摘　　要：采用氯化浸出处理铅锑冶炼过程产生的冰铜渣,分离回收渣铜、锑、铅、银等有价金属。通过单因素和正交试验,得到浸出最佳参数为:H_(2)SO_(4)浓度2.0 mol/L,HCl浓度2.0 mol/L,浸出温度90℃,浸出时间120 min,在此条件下铜和锑主要进入溶液,浸出率分别99.52%,99.36%,铅、银主要进到浸出渣,浸出率仅为4.21%,1.54%,分离效果良好。试验可为从冰铜渣中有价金属的回收提供科学参考。The matte slag produced in lead-antimony smelting process was treated by chlorination leaching,and copper,antimony,lead,silver and other valuable metals were separated and recovered from the slag.Through single factor and orthogonal test,the optimal leaching parameters were obtained as follows:the concentration of H_(2)SO_(4)is 2.0 mol/L,the concentration of HCl is 2.0 mol/L,the leaching temperature is 90℃,and the leaching time is 120 min.Under these conditions,copper and antimony are mainly entered into the solution,and the leaching rates are 99.52%and 99.36%,respectively.The leaching rates of lead and silver are only 4.21%and 1.54%,and the separation effect is good.The experiment can provide scientific reference for the recovery of valuable metals from matte slag.
