一、前言铜镉渣系锌湿法冶金和立德粉生产的中间产物,含有多种金属,是一种很有价值的资源。国内有关企业的统计资料表明,铜镉渣的大致成分(%)为:Zn40～50,Cd5～15,Cu7～10,Ge0.01～0.02,Ga0.008～0.015,In0.01～0.1。对于这种渣的全面综合利用,目前尚未引起足够的重视,也无有效的回收措施;有的单位虽在进行回收,也
First, the preface Copper and cadmium slag zinc hydrometallurgy and lithopone production of intermediate products, containing a variety of metals, is a valuable resource. Statistics of relevant domestic enterprises show that the approximate composition (%) of copper-cadmium slag is: Zn40-50, Cd5-15, Cu7-10, Ge0.01-0.02, Ga0.008-0.015, In0.01-0.1. For the comprehensive utilization of this kind of slag, it has not attracted sufficient attention yet and there are no effective measures for recovery. Although some units are carrying out recycling,
