湿法炼锌过程中铟的富集回收研究

摘要

The zinc oxide leaching solution contains indium 90 mg·L-1 in 100 kt/a zinc smelting process of Shangluo Zinc Smeltery, and has a high recovery value of indium. In order to optimize indium enrichment ve recovery process, zinc powder replacement method and high purity zinc oxide hydrolysis precipitation method in indium enrichment process is comparatively studied. It is found that better menthod in indium recovery is zinc powder replacement method.%商洛炼锌厂10万吨锌冶炼工艺中，氧化锌浸出液含铟90nag·L-1，具有一定的回收价值。为了优化锌冶炼综合回收利用过程中铟的富集方法，通过锌粉置换法和高纯氧化锌水解沉淀法富集铟的工艺的对比研究，结果显示，选用锌粉置换法富集回收铟比较有利于生产。
