硫酸锌溶液净化新工艺研究

我公司的传统硫酸锌中性上清液净化除杂工艺存在锌粉消耗量大、操作环境恶劣、产渣量大等诸多不足,公司引进JS-3型净化剂进行除杂试验,虽然净化后液砷、锑、锗含量较传统工艺稍有偏高,但镉、钴、镍完全达到合格电解液标准。新工艺较传统工艺每立方溶液节约成本15.29元,并且不产生有毒气体,缩短了净化工艺流程,产渣量少,并能产出可以直接外售的钴、镍渣。

Study on New Purification Process of Zinc Sulphate Solution

Traditional purification process of zinc sulphate solution has lots of disadvantages including big consumption of zinc powder, poor working conditions, and large amount of slag. Purification test was carried out with introduced JS-3 cleaning agent. The results show that contents of cadmium, cobalt and nickel can all meet the requirement of qualified electrolyte though contents of arsenic, antimony and germanium in purified solution are higher than those of traditional process. Compared with the traditional purification process, the new process cuts cost by 15.29RMB/m3, and has the advantages of zero poisonous gas output, shortened process flow, little slag output, and production of cobalt and nickel slag ready for sales.
