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.
