Stibnite Ore Concentrating

How Antimony is Processed by Flotation

The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore.The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of quartz but contains, in addition, a small amount of talc.

Reductive leaching of stibnite (Sb2S3) flotation

The reductive decomposition of a stibnite (Sb 2 S 3) flotation concentrate using elemental iron was investigated in hydrochloric acid.The leaching process which proceeded via both reductive and non-oxidative chemical decomposition reactions achieved desulphurisation in excess of 95% to produce elemental and dissolved antimony species, ferrous ions and hydrogen sulphide gas.

Arsenic and Antimony Sulphide Minerals in Cyanidation

The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment, realgar, and stibnite is usually difficult or even impossible. Extractions are low and the solutions soon become ‘foul.’ The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected.

Stibnite Wikipedia

Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.

Antimony tends to concentrate in sulfide ores along with copper, lead and silver. It occurs sparingly as a free element, but when it does it is usually in association with arsenic, bismuth or silver. The principal ore minerals of antimony are stibnite and jamesonite, but it can also be a byproduct of certain other minerals. Eighty percent of
