为寻求降低湿法炼锌溶液净化过程中的锌粉消耗的有效途径 ,研究了两段逆锑净化除钴工艺中净化温度、锌粉加入量、锌粉粒度、搅拌速度等因素对净化效果的影响 .结果表明 ,净化温度和锌粉加入量是影响净化除钴效果的主要因素 ,在锌粉用量≥ 1 .6g·L- 1 、温度 85℃、搅拌速度≥ 30 0r/min、锌粉粒度较细的条件下 ,可使净化后溶液 [Co2 + ]≤ 0 .50mg·L- 1 ,这对实际生产有重要的指导意义 In order to find an effective way to reduce the zinc consumption in the purification process of zinc hydrometallurgy, the effects of purification temperature, amount of zinc powder, zinc particle size, stirring speed and other factors on the purifying effect .The results show that the purification temperature and the amount of zinc powder are the main factors that affect the removal of cobalt, and the optimum conditions are as follows: the dosage of zinc powder ≥1.6g · L -1, the temperature of 85 ℃, the stirring speed ≥30 0r / min, Fine conditions, can make the purified solution [Co2 +] ≤ 0.50mg · L-1, which is an important guide for the actual production
