回收粗粒金最简单的方法是重力选矿,所用的设备有淘金盘、跳汰机、溜槽、摇床等。浮选法适于处理细粒金矿石。对于成分复杂的矿石,浮选法可以得到很好的分选和富集效果。选得的金精矿根据其成分特点用不同的冶金方法提金。铜金精矿、铅金精矿分别送铜、铅冶炼,随后从铜、铅阳极泥中提取金、银;金硫精矿则可直接用氰化法或焙烧一氰化提金。
Recovery of coarse gold is the most simple gravity separation, the equipment used by pan, jig, chute, shaker. Flotation process for the treatment of fine grained gold ores. For the ore with complex composition, the flotation method can get a good effect of separation and enrichment. The gold concentrate selected according to its composition characteristics with different methods of gold metallurgy. Gold copper concentrate, lead concentrate of gold were sent to copper, lead smelting, then from copper, lead anode slime extraction of gold and silver; gold sulfur concentrate can be directly by cyanidation or roasting cyanide leaching.
