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.
