摘要
钴是湿法炼锌过程最有害的杂质,不易除去,易复溶。本文通过对逆锑净化的原理及钴复溶原因的分析,提出了用Pb-Zn合金锌粉代替普通锌粉除钴的新途径。
Cobalt is a harmful element in zinc electrolysis, which is removed hardly but re-dissolved easily. This paper analyses the principle of reversing antimony purification and cobalt re- dissolution, puts forward the new way to remove cobalt using Pb - Zn alloy powder without zinc powder.
