ANTIMONY PRODUCTION BY CARBOTHERMIC REDUCTION OF

production of pure antimony trioxide and/or metallic antimony. The conventional technology for the production of metallic antimony from stibnite concentrates is primarily by oxidizing roasting to convert the stibnite into volatile antimony oxide (Sb 2 O 3), which is subsequently reduced to antimony metal with carbon [1]. Although this conventional

Antimony Smelting - Mineral Processing & Metallurgy

China now leads the world in antimony production, having contributed during recent years something over 60 per cent, of the world’s production. The history of the antimony industry of China dates back to 1897 when the Tai Shing Co. was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude; and in 1908 the Wah Chang Mining & Smelting Co. was formed for

Polyethylene terephthalate - Wikipedia

Antimony. Antimony (Sb) is a metalloid element that is used as a alyst in the form of compounds such as antimony trioxide (Sb 2 O 3) or antimony triacetate in the production of PET. After manufacturing, a detectable amount of antimony can be found on the surface of the product. This residue can be removed with washing.
