| Abstract | The dependence of the United States on imported high-grade manganese ore and ferromanganese is well known to steel makers and other users of manganese. Normally the high-grade manganese ore produced in this country constitutes less than 2 per cent of the total amount of manganese ore consumed, not including the ore represented by the manganese imported in the form of the alloys ferromanganese and spiegeleisen. During 1916 the domestic production was about three times that of 1915, largely on account of the high prices paid for ore. The exploration for new deposits has also been stimulated, and many discoveries of manganese ore are being reported. Even Avith this outlook for increased production, however, it is not unduly pessimistic to say that the deposits of high-grade manganese ore in the United States will probably never be able to supply the manganese consumed in domestic industries. If, therefore, the importation of high-grade manganese ore were discontinued, numerous industries would be vitally affected. Of these the steel industry consumes by far the largest quantity of manganese. Various ways have been suggested in which this situation may be alleviated in time of need. Some investigators propose the use of substitutes for manganese in steel making. Willcox 1 has recently suggested that aluminum, silicon, and titanium could be successfully used as deoxidizers in steel making to replace a large part of the ferromanganese. Willcox suggests also that by increased importation a reserve of high-grade manganese ore might be accumulated in this country sufficient to keep the steel industry in operation for perhaps a year should imports be stopped. The capital that would be tied up in such a reserve, however, is very large, and other remedies may be considered more feasible. |
