摘　　要：稀散金属铟独立矿床少,常伴生在锌硫化矿中,湿法或火法炼锌时富集到多种渣中,铟铁酸锌等难浸出物的存在使铟的回收工艺复杂,且回收率低。重点介绍了常规酸浸、加压富氧酸浸、热酸浸出、焙烧预处理—浸出、氯盐浸出和复合场强化铟浸出等锌固废提铟浸出工艺。指出未来辅助使用复合外场或联合多种方法从内部破坏难溶物结构,实现铟铁分离和铟铁酸锌的溶解,革新锌固废提铟工艺,研发新型萃取剂均可成为未来发展方向。There are few independent deposits of scattered metal indium,which are often associated with zinc sulfide ores.In hydrometallurgy or pyrometallurgy,indium is enriched in a variety of slag.The existence of refractory materials such as zinc indium ferrite makes the indium recovery process complex and the recovery rate low.The processes of extracting indium from zinc solid waste,including conventional acid leaching,pressurized oxygen enriched acid leaching,hot acid leaching,roasting pretreatment—leaching,chloride leaching and complex field enhanced indium leaching,were introduced.It is pointed out that in the future,the auxiliary use of compound external field or combination of various methods to destroy the structure of insoluble substances from the inside,to realize the separation of indium and iron and the dissolution of zinc indium ferrite,to innovate the extraction process of indium from zinc solid waste,and to develop new extractants may become the future development direction.
