摘　　要：研究了用新型除钴剂AnBm从湿法炼锌硫酸盐溶液中除钴，考察了影响钴沉降的几个因素。试验结果表明：在氧化剂加入量42mg／L，脱钴剂加入量2．4g／L，反应时间50～60min，温度70～80℃，pH4．1～5之间条件下，钴脱除效率达97％以上，溶液中钴质量浓度降至0．7mg／L以下，满足电积锌的要求。Removal of cobalt from zinc sulfate solution in zinc hydrometallurgy was researched using a new cobalt removal reagent AnBm. The factors of affecting electrodeposit of cobalt were examined. The experimental results showed that removing of cobalt could reach to 97% and the mass concentration of cobalt in solution could decrease under 0.7 mg/L at the conditions of oxidizer Fe^3＋ of 42 mg/L and cobalt removal reagent of 2. 4 g/L, reaction time of 50 to 60 minutes, reaction temperature of 70 to 80 ℃ and pH of 4.1 to 5 .
