摘　　要：湿法炼锌试剂净化除钴工艺采用有机试剂进行除钴,生产中存在除钴效果差、有机分解物在湿法炼锌系统富集、锌电积烧板及熔铸化料困难等问题。本文针对上述问题进行了分析,提出了优化除钴工艺、新液质量、除锗工艺参数以及去除纳米硫化锌的思路。通过实施优化措施,有机试剂的使用量显著减少,有机物在系统中的富集也显著降低,净化新液中钴、镉等杂质得到进一步去除,系统稳定性更好,从根本上解决有机试剂分解的有机物对锌电积工艺的危害。The purification and cobalt removal process of zinc hydrometallurgy reagent uses organic reagent sodium formate to remove cobalt.There are some problems in the production,such as poor cobalt removal effect,enrichment of organic decomposition products in zinc hydrometallurgy system,difficulty in zinc electrowinning burning plate and melting and casting materials.In this paper,the above problems were analyzed,and the measures of optimizing cobalt removal process,new liquid quality,germanium removal process parameters,and removing nano-zinc sulfide were proposed.Through the implementation of optimization measures,the use of organic reagents is significantly reduced,the enrichment of organic matter in the system is also significantly reduced,the impurities such as cobalt and cadmium in the purified new liquid are further removed,and the system stability is better,which fundamentally solves the harm of organic matter decomposed by organic reagents to zinc electrowinning process.
