摘　　要：文章通过湿法炼锌中常规锌粉置换除钴中锑(砷)盐活化作用机理,以及硫酸铜、高锰酸钾对除钴的活化研究,将其按锑盐∶硫酸铜∶高锰酸钾=1∶m∶n进行配比为综合活化剂,并与常规锌粉-锑盐除钴进行对比,能够达到深度净化目的。同时,节约锌粉单耗高达20%以上,可产生可观经济效益,值得同行应用推广。In this paper,the activation mechanism of Sb(As)salt removal from cobalt by replacement of conventional zinc powder in zinc hydrometallurgy and the activation of cobalt removal by copper sulfate and potassium permanganate were studied,the complex activator was prepared with antimony salt∶copper sulfate∶potassium permanganate=1∶m∶n,and was compared with conventional zinc powder-antimony salt for cobalt removal.At the same time,the zinc powder consumption can be saved up to 20%and the considerable economic benefit can be obtained.
