提高黄狮涝金矿金、银浸出率的试验研究

Experimental study on improving gold and silver recoveries of Huangshilao Gold Mine

根据黄狮涝金矿深部氧化金矿石的特性，对采用过氧化钙强化氰化浸出工艺进行了试验研究。试验结果表明，金的浸出率可达89．37％～92．41％；在浸出过程中加入活性炭，金的浸出率可达95．19％～98．73％，银的浸出率可达42．94％～48．12％。

Experimental study on the process cyanidation adding CaO2 was carried based on the characteristics of gold oxide ore of Huangshilao Goht Mine. The resuhs showed that gold recoveries could be 89.37% ～ 92.41% ,gold recoveries could be 95.19% ～ 98.73% and silver recoveries could be 42.94% ～48.12% when activated carbon was added in cyanide leaching intensified with CaO2.
