摘　　要：以某湿法炼锌厂为例,叙述了该湿法炼锌厂采用常规浸出工艺,铟水解沉淀以氢氧化铟的形式富集和回收铟,再经过萃取、酸洗、反萃、置换压团、熔炼、电解精炼等过程生产精铟的工艺。Taking a zinc hydrometallurgy plant as an example,the conventional leaching process is adopted in the plant,indium is enriched and recovered by hydrolytic precipitation of indium in the form of indium hydroxide,and then refined indium is produced by extraction,pickling,stripping,replacement pellets,smelting and electrolytic refining.These process are described in this paper.

关 键 词：锌浸出 富集 回收 精铟
