Arsenic andAntimonySulphide Minerals in Cyanidation

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