Simultaneous Removal of S and As from a Refractory Gold

2019-4-29  S and As are common impurities in refractory gold ores and must be removed before gold extraction. Thermodynamic analyses show that it is possible to simultaneously remove S and As by an O 2-enriched single-stage roasting, which is confirmed with experimental results from roasting of a gold refractory ore.The range of optimal O 2 requirement is narrow and varies
