USAC operates the only significant antimony smelter in the United States and it is in a quotsold outquot condition. The Company has proven experience in underground and open pit mining, flotation and gravimetric milling, crushing and screening, dry grinding, cyanide leaching, precious metal refining, pyrometallurgy, and marketing.
The venture between Tajikistan's stateowned aluminium smelter Talco and Chinese company Tibet Huayu Mining Co. Ltd is expected to produce 1.5 tons of gold and 16,000 tons of antimony annually.
Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or sometimes in blast furnaces,

Shortly thereafter, Wah Chang constructed an antimony smelter in Changsha to produce antimony metal using low grade antimony ore. This smelter became one of 24 roasting furnaces and 19 reverberatory furnaces that made up Wah Changes first plant. This plant is viewed as the start of large scale antimony production in China.
Elements that may interfere with the current lead smelting operation include alumina, copper, zinc, tellurium, tin, mercury, arsenic, antimony, and bismuth. Concentrate sources Teck Resources Red Dog Mine in Alaska supplies much of the lead concentrates for the lead smelter. The remainder is purchased from sources in North and South America.
Smelter Ovens in San Emigdio Canyon (29th November 2012) I'm wondering if these old smelters are in any way connected to the early Spanish (or Mexican) mining activities taking place during the mission era. There is evidence for two early mines in this area, one a silver mine and the other an antimony mine.
