Complete process and equipment solutions for refractory gold
Oxidation is typically carried out at 190–230 °C and at an oxygen partial pressure of 3–7 bar by feeding gaseous oxygen with a purity above 98% into the autoclave. Reactions are highly exothermic, and the temperature in the autoclave is controlled by injecting cooling water into each autoclave compartment separately.CSIRO, Australia, has developed a thiosulfate-based reagent system for gold leaching that has excellent stability and shown broad applicability in the laboratory compared to the thiosulfate system commercially implemented by Barrick to treat double refractory gold ore following pressure oxidation at its Goldstrike Mine in Nevada, USA.ALTA MetBytes What's Happening in Gold Ore
