摘　　要：采用回转窑硫酸化焙烧的半湿法工艺从铜阳极泥中提取贵金属后产生的尾渣为分银精矿,其中有价金属含量较高,具有很好的开发价值。试验用NaOH碱性熔炼法分离分银精矿,研究较优的工艺条件,并为后续提取浸出液中的Pb、Sn和浸出渣中的Sb、Bi提供了有利条件。By employing the semi⁃wet process of rotary kiln sulphation roasting to extract precious metals from copper anode slime,the tailings produced are silver concentrates,which have a high content of valuable metals and have good development value.The NaOH alkaline smelting method is employed to separate the silver concentrate in the test,and the optimal process conditions are studied,which provides favorable conditions for the subsequent extrac⁃tion of Pb,Sn in the leachate and Sb,Bi in the leaching slag.
