Objective: To concentrate the sulfide minerals containing gold. Process: The ground ore is mixed with water, reagents, and air. The gold-containing sulfide mineral particles become hydrophobic, attach to air bubbles, and form a froth that is then skimmed off. This process can effectively increase the gold grade and reduce the amount of material ...

Alkaline hot-press oxidation is applicable to the gold-bearing difficult-to-treat ores with high carbonate content. Acidic hot-press oxidation is applicable to the treatment of hard-to-leach gold concentrates containing sulfur and arsenic. Therefore, the acidic hot-pressing oxidation process is more widely used. 4, Joint pretreatment process
