—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.
