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. =South America, Central America and Cuba.=--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.
