high gold recovery and the potential for a slight capital cost (CAPEX) advantage over alternative methods of treating refractory gold ore. "The roasting oxidant can be air or pure oxygen, so there may no need for a dedied oxygen plant, which will lower the overall CAPEX," explains Dr Fleming. "If air is used, the SO 2 that is generated is generally too dilute to make acid, so it is ...
