Influence of sulfur on the mobility of arsenic and

The biogeochemical cycling of arsenic (As) and antimony (Sb) is coupled with sulfur (S). Biogenic sulfide from microbial sulfate reduction under anaerobic conditions may enhance the release of coexisting As and Sb through the formation of labile thioarsenate (As V-S) and thioantimonate (Sb V-S).To understand the competition between As and Sb for thiolation and

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. However, some
