摘　　要：采用三氧化二锑对湿法炼锌的硫酸锌溶液进行净化除钴。考察锌粉用量、三氧化二锑用量、锌粉粒度、搅拌速度、温度、时间等对净化除钴效果的影响。结果表明，细粒度锌粉和强烈搅拌除钴效果较好，在合适的温度和时间下也能达到净化要求。最优除钴工艺条件为：三氧化二锑3mg／L，锌粉2g／L，锌粉粒度0．074-0．050mm，搅拌转速300r／min，温度85℃和时间90min。Cobalt in zinc sulfate solution from zinc hydrometallurgy was purified with antimony trioxide. The effects of dosage of zinc powder and antimony trioxide, particle size of zinc powder, stirring rate, tem- perature, and time on cobalt removal were examined. The results show that good cobalt removal effect can be achieved with fine-grained zinc powder by strong mixing and purification requirements can be met in ap- propriate temperature and time. The optimum conditions for cobalt removal include dosage of Sb2Oa of 3 rag/L, dosage of zinc powder of 2 g/L, zinc powder particle size of 0. 074-0. 050 mm, stirring rate of 300 r/rain, temperature of 85℃ and time of 90 min.
