摘要
硬锌是火法炼锌过程中的副产物，含有多种金属元素，采用真空蒸馏的方法综合处理硬锌，使锗铟银富集在蒸馏残渣中，锗的富集倍数为１０倍，直收率大于９６％，铟的富集倍数为４倍，直收率大于９０％．
Hard-zinc is a by product in the pyrometallurgical process of zinc.It containo many other valuable elememts.When hard-zinc is treated by vacuum distillation,germanium,indium and silber are concentrated in the distilled residue.The concentrating ratio of Ge in the residue is 10 times,its direct recovery is more then 96%.The concentrating ratio of In is 4 time,its direct recovery its is more thin 90%.
