原料固体矿浆在硫化氢存在下与过量盐酸调和。调和的固体在氧化浸出溶液中搅拌,氧化还原电位选择低于550毫伏,以改进铜与金和铂族金属
The raw solid slurry is reconciled with excess hydrochloric acid in the presence of hydrogen sulphide. The blended solid is stirred in an oxidizing leach solution with a redox potential of less than 550 mV to improve copper and gold and platinum group metals
