Abstract:Calcined cyaniding tailings are solid wastes produced by cyaniding of gold bearing sulfide ore, accounting for more than 50% of total cyanide slag. Gold is wrapped by iron ore and vein stone, which can be recovered effectively only by pyrometallurgical process. Current pyrometallurgical processes include gold and silver recovery by chlorination volatilization roasting, iron recovery by reduction roasting and magnetic separation, and gold and iron recovery by cyanide slag-copper concentrate combined smelting. The cooperative cyanide residue - copper concentrate smelting method has the advantages of high efficiency, economy and environmental protection, and has a broad prospect.
