硫酸锌溶液净化除钴研究现状
|
摘要
在加压湿法炼锌过程中,硫酸锌溶液中的钴、镍、砷、锑、锗等杂质需要净化脱除,以便后续电积正常进行。这些杂质中,钴很难被净化脱除。钴难以净化脱除的原因及机制,国内外都有大量研究,但迄今为止尚未形成统一认识。介绍了硫酸锌溶液中净化除钴研究现状,指出研究除钴机制、开发除钴试剂是未来的发展方向。
In the process of zinc hydrometallurgy by pressure leaching,cobalt,nickel,arsenic,antimony,germanium and other impurities in the zinc sulfate solution need to be removed.Cobalt is especially difficult to be removed.At home and abroad,there is a great deal of research on the causes and mechanisms of purification and removal of cobalt,but so far there is no unified understanding.In this paper,the research status on purifying and removing cobalt from zinc sulfate solution are introduced.The works on mechanism and new reagent for removal of cobalt are the direction.
