Arsenic and Antimony Sulphide Minerals in Cyanidation

Sep 17, 2014 · 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.

Antimony trisulfide - Wikipedia

Sb2S3 can be prepared from the elements at temperature 500–900 °C: 2 Sb + 3 S → Sb2S3Sb2S3 is precipitated when H2S is passed through an acidified solution of Sb(III). This reaction has been used as a gravimetric method for determining antimony, bubbling H2S through a solution of Sb(III) compound in hot HCl deposits an orange form of Sb2S3 which turns black under the reaction conditions.
