What is antimony? Antimony is a silverywhite metal that is found in the earth’s crust In the environment, antimony metal is found combined with other substances to form antimony compounds that can be found in ores (rocks found in nature with minerals in them) Antimony can exist in two chemical “states” called trivalent or pentavalentBy the 18th century, antimony was being roasted to reduce it to metal In this process, stibnite was calcined to form an oxide, then reacted with carbon to liberate metal antimony, as follows: 2Sb 2 S 3 total antimony ore mining control target of 90180 t (metal) The total control index for antimony ore for every province (region) was 65180Beneficiation of Antimony Oxide Ore: A Review Springer
