摘　　要：根据试验结果,提出了一种从含高铜铅氰化金泥中提取Au、Ag、Cu、Pb全湿法工艺。该工艺在硫酸介质中加入一种除铜剂对氰化金泥进行预处理,除铜率达98%;预处理后的含金渣浸金,金浸出率达99.5%以上;用混合还原剂还原出的海绵金,经去杂处理,金的成色达到Au-2标准。A total-wet method to extract Au,Ag,Cu and Pb from cyanidation gold-slime containing high copper and lead is put forward by experiments.The gold slim is pretreated by adding a sort of decoppering agent in the sulfuric acid medium,and the decoppering rate is 98 %.The gold extraction rate from the extracting slag after pretreatment is 99.5 %.Sponge gold is reduced with mixed reducer,and after impurity removement,the gold purity meets the Au-2 standard.
