the Empire station of the Colorado & Southern Railroad and are owned by the Primos Chemical Co., of Primos, Pennsylvania. The ore-bearing bodies consist of three veins of low-grade ore. The ore zone, that is, the ground included between the footwall of Vein No. 1 and the hanging wall of Vein No. 3 where cut by the tunnel, is about 200 feet wide. The veins vary greatly in width and are not particularly well defined, thin veinlets and stringers of ore running into the walls. The Primos Chemical Co. has worked these mines off and on for several years. About three years ago it built a mill near the mine, but production has been rather intermittent. This company has probably used all of its concentrates for making ferromolybdenum at its own works in Primos, Pennsylvania.

A small mill has been erected at Pitkin, Colorado, in connection with the mine at that place owned by the Pennsylvania Molybdenum Mines Co., of Johnstown, Pennsylvania. A number of other deposits of considerable interest are found in Colorado, especially around Breckenridge, Summit County. Here the pegmatite veins consist largely of muscovite and quartz, with some feldspar, and carry biotite, chalcopyrite and accessory minerals. The difficulty here is to separate the molybdenum from the copper minerals and also from the mica, most of which floats with the molybdenite.

Most of the developed molybdenum deposits of Mexico are in the State of Sonora. In the Sahuaripa district of eastern Sonora, the mineral occurs with scheelite in rich pockets containing very large pieces of pure mineral. Some molybdenum ore has been shipped from the Montezuma copper district to the Empire Smelting & Refining Co., of Deming, New Mexico. Molybdenum is reported in several other Sonora localities. Near Coyame and Marquez, northeastern Chihuahua, the mines of the Compañia Minera Aurora y Anexas produce molybdenum ore. Wulfenite is found abundantly with the lead ore of the Cuchillo Parado mine in the same district. The Jibosa copper mine of the American Smelters Securities Co., near Jimenez, Chihuahua, seems to carry considerable oxide of molybdenum, molybdite. It is not commercial at present.

Molybdenite deposits are also reported in the states of Sinaloa, Oaxaca, Hidalgo, and Jalisco.

As the production of molybdenum ores in the past in all countries has been relatively small, probably none of the deposits have been worked out and an increased output can be obtained. This applies particularly to the United States. All of the work that has been done so far has been on an experimental basis, and possibly the only mine whose tonnage will be decreased by past production is the Mammoth mine, near Mammoth, Arizona, and there is no certainty that this mine can not continue to produce as much for some time in the future as it did during its period of operation. Just what production can be obtained in the United States is somewhat uncertain, but it is probable that the deposits at Climax, Colorado, will yield at least one thousand tons of ore a day for several years and possibly for a good many years. The deposits of the Primos Chemical Co. near Empire, Colorado, are also extensive and should give a large output for some time to come. The rest of the deposits mentioned are small compared with these two, but the total production of all of them might be large, were a steady market assured and custom mills erected.

In concentrating wulfenite ores some form of table concentration, with the addition of slimers, is generally used. The metallurgical treatment of the concentrates varies and is still very much in the experimental stage. There is opportunity for the development of a process that will give the patentee a considerable advantage over competitors. The Bureau of Mines has been working on this problem and has recently devised a method that seems to be as efficient as any other and possibly has some additional advantages.

In the treatment of molybdenite the same methods are almost universally used. First the ore is crushed to the required fineness and the molybdenite is separated by flotation, largely oil flotation. The metallurgy of the concentrate, now more or less standardized, involves roasting the concentrate to the oxide and treating this oxide in an electric furnace for the production of ferromolybdenum. With small improvements, this practice is likely to be maintained for some time to come.

The political control of the molybdenum deposits of the world is determined by the geographical location. At present most of the known deposits are controlled by the United States and Great Britain, the latter controlling those in Canada and Australia. The British and Canadian governments actually have a government mill in Canada.

The Knaben mines, in Fjotland, the most famous and probably the only successful molybdenum mines in Norway, were acquired in 1905 by an English company, the Blackwell Developing Corporation. Later a newly organized Norwegian company, with head office in Christiania, took over the mines at a price of 2,500,000 crowns.

In Mexico the large molybdenum deposit in the Sahuaripa district of eastern Sonora is owned by George Fast, of Douglas, Arizona. The Lucky Tiger-Combination Gold Mining Co., of Kansas City, Mo., (American) owns the deposits in the Montezuma district. Another American company has acquired deposits near Poza, Sonora, about 20 miles north of Hermosillo. A deposit located 35 miles from the port of Topolabampo, northwestern Sinaloa, is owned by an American. The Compañia Minera Aurora y Anexas, operating molybdenum mines near Coyame and Marquez, northeastern Chihuahua, is owned by the Madero estate. The ore has been shipped to Leonard Worcester, El Paso, Texas, agent for the estate and also purchaser for L. Vogelstein & Co., New York, formerly a branch of the German metals combine.

In the United States, during the war the claim was made a number of times, both privately and in the press, that German interests were trying to obtain control of the molybdenum deposits of the country. This was due to the fact that the American Metal Co., which operates at Climax, Colorado, as the Climax Molybdenum Co., and which has some other molybdenum deposits, was formerly controlled by German interests. It is true that the majority of the stock of the American Metal Co. was owned in Germany, but Mr. Palmer, the Alien Property Custodian, took charge of this stock, and the affairs of the American Metal Co. were readjusted to changed conditions. The principal stockholders of the Primos Chemical Co. were four brothers by the name of Boericke. Before the war they had strong German connections, but outside of their deposits at Empire they made no special effort to get large molybdenum holdings in this country and did not seek to get a combination of any of the operating companies. The Primos Chemical Co. has since 1919 been taken over by the Vanadium Products Corporation, affiliated with the Bethlehem Steel Corporation. The Molybdenum Products Co., Denver, Colorado, which owns a part of the molybdenum deposit on the slope of Bartlett Mountain, near Climax, and operates a 200-ton mill, is a subsidiary of E. J. Longyear Co., exploring engineers, of Minneapolis, Minnesota. Both companies are owned by American stockholders.

In Canada and Australia it is certain that no one large interest has control, as the ore comes from a number of more or less independent small mines.

A large number of patents have been issued in connection with the concentration and metallurgy of molybdenum. None of these is vital to production; most are valueless, and even those that have a distinct value do not necessarily give control to the owner of the patents or secret processes.

In order to insure a steady demand for molybdenum, the prime requisite is a definite knowledge of the properties and uses of molybdenum steel. In the past this has been lacking, and at present it is not possessed by the majority of operators and steel makers. Europe should assist materially in supplying this deficiency. Molybdenum steel at the present time is in the same position as vanadium steel was a number of years ago—it is on trial. This uncertainty caused a very decided slump in the demand for molybdenum concentrates in the spring of 1918. A control of molybdenum is more likely to come through the manufacture of molybdenum steel than through processes connected with the production of concentrates or ferromolybdenum.

At present the United States has the largest potential supply of molybdenum ores of any country in the world. In addition it has three of the largest and most modern mills that are handling ore from any molybdenum deposit. It is in a favorable position to equal or surpass, for some time, any other country, in output of molybdenum concentrates.

Before the war Great Britain, through political control of the Australian and Canadian deposits, was the world’s leading producer. Some molybdenum came from Norway, but the amount was small as compared to the output of Australia, Norway producing in 1913 only 13 short tons and Australia 162.6. In both Canada and Australia the known deposits have not been worked to capacity and new deposits will probably be discovered with proper prospecting, so that the future molybdenum production under British control promises to increase. The Canadian and British governments are much interested in the development of the molybdenum resources of the dominion.

France is entirely dependent upon England and the United States, although it might be able to get a small amount of concentrates direct from Norway.

Germany was much interested in molybdenum before the war. During the war it probably did not import any molybdenum concentrates at all, and as the world production before that time was small it is not likely that there was any reserve on hand in the empire in 1919.

Japan has no molybdenum deposits as far as is known, and probably is not specially interested at present in the use of this metal.

The distribution of the chief molybdenum deposits of the world is shown in Plate VII.

Plate VII.—Geographical distribution of the molybdenum deposits of the world. By R. B. Moore.

Molybdenum commands attention because of its growing importance as a steel alloy metal. Although the metallurgy and properties of molybdenum steels are not thoroughly understood and their use is not widespread, especially in this country, accumulating evidence indicates that molybdenum will eventually become one of the common alloy metals. It is used in the form of wire as supports for incandescent light filaments and in electrical apparatus, and may become essential in the manufacture of special steels. It cannot be easily replaced in chemistry, and for its other applications it is better and cheaper than other materials.

Up to 1915 practically all of the molybdenum produced came from Queensland, New South Wales, and Norway. At present more important deposits are being developed in Ontario, Quebec, and British Columbia, Canada, and in Colorado, Arizona, New Mexico, and other western states. The mineral is widely distributed and the discovery of additional deposits is likely if the demand is sufficient to encourage prospecting. The United States has deposits large enough to meet all domestic needs and also to produce a surplus for export. Some molybdenum is obtained from Mexico, Peru, and Spain, but the United States, Great Britain (Canada and Australia), and Norway control the important deposits.

The largest molybdenum deposit in the United States, located at Climax, Colorado, is owned by the Climax Molybdenum Co., a subsidiary of the American Metal Co. (formerly German), and by the Molybdenum Products Co., of Denver, an American company. Other deposits in Colorado are owned by the Primos Chemical Co., a company that had strong German connections before the war, but has been taken over by the Vanadium Products Corporation, an American company. Other producing deposits of the United States are owned by American citizens.

The Knaben mines, the most important in Norway, have been owned since 1905 by an English company, but, according to a report, they have been acquired by a Norwegian company. A number of the deposits of northern Mexico are owned by Americans. Others are owned by the Madero estate (Mexican). The Canadian and Australian deposits are controlled by small, independent operators. Both the United States and Great Britain have ample supplies of molybdenum; France produces none and is dependent upon other countries; Germany, which was much interested in molybdenum before the war, probably has no large stocks on hand.

CHAPTER XI RADIUM AND URANIUM By R. A. F. Penrose, Jr. — Uses of Radium. — Uses of Uranium. — ORES OF RADIUM AND URANIUM — General Statement. — Carnotite. — Uraninite and Pitchblende. — Other Ores. — GEOGRAPHICAL AND GEOLOGICAL DISTRIBUTION OF RADIUM AND URANIUM — RADIUM AND URANIUM RESOURCES OF THE UNITED STATES — General Statement. — Colorado and Utah. — Production. — RADIUM AND URANIUM RESOURCES OF EUROPE — Austria. — England. — Germany. — Other Localities. — RADIUM AND URANIUM RESOURCES OF AUSTRALIA, INDIA AND AFRICA — Australia. — India and Africa. — PROSPECT OF FUTURE DISCOVERIES OF RADIUM AND URANIUM ORES

Radium is a metal and is a product of the disintegration in nature of the metal uranium. Both radium and uranium are elements. Radium has been isolated in its metallic state, but is not used in that form and is known better in the form of its salts, among the most important of which, so far as their uses are concerned, are the bromide, chloride and sulphate.

Wherever uranium occurs in nature, radium is associated with it in certain definable quantities. Uranium can contain, however, only a certain maximum amount of radium at a time, and when it has reached this stage, the radium and uranium ratio is said to be in equilibrium. In this condition the amount of radium per gram of uranium has been calculated by Rutherford to be 3.4 × 10⁻⁷ gram. This corresponds to 1 gram of radium element to about 3,000 kilograms of uranium element, or 1 part of radium element to about 3,000,000 parts of uranium element. Uranium minerals as mined are usually impure and carry only a small percentage of uranium elements, so that the ratio between radium and the crude uranium ore may be 1 to several or many times 3,000,000.

The production of radium from uranium is usually stated in milligrams or grams, and even in the richest ores there is usually only a small fraction of a gram to a ton, while in the ordinary lower-grade ore there are only a few milligrams to a ton, corresponding to a small fraction of a grain to a ton. Less than twenty years ago it was estimated that probably not one gram of radium element in the form of its refined salts had been extracted in the world. Today a great many times, perhaps a hundred times or more, this amount has been extracted and is in use. The annual production of radium today in the world is probably several grams. The annual production of uranium in the world is probably several hundred pounds.

The unique position of uranium as the source of radium in nature makes it necessary to discuss both materials together.

—Radium is a heavy white metal which is very unstable, and alters rapidly in the air. It is not used in its metallic stage but only in the form of its salts. A few years ago these salts were supposed to have a general beneficial effect in the treatment of cancer and other malignant growths, but more recent investigations seem to confine their influence to only certain forms of these afflictions. Their influence in other diseased conditions is often very marked, but the full extent of the field of usefulness of radium for medical purposes has not yet been very clearly defined.

In recent years radium has been applied to other important purposes, especially in luminous paint for watches, clocks, compasses and other instruments; and this use has so greatly increased in recent years, especially for military purposes, that it now consumes more radium than is used in medicine. Radium salts are more or less luminous when seen in a darkened room, and this quality is often increased by the admixture of certain other materials, notably zinc sulphide. Hence their value in luminous paints. Radium salts also cause certain minerals to fluoresce, notably the zinc minerals willemite and sphalerite. In Germany, where radium during the war became scarce on account of the shortage of the ores from which it is extracted, radium salts are said to have been preserved for medical purposes, and mesothorium and other radioactive substances used in making luminous paints.

—Uranium is a heavy white metal, which slowly tarnishes on exposure to the air. The chief use of uranium today is as a source of radium. For many years before the discovery of radium, however, uranium compounds were used in a small way in coloring glass and porcelain, in photography, in reagents for chemical analysis, in mordants for dyeing and for other minor purposes. The use of uranium metal in small quantities in steel manufacture has been tried with some degree of success.

—The principal uranium minerals at present known in nature, which are therefore the principal sources of both uranium and radium, are carnotite and uraninite, with the impure amorphous form of uraninite known as pitchblende. Torbernite, autunite and some of the rarer uranium minerals have produced a little radium and uranium.

Carnotite and uraninite or pitchblende as mined for ores are generally more or less mixed with other materials and are rarely found pure. The uranium in the ores is usually stated commercially, for convenience, in the form of the uranium oxides represented by the formula UO₂ + 2UO₃, briefly expressed as U₃O₈. Most carnotite ore varies from 1 per cent. to 3 per cent. of U₃O₈; a 5 to 10 per cent. ore is considered high grade; a 20 to 40 per cent. ore is remarkably rich. Uraninite and pitchblende ordinarily contain more uranium than carnotite contains, and even in the impure forms in which they are mined as ores, they often show this greater uranium content. The ordinary uraninite and pitchblende ores carry from 2 to 3 per cent. to 8 or 10 per cent. U₃O₈, and a 20 per cent. ore is very high grade, though some ore runs 60 or 70 per cent.

—Carnotite is an amorphous, soft, powdery material, sometimes more or less coherent and of a talcose or waxy character, generally of a brilliant canary yellow color, though sometimes discolored by iron, organic matter and other substances. It is essentially a hydrous potassium uranium vanadate. Some authorities believe that carnotite is not a distinct mineral, but a mixture of different minerals.

—The terms uraninite and pitchblende are often used synonymously to designate the same mineral, but more properly the term uraninite is a general name for all forms of the mineral and especially for the purer and distinctly crystalline variety, and the term pitchblende is applicable to the impure amorphous form. It is black or grayish black in color, opaque, and often has a submetallic glossy or pitchlike luster. Uraninite is often remarkably lacking in distinctive characteristics, so that its presence might frequently be overlooked. For this reason it seems possible that this mineral, now known in only comparatively small quantities, may some time in the future be found more abundantly.

Uraninite, like carnotite, has a somewhat indefinite formula, but is essentially a combination of the two uranium oxides UO₂ and UO₃, in which UO₂ seems to act as a base and UO₃ as an acid. A number of both the rarer and commoner elements are often associated with them. The relative amounts of the two oxides vary considerably in different specimens, especially in the impure form of pitchblende, and no definite formula can at present be given. In pitchblende a notable amount of water, perhaps sometimes in chemical combination, is often present. Several other minerals much rarer than uraninite or pitchblende are related to them in composition, among them being cleveite, bröggerite and nivenite.

—Though carnotite, uraninite and pitchblende are the most abundant of all the radium and uranium materials in nature, and produce almost all the radium and uranium of commerce, yet many other minerals contain both metals, and though as yet known only in such limited quantities as to be of small commercial value, may in the future be found in quantities of importance. Among them may be mentioned tyuyamunite, a hydrous calcium uranium vanadate often associated with the hydrous potassium uranium vanadate described above as carnotite; autunite, a hydrous calcium uranium phosphate; torbernite or chalcolite, a hydrous copper uranium phosphate.

The only regions of the world that have as yet produced any large amounts of radium and uranium minerals on a commercial scale are Colorado, Utah and Austria. Cornwall, Australia and Germany have produced a small quantity of these minerals. They are known in small quantities in France and Portugal, and have been reported in India and German East Africa, but in these regions they have not yet become commercially important. They occur sparingly, so far as yet known, and practically as only mineralogical curiosities, in Connecticut, North Carolina, Canada, Norway and many other regions, but may in the future be found in larger quantities.

Minute quantities of radium or its products of disintegration occur in almost all rocks and in the atmosphere, and in the waters of the sea and land, but in such small amounts as to be unavailable as a source of these substances. The source of all radium of commerce at the present time is in the certain few uranium minerals already mentioned. They are found in formations of various geologic ages, from recent superficial deposits to the older crystalline rocks, but show a tendency toward certain modes of occurrence, such as in southwestern Colorado and southeastern Utah as an impregnation in sandstone; in eastern Colorado, Cornwall, Austria and South Australia as one of the gangue minerals in veins of other ores; in North Carolina, Canada, Norway and West Australia in pegmatite or other feldspathic dikes.

—The commercially important deposits of ores of radium and uranium in the United States are, so far as yet known, confined to the carnotite regions of southwestern Colorado and southeastern Utah, and the pitchblende deposits of Gilpin County, in eastern Colorado. In Connecticut, North Carolina and elsewhere, uraninite, pitchblende and other uranium minerals have been found; and near Mauch Chunk, in Pennsylvania, small quantities of carnotite have been discovered, but these occurrences are, so far as known, in quantities too small to be of commercial value.

—The carnotite deposits of southwestern Colorado and southeastern Utah are the most important sources of radium and uranium in the world. In Colorado the largest quantities of ore have come from many mines in Montrose County, especially in Paradox Valley, while Mesa, San Miguel, Dolores, Rio Blanco, Routt and other counties have been producers. In southeastern Utah the ores are carnotite, as in southwestern Colorado, and occur especially in Grand, Emery and San Juan counties, but have not been worked to the same extent as in Colorado.

The carnotite of Colorado and Utah occurs as an impregnation in sandstones and shaly sandstones, mostly in the McElmo and the La Plata formations, lying at the top of the Jurassic beds and below the Cretaceous sandstones and conglomerates of the region. The deposits seem to have been formed by the precipitation of carnotite from solution along certain strata of these formations, and the material occurs along bedding planes, in fissures and small cavities, in layers or irregular masses from a fraction of an inch to several inches in width, and sometimes as a general impregnation of the sandstone for several feet in thickness. It seems to be especially abundant in strata impregnated strongly with vegetable or animal matter, and is often in unusual quantities in lignitized or petrified trunks of trees. This phenomenon suggests the influence of organic matter in precipitating and segregating the carnotite.

The rocks carrying the carnotite lie horizontally or dip at low angles in most parts of the Colorado region; in Utah they lie often in the same way, but occasionally dip at steep angles. Where they appear on the surface, the carnotite sometimes impregnates certain strata for several hundred feet or more along the outcrops, but more generally it occurs in spots along them, with little or no carnotite in the intervening spaces. As these outcrops are followed into the hillsides, the ore appears to be even more irregular in its distribution than on the surface, and in many or most cases it becomes much scarcer the further it is explored underground, until within 10 to 40 or 50 feet from the surface it often mostly or entirely disappears. There are exceptions to this feature, but the gradual and often rapid decrease in quantity and grade of the carnotite ore as it is followed into a hill is generally recognized. This fact suggests that the carnotite may have been redissolved in the sandstone and carried to the surface by capillary action in this arid climate, forming rich, superficial efflorescences.

In many of the carnotite deposits, vanadium minerals occur independently of the vanadium in the carnotite, but this association is not always observed. They occur in sandstone and often give it a dark-gray or blackish color.

In eastern Colorado several mines near Central City, Gilpin County, have produced limited quantities of pitchblende. Among these are the Kirk, the Wood, the Belcher, the Alps, the German and the Calhoun mines. The pitchblende occurs as a subordinate constituent in the gold-bearing veins of that country. The veins intersect old metamorphic rocks intruded by igneous rocks. The mines of Gilpin County are today producing little if any pitchblende, and the total production has been small, amounting in all probably to only a few tons. Much more pitchblende, however, was let go to waste in former days when the mines were worked for other ores and the value of uranium was not recognized.

—The United States is today by far the largest producer of radium and uranium ores in the world, and is also the largest producer of manufactured radium and uranium compounds. Before the war, England, France and Germany, especially Germany, imported large quantities of American ores and extracted the radium in a refined state as its different salts, much of which was returned to the United States for sale. Now, however, American ores are almost entirely treated in the United States, with the exception of a little shipped to England and possibly to France. The Standard Chemical Co., of Pittsburgh, was a pioneer in this work, and others quickly followed, among them the National Radium Institute, of Denver; the Schlesinger Radium Co., of Denver; the Chemical Products Co., of Denver; the Cummings Chemical Co., of Lansdowne, Pa.; the Radium Luminous Materials Corporation, of New York, and others.

Before the discovery of radium in 1898, but little attention was given to uranium ores in America, though some little pitchblende was shipped from the Central City, Colorado, region for use in making uranium compounds. Shortly after the discovery of radium, however, mining was begun on the carnotite of southwestern Colorado, and from 1900 to 1910 several companies were formed to work these ores both in Colorado and Utah. The pitchblende of Central City also began to attract renewed attention. For a few years active work was done in prospecting for it, but the quantities have so far proved to be small. A few tons probably represent the total amount derived from these mines since the search began. In the meantime, however, the production of carnotite increased rapidly until 1915, when it greatly decreased on account of the curtailment of shipments to Europe. In the latter part of 1916, however, the production increased again, on account of the increased consumption of ore in this country, and in 1918 the production was very active, largely on account of the increased use of radium not only in medicine but especially in luminous paints.

The amount of radium and uranium ores produced in the United States, or in fact anywhere, during a given period, is difficult to determine, on account of the different bases on which reports are made, but it may be said that the tonnage is small compared with that of ores of commoner metals, a few thousand tons being a large amount of carnotite, and simply a few tons or pounds being a large amount of pitchblende. Though the mining of radium and uranium ores in the United States began about 1900 or shortly before, no very large quantities were produced until 1912, when about 1,100 tons were mined, consisting chiefly of Colorado carnotite. The production gradually increased to several thousand tons yearly, practically all of which is carnotite from Colorado and Utah.

—The most important radium and uranium ore in Europe at present is the uraninite or pitchblende found in the mines of Joachimsthal, in Bohemia. It occurs as a subordinate gangue mineral in certain silver veins of that region which intersect metamorphic and igneous rocks, and has been actively worked ever since the discovery of radium by M. and Mme. Curie in 1898. Before that time the mineral had a certain value as a source of uranium compounds.

These Austrian mines are second to those of the United States as a source of radium and uranium, but their production equals only a very small part of that of this country. Until the Great War this production was controlled largely, if not wholly, by the Austrian government, and as the production is said still to continue, it is probably still controlled in the same way.

—Next in importance in Europe to the uraninite or pitchblende ore of Joachimsthal as a source of radium and uranium, is the similar ore in some of the mines of Cornwall, England. It occurs as a subordinate mineral in the gangue of some of the old tin and copper mines, in veins intersecting metamorphic and igneous rocks, especially at St. Just, St. Ives, Grampound Road, St. Austell and elsewhere. The production and treatment of the ore has been under private or corporate auspices and the amount produced has not been large.

—In Germany the production of radium and uranium ores has always been insignificant. A small quantity of such ores has been produced at Schneeberg, Johanngeorgenstadt, Annaberg and elsewhere. Before the war, Germany was a large producer of manufactured radium and uranium compounds, but they were derived mostly from imported American ores.

—With the exception of Joachimsthal and Cornwall, Europe has produced but small quantities of radium and uranium minerals. A little uraninite or pitchblende has been found in other localities in Austria, such as Przibram and elsewhere, and sparingly in Norway. Autunite and other uranium minerals have been found in small quantities near Autun, France, and near Sabugal and Guarda, in Portugal, but no important quantities have been produced.

—In South Australia carnotite, autunite, torbernite and other rare uranium minerals occur in regions of metamorphic and igneous rocks at Radium Hill, near Olary, and at Mount Painter, in the Flinders range. A few hundred tons of ore containing these minerals have been mined by private or corporation interests. Most of this has been sent to Woolwich, near Sydney, New South Wales, or to England, for the extraction of the radium. Since the war started no very active mining operations in such ores have been carried on in the South Australian region.

At Cooglegong, in Western Australia, the uranium mineral fergusonite and to a less extent the uranium mineral euxenite occur in the surface detrital material of the region. At Wodgina the minerals mackintoshite, thorogummite and pilbarite, all hydrous silicates of uranium, thorium and lead, occur in an albite pegmatite dike. No important quantities of these Western Australia ores have yet been produced.

—Radium and uranium minerals have been reported in India and German East Africa, but no important quantities have yet been produced.

The prospect for increased discoveries of radium and uranium minerals at the present time seems best in the carnotite regions of Colorado and Utah. The workable deposits seem to be more or less superficial, and perhaps no large quantity of ore may be found in any one spot, yet the great extent of the region in which the formations carrying carnotite occur, will supply an immense aggregate amount of ore.

Increased discoveries of uraninite, pitchblende and other uranium minerals in Europe seem possible, even though that continent has already been well explored for them. Moreover, new discoveries of different radium and uranium minerals may very likely be made in still other parts of the United States than those mentioned, and in less explored parts of the world, especially certain regions of South America, Australia, Asia and Africa. Many of these minerals, especially pitchblende, have no very distinctive features when first observed, and might readily be overlooked many times before their true nature was discovered. Hence the possibilities of future discoveries.

CHAPTER XII ZIRCONIUM By H. C. Morris — USES OF ZIRCONIUM — GEOLOGICAL AND GEOGRAPHICAL DISTRIBUTION — The Natural Oxide. — The Silicate. — POLITICAL CONTROL — Brazil. — India. — United States. — General. — SUMMARY

As early as 1830 an attempt was made to use zirconia buttons, heated to incandescence, for lighting the streets of Paris. In 1885 an incandescent gas mantle of zirconium oxide was patented, but was replaced in a few years by thorium. About 1900 zirconia was used in the Nernst glower, and it has also been used in place of lime and magnesia as the incandescing material in the Drummond light. It is also said to be used in the Bleriot light, and its use in flares has been suggested.

During the past few years Dr. C. M. Johnson has succeeded in manufacturing laboratory ware made from zirconium minerals mixed with other refractories. Filtering crucibles, muffles, combustion tubes and boats, pyrometer protection tubes, and Kipp generators are now on the market, competing in price with German porcelain and fused silica. Zirconia crucibles are made from the fused material ground in a suitable mill. The powder is pressed or molded into shape with an organic binder, such as starch, or perhaps, better still, with a plastic cement made by grinding the fused material to 20 mesh, when it becomes colloidal in the presence of water. After drying, the articles are burned at a very high temperature (2300 to 2400°C.) until contraction ceases.

Fused zirconia has a high thermal endurance; is not affected when heated to redness and plunged into cold water, its coefficient of expansion being as low as 0.00000084; and its resistance to crushing is many times that of quartz glass. Its hardness is between that of corundum and quartz; its specific gravity 5.89, and porosity below 1 per cent. Its melting point is 2950°C, but 0.5 per cent. impurity reduces that by 100°C. Platinum, with a melting point of about 1750°C., can be melted to a mobile liquid in zirconia crucibles, and it is claimed that the boiling point of pure iron has been determined in similar crucibles.

Chemically, zirconia is very inert, being highly resistant to acids, fused alkalies, fused quartz, or molten glass. Possibly no other material known to chemists possesses such a combination of desirable refractory properties. Its one undesirable characteristic is its tendency under certain conditions at high temperatures, in the presence of nitrogen or carbon, to become converted into nitride or carbide.

An instructive paper entitled “Zirconia as a Refractory,” by E. H. Rodd, was published in the Journal of the Society of Chemical Industry, June 15, 1918.

Zirconium oxide as an opacifier has been thoroughly investigated by Hartman[95] and by Grunwald[96] with promising results; and a number of foreign patents have been granted on the use of the oxide in white ceramic enamels. Zirconia seems to be especially suitable for the manufacture of refractory bricks, or it can be applied as a lining or surfacing to other less desirable refractories. Continental practice along this line is said to have been much more highly developed than practice in this country, one example quoted being actual practice tests of a Martin Siemens furnace with a zirconia-lined hearth. After four months of continuous operation at high temperatures the hearth was still in good condition and gave promise of lasting at least an equal length of time without renewal. Statistics compiled from these tests showed a saving of about 50 per cent. in actual maintenance costs in favor of zirconia over the other refractories ordinarily used for such purposes. Bradford[97] quoted Podszus[98] as claiming to have made a furnace with the pure oxide which had first been fused in an arc furnace and then ground; and in which temperatures of 2400° to 2500°C. were obtained by firing with gas and oxygen.

The most important question regarding zirconium at the present time has to do with the remarkable properties that some of its advocates claim it imparts to steel. That the Germans have had this use in mind for some time is evidenced by the numerous patents they have obtained covering the use of zirconium and its alloys.

Zirconium has been obtained in the amorphous and the graphitic state; and Wedekind has produced a metal of 99.8 per cent. purity resembling white cast iron in appearance, with a hardness of 7.8 (Mohs); specific gravity 6.40; specific heat, 0.0804; heat of combination, 1958 calories; and melting point, 1530°C.

Numerous alloys of zirconium have been made and a number of foreign and domestic patents have been issued covering various alloys, both ferrous and non-ferrous. It is stated that ferrozirconium is finding a limited application in the steel industry as a scavenger for removing nitrogen and oxides. An English patent, No. 29,376, covers the use of zirconium as a scavenger, the alloy containing 20 per cent. of the element and being used in an amount equal to about 1 per cent. of the weight of steel treated.

Another alloy containing 40 to 90 per cent. zirconium, the rest being mainly iron, is said to be free from metalloids and oxides, and malleable and ductile. Alloys covered by United States Patent No. 1,151,160 are claimed to be highly resistant to oxidation and chemical reagents. They have a metallic lustre and take a high polish, are readily malleable and ductile, and it is suggested that they may find an important application in filaments for electric lamps, as they are said to have the property of selective radiation. A typical analysis of some of the alloys claimed to have been produced under this patent shows Zr. 0.65 per cent., Fe 26 per cent., Ti 0.12 per cent. and Al 7.7 per cent.

A widely circulated statement to the effect that zirconium has been used in Germany in the production of steel for armor plates and armor-piercing projectiles has not been substantiated, so far as the writer knows, by any records of analyses.

The use of zirconium for alloying in steel is so new that, pending definite determination by disinterested competent authorities of the exact properties, if any, which zirconium imparts to steel, judgment as to its value for this purpose should be withheld.

Zirconium carbide has been patented for filaments for incandescent electric lamps and it has also been used as an abrasive. Tried as a pigment, zirconia has been found to have good covering power and should be considered where protection from acids, alkalies, or gases is particularly desired. The basic acetate has been used for weighting silk, and the pure oxide is used as a substitute for bismuth subnitrate in X-ray work.

Zirconium occurs in nature in commercial quantities as a mixed oxide and silicate known as baddeleyite, sometimes called brazilite, and as the silicate, zircon. Baddeleyite, as supplied to the trade, usually carries 80 to 85 per cent. ZrO₂. The silicate, zircon, carries about 65 per cent. ZrO₂. The oxide deposits, containing as they do a higher percentage of zirconium and the ore being more pure and easier to reduce, will in all probability become the principal source of zirconium.

The principal known deposits of zirconium ores are in Brazil, India and the United States, the countries being named in the relative order of their commercial importance.

—The natural oxide, baddeleyite, or brazilite, occurs only in Brazil in commercial quantities and is described in Mineral Foote-Notes by Meyer,[99] who writes as follows:

The oxides have also been found in the State of Montana, and in Ceylon, Sweden, and Italy, but none of these occurrences are of commercial importance.

—The simple silicate, zircon, is found in seashore and river concentrations of monazite sands, associated with ilmenite, garnet, rutile, and various other heavy minerals usually found in such places.

An important concentration of zircon occurs along the coast of Brazil, in the states of Bahia, Espirito Santo, and Rio de Janeiro, where cusps of the beaches are protected on the north by granite headlands and bordered by Tertiary bluffs, which are cut by various streams and lagoons that constantly furnish fresh material for the concentrating action of the tides and waves.

Probably the next most important occurrence of zircon is in India, in the beach sands of the province or state of Travancore at the extreme southwestern end of the Hindustan peninsula.

Next in importance is an occurrence in the United States at Pablo Beach, Florida, where not only the beach sands, but the dunes bordering them, contain appreciable quantities of the following minerals in their relative order of abundance: ilmenite, garnet, epidote, zircon, rutile, and other heavy minerals including monazite.[101]

Other occurrences in this country, most of which are of academic interest only, are in Colorado, at St. Peter’s Dome, near Pike’s Peak; in Idaho, in the Clearwater region and elsewhere in black sands and in certain granitic rocks; in Sussex County, New Jersey, at the Williams mine, where zircon occurs abundantly in magnetite; in New York at Lyon Mountain, Clinton County; at a few places near Crown Point; abundantly in pegmatite at Old Red Mines, Mineville, Essex County, and in numerous places in Orange County on the south, and St Lawrence County on the north. In North Carolina, in Burke, McDowell, and Rutherford counties, zircon occurs in monazite sands, and also in Henderson County near Zirconia and in Fredell County near Sterling.

Large crystals of zircon occur in a small pegmatite area in Comanche County, Oklahoma, in the southwestern portion of the Wichita National Forest. Oregon has many localities in which the presence of zircon has been noted, chiefly in black sands, old and present beaches, placer gravels, etc., and the same is true of Washington. In Virginia, zircon is found in pegmatite in Aurelia County, and in sandstone near Ashland, not far from Richmond.

Zircon is also found in Norway, the Ural Mountains, Ceylon, Australia, and British South Africa.

The important zirconium resources of the world are controlled politically, in the order of their commercial importance, by Brazil, Great Britain, and the United States.

—A number of years ago John Gordon, an American mining engineer, became interested in deposits of monazite sand on the coast of Brazil in the vicinity of Prado, Bahia. A thorough investigation of all the known monazite deposits of the world showed that those in Brazil were by far the most desirable, and that those in Travancore, India, were second in commercial importance.[102]

Other firms exporting zirconium minerals from Brazil, in addition to Gordon & Rogers, of 141 Broadway, New York, are Suffern & Co., of 135 Broadway, New York; S. R. Scott & Co., 39 Broadway, New York; Foote & Co., Philadelphia, Pa.; P. S. Nicholson & Co., Caixa 91, Rio de Janeiro; E. J. Lavino & Co., Bullitt Building, Philadelphia, Pa.; Luiz de Rezende & Co., Rua Ouidor, Rio de Janeiro, Brazil; and Chas. Spitz, also of Rio de Janeiro, who is agent for the Société Minière, a French company in which Rezende & Co. are said to have a considerable interest. Sometime ago the firm of A. C. de Freitas & Co. of Hamburg, Germany, had a contract from the Brazilian government on monazite sands and agreed to export at least 1,200 tons annually. How much zircon that company exported is not known. The de Freitas properties are now being worked by the Société Minière (French).[103]

Until very recently, zirconium has been of minor interest in this country, the monazite sands having been exploited for their thorium contents only, not for zirconium. However, Germany and Austria seem to have placed considerable value upon zirconium-bearing sands, and, as shown by the attached table, more was produced in 1913 than in all the time prior, and practically all the material produced during that year went to Germany. This is in accord with the efforts of Germany, just before the war, to obtain tungsten and molybdenum, and is an evidence of preparations long before hostilities began.

—Before the war, the German users of monazite were in control of the Travancore, India, deposits. That control of course ceased and the contracts were cancelled. The India Office decided that, in the future, all directors of the company must be British born, and that the company must be ready at all times to sell monazite sand to British firms, direct, at a fair price.

—It is hardly probable that the deposits in the United States will be able to compete, on a commercial basis, with the Brazilian ores; but, if the necessity should arise, this country can produce, within its own borders, enough zirconium to manufacture many thousand tons of zirconium steel. The cordial commercial relations between the United States and Brazil will probably protect this country from any undue restraint on exports from South America.

—All of the large countries interested have facilities for making the ferro-alloy. Numerous alloys of zirconium have been made, and a number of patents, both foreign and domestic, have been issued covering various alloys, both ferrous and non-ferrous. No secret processes, as such, are known to the writer.

Table 34.—Production of Zirconium Minerals in the United States and Brazil, 1902-1916[104]

The principal use for zirconium ores at present is determined by the refractory properties of the oxide, zirconia. Refractory bricks and shapes for furnace linings, chemical ware, and other heat, acid, and alkali resisting articles are made of zirconia, and are finding a limited market.

The recent interest in zirconium is due to the remarkable properties which it is said to impart to steel. Its real worth, or function, in that direction is yet to be definitely determined, and tests conducted by the Bureau of Mines, Bureau of Standards and others are being made to ascertain the facts.

The best and most available source of supply at present is Brazil, where the natural oxide, baddeleyite, occurs in considerable quantities in the states of Minas Geraes and Sao Paulo. The deposits have not been explored sufficiently to make any reliable estimate of tonnage possible, but, judged from their surface showing, they are of vast extent. The silicate, zircon, is found in Brazil, India and in the United States in commercial quantities.

The important deposits of zirconium minerals are controlled by Brazil, Great Britain and the United States, but the actual ownership of many of the deposits is unknown. This is particularly true of the oxide ores.

CHAPTER XIII MONAZITE, THORIUM, AND MESOTHORIUM By R. B. Moore — USES OF MONAZITE — GEOLOGICAL AND GEOGRAPHICAL DISTRIBUTION — United States. — Brazil. — India. — CHANGES IN TREATMENT PRACTICE — POLITICAL CONTROL — COMMERCIAL CONTROL — United States. — Brazil. — India. — POSITION OF THE UNITED STATES

Practically the only use of monazite has been as a source of thorium salts. In extracting these, by-products are recovered, such as cerium, lanthanum, and other rare earths. Thorium salts are used almost exclusively for the manufacture of Welsbach mantles, which consist of 99 per cent. thorium oxide and 1 per cent. cerium oxide. For this use there is no known substitute. The one other use of thorium salts is in ordinary chemical laboratories, but this use is very limited. The fluoride and other salts of cerium are used in connection with the flaming arc, their presence giving increased luminosity.

Mesothorium is a radio-active element always found in thorium minerals. Until quite recently it has been thrown away in the manufacture of thorium nitrate; but it is now being produced as a by-product, and is useful as a substitute for radium in luminous paints, and for therapeutic purposes.

The principal sources of monazite are Brazil and India, although it has been mined successfully in the United States in the Carolinas and in Idaho. It has been found in Swaziland, Africa, and in Australia, and also, to a limited extent, in native rock and in placers in Ekaterinburg, Russia.

Monazite is usually found in the gravels of small streams or bottom lands, although it is sometimes found in the soil of hillsides. In Brazil and India it occurs mainly in the beach sands of the sea coast. In places it is found in small crystals in gneiss, granite and pegmatite rocks. As these rocks become disintegrated, the crystals are washed into streams and with other heavy sands are deposited in the stream beds. On the coast of Brazil, the monazite grains from the crystalline rocks of the coastal mountains are concentrated by the waves of the sea.

—The deposits of the Carolinas cover an area of several hundred square miles east of the Blue Ridge Mountains. In North Carolina, the counties of Cleveland, Burke, Alexander, Rutherford and Lincoln furnish the richest deposits. In South Carolina the only deposits of value are in the counties of Cherokee and Greenville. Practically all of the monazite mined in the Carolinas is derived from gravels in streams and bottom lands, the miners usually following the stream courses. The gravels vary greatly in thickness, and it is therefore difficult to make a true estimate of the average, but in general the monazite-bearing gravels are between 1¹⁄₂ and 2¹⁄₂ feet thick. The top soil in the bottom lands averages 3 to 6 feet thick and may be 7 feet or more.

The deposits in the State of Idaho are near Centerville and Idaho City. In the future, under more favorable conditions of price, transportation, etc., these deposits may possibly become a commercial source of monazite. Almost all of them contain small quantities of gold. The gravel beds are considerably thicker than those in the Carolinas, and with the gold content might be more profitable were it not for labor being higher priced.

Monazite has been found in Colorado, in the Newland Gulch district, 20 miles south of Denver, where it occurs in gravels that carry considerable gold.

—There are three kinds of monazite sand deposits in Brazil; the deposits within the government lands along the coast; deposits lying behind the government coastal lands, which are private state possessions or belong to private parties; and inland deposits. The bulk of the monazite is derived from coast sands in the states of Espirito Santo and Bahia, the sand being washed by means of oscillating tables or sluice boxes. The coast lands are the property of the federal government for 33 meters inland, measuring from the point where the sea waves wash the beach at mean high tide. This uncertain method of marking property has of course given rise to disputes when boundaries are established.

At a few places along the coast strips of monazite-bearing sands lie directly behind the government land, and some of these might be worked profitably were it not for the fact that it has been difficult to prove to the federal government that these sands were not taken from the nearby government land. One French concern has exploited such lands in the State of Rio de Janeiro. Along the banks of the large rivers, such as Parahyba, there are great quantities of black sands with traces of monazite. Near Sapucaia such deposits have been worked by a French concern. Many of the inland deposits can not be exploited on account of the expense of transportation of the products, as the deposits are many miles from a railroad.

—India is the newest source of monazite sands, the deposits lying on the sea beach like those in Brazil. The deposits are in the Travancore district near the southwestern end of the Hindustan peninsula. Very little information is available concerning these deposits.

The general method of treatment employed until quite recently has involved leaching the concentrate with concentrated sulphuric acid, thus getting the thorium, cerium, and other rare earths in solution and separating them from the silica, zircon, ilmenite and other insoluble products. From this stage different companies used slight variations in practice, such variations being kept strictly secret, although they all involved the precipitation of the thorium as oxalate by means of oxalic acid.

At the outbreak of the war the price of sulphuric acid went to four or five times the original cost, and the increased price of oxalic acid was practically prohibitive. Consequently the manufacturing companies had to change their entire procedure and to use chemicals that they could obtain at a reasonable price. In this difficult undertaking the companies were successful, and at least one company devised a process that was considerably more efficient than the old one.

At present mesothorium is being produced as a by-product by the Lindsay Light Co. and the Welsbach Co., the process used by the latter company having been originated by the Colorado Station of the United States Bureau of Mines. This process is cheap and extremely efficient, and will no doubt enable the Welsbach Co. to compete commercially with any other manufacturer of mesothorium. Of course as the process was developed by the Bureau of Mines it will ultimately be made available for anyone, but as mesothorium can only be made at a profit as a by-product of thorium nitrate, anyone who manufacturers mesothorium must first establish a thorium industry.

The important monazite resources of the world are controlled politically by three nations: the United States, Great Britain (India) and Brazil. The deposits of the United States, in normal times, probably can not be worked successfully in competition with the foreign deposits without the protection of a high tariff.

—The widely scattered monazite deposits of the United States are of importance only during a period of abnormally high prices or during the restriction of imports from Brazil and India. The known reserves are small and the deposits will probably never be an important factor in the world monazite market. As far as the writer knows, all of the American deposits are controlled by American capital.

The manufacture of thorium nitrate in this country is closely controlled by two large companies, the Welsbach Co. and the Lindsay Light Co.; they own the only two commercial plants of any size in the United States.

All of the manufacturers of mantles in the United States, with one exception, must obtain their thorium nitrate from one of these two companies. As these companies supply practically all the thorium nitrate requirements of England and France, they control the thorium industry. The only other manufacturer of thorium nitrate in this country is the Block Co., of Chicago, which uses about 15 tons of monazite a year, making sufficient thorium nitrate for its own production of mantles. The Welsbach Co. uses about 1,200 tons of monazite annually and the Lindsay Light Co. about half that amount. The Welsbach Co. has contracts for the delivery of monazite, up to its requirements, from Brazil; the Lindsay Light Co. has obtained all of its monazite from India.

Most of the processes used, including those used by the Welsbach Co. and the Lindsay Light Co., are secret. As thorium can be extracted from monazite in more ways than one, a secret process does not necessarily mean commercial control unless such a process is in every way efficient and the company owning it is willing to get into a commercial war.

—As the Brazilian deposits have for so many years been the chief source of the supply of monazite, the history of their commercial control is practically a history of the commercial control of the monazite industry. About 27 years ago, John Gordon, an American now residing in New York, found monazite on the coast of Brazil. He brought large quantities to Hamburg, Germany, and was able to obtain a monoply of the monazite sand.

At that time the manufacture of thorium nitrate, the principal product of the monazite sand, was confined in Europe to a few large chemical firms in Germany and the Welsbach Co. in Vienna. They not only supplied the European market with thorium nitrate, but also sent large quantities to the United States. The American Welsbach Co. early manufactured thorium nitrates from sands mined in the Carolinas, a protective duty of 6 per cent. making this possible.

In 1902 Mr. Gordon agreed to supply the four large German manufacturers and the Austrian manufacturers with monazite at a price of $150 a ton and a profit on the manufactured nitrates. A close combination thus formed, known as the German Thorium Convention, prevented other thorium manufacturers from acquiring any of the mineral mined by Mr. Gordon, and raised the price of thorium nitrate 100 per cent.

For a considerable period Mr. Gordon exported the sand from the coast lands of Bahia, near Prado, Brazil, without interference. Finally the Brazilian government became acquainted with the value of the resources and decided that no private individual or state government had the right to mine, sell, lease, or remove any monazite on so-called state lands without the consent of the federal authorities. In 1908 the government advertised that coast lands in the State of Espirito Santo would be leased to the highest bidder for the exploitation of the sands. A contract was thus obtained for the firm of A. C. de Freitas & Co., of Hamburg, Germany. By the contract the firm agreed to pay to the Brazilian government a rental equal to 50 per cent. of the selling price of the monazite sands and to export at least 1,200 tons annually.

To avoid trouble the German Thorium Convention arranged later that half of its supply should be furnished by Mr. Gordon and half by the de Freitas company. A new convention was formed by the four German chemical manufacturers with Mr. Gordon and the de Freitas company, preventing firms in other countries that had started to manufacture thorium nitrate from getting raw material. Consequently great efforts were made to find and develop new deposits of monazite. The high price for thorium nitrate made possible the mining of monazite in the Carolinas and its export to Germany, especially to one German manufacturer who was not in the German Thorium Convention.

Ultimately there was an overproduction of thorium and in 1906 the price dropped 50 per cent. Monazite mining declined in all localities where the cost of mining was high, and production in the Carolinas and the interior of Brazil practically stopped.

During the four or five years antedating the war the German Incandescent Gas Light Co., of Berlin, succeeded in controlling the largest manufacturers of thorium nitrate in Europe, except those in France. It controlled both the English and Australian companies and became the active competitor of the so-called Thorium Convention, which at that time had lost much of its power. Mr. Gordon still has extensive interests in Brazil, but he does not have a monoply. The exportation rights from Brazil are in the hands of Luis de Rezende & Co. (Rio de Janiero), Mr. Gordon, and others. Luis de Rezende & Co. is mainly a French concern, but has Brazilian and Portuguese stockholders. The company controls the French company, Société Minière, associated with the Welsbach Co.

As noted above, one French company has exploited monazite deposits in the territory immediately behind the government lands in the State of Rio de Janeiro. Another French company has worked the black sands along the Parahyba River, near Sapucaica, which contain traces of monazite.

—Before the war, the German manufacturers of thorium nitrate exercised as close control over the monazite deposits of Travancore, India, as over those of Brazil. Only a limited quantity of the sand was sold to gas-mantle manufacturers and other consumers in the United Kingdom, and then at a price nine times the price paid by the German consumers. Such a monoply of the supplies of raw material made the German monoply of the thorium nitrate industry almost complete.

According to S. J. Johnstone, in an address at the annual meeting of the Society of Chemical Industry in July, 1916, the Germans obtained practical control of the Travancore monazite deposits in the following manner: A lease for working these deposits was granted some years ago by the Travancore Durbar, with the approval of the Government of India, to the London Cosmopolitan Tin Mining Co., which contracted to sell the whole of its output to a German firm. Soon after the outbreak of war it was found that the whole of the preference shares and 11,000 of the ordinary shares of the Travancore Minerals Co. were held in trust for the Auer company, of Berlin.

The India Office decided that in the future all directors of the company working the concession must be British-born and that the company, must be ready at all times to sell monazite sand direct, and at a fair price, to British firms. German contracts were canceled. A second company, Thorium, Ltd., obtained a 20-year lease to work 150 acres in Travancore for monazite sand, and is exporting the sand and manufacturing thorium nitrate from it at works in England. A great deal of Travancore monazite has been imported by American companies.

As outlined above, it can be readily seen that the United States is dependent upon Brazil and India for its raw materials, as domestic deposits are not large enough to furnish the required supply and cannot be worked in competition with the more cheaply mined foreign deposits.

The average concentrate obtained in the Carolinas runs about 3¹⁄₂ to 4 per cent. thorium oxide; that obtained in Brazil averages somewhat over 8 per cent. Under such conditions it is difficult for the Carolina monazite to compete with that from Brazil or from India. In addition, a very considerable amount of the Carolina monazite available has been removed. The old workings are more or less covered up and the whole industry has become completely disorganized.

Whilst these deposits were being mined and operated farmers were in the habit of making their own concentrate in crude sluice boxes. The product thus obtained averaged about 35 per cent. monazite. The concentrates were then sold to a refinery, where it was best treated by electromagnetic separators, such as the Wetherill machine. The final product obtained from these machines was ready for chemical treatment for the extraction of the thorium.

Practically the same treatment is given to the monazite from Brazil and India. As the concentrate obtained is of much higher grade, the additional charges for freight and duty, which are not borne by the Carolinas product, are more than offset. Undoubtedly, unless a very high tariff is placed on the monazite from Brazil and India, our future supplies will come from these two sources, at least for some time. It is very doubtful whether with a high tariff the Carolina deposits could furnish the monazite required in this country, even for a few years, and under the most favorable conditions it would take some time, possibly six months to a year, to revive the industry.

The Allies and practically the whole world are dependent upon the United States for the manufactured products, thorium nitrate and gas mantles. Whether this monoply will continue is doubtful, as there is a movement in England to encourage both the thorium nitrate and the gas-mantle industry.

CHAPTER XIV COPPER By F. W. Paine — INTRODUCTION — NORTH AMERICA — UNITED STATES — Reserves of United States Copper Mines. — CANADA — CUBA AND THE CARIBBEAN — MEXICO — SOUTH AMERICA — AFRICA — AUSTRALASIA — ASIA — EUROPE — SUMMARY

One country stands pre-eminent as the world’s great producer of copper, and that is the United States, whose production was 60 per cent. of the total world output in 1917. Iron, coal, oil and copper are fundamental raw materials of which the United States produces more than any other country, but only in copper and in oil is the output greater than that of all other countries together. In copper this has been true since the early nineties. American copper, English gold, Russian platinum and Chilean nitrate are common phrases in world markets; as common as the commodities themselves.

No other country produces or has for many years ever produced one-sixth as much copper as the United States. While the world output of copper has been increasing, at the average rate of 5 per cent. annually for 10 years up to 1914 and three times as rapidly since then, the relative importance of the United States has not declined. On the contrary it has increased at a greater rate than the total world output. Certain individual countries, it is true, have since 1914 increased their output faster than the United States, but there is no indication that the United States will lose its present dominating leadership.

Because of the magnitude of the copper industry of the United States, great refining plants have been built up here. American capital also has gone largely into Canadian, Mexican and South American copper properties. As a result the United States now imports nearly one-third as much copper as is produced (18 per cent. of the total world output in 1917). Thus American capital controls, through refining in addition to ownership of mines, 78 per cent. of the world’s copper production. This control should also be equally strong as regards selling. Obviously, a large part of our domestic, and, as regards statistics, all the imported copper, is exported in finished form—copper ingots and bars, brass, electrical machinery, etc. But as regards selling and even mine ownership in Mexico and South America, there is considerable German control; although the important mines of Canada, Mexico and South America are owned by either American, British or French interests, except those owned by local foreign capital.
