次氧化锌浸出铟后的浸出渣中含有大量矾，从理论上分析了矾产生的原因，考察了浸出过程中控制酸度及添加过量添加剂对铟浸出率的影响，提出了控制矾的生成及破坏矾从而提高铟浸出率的措施。生产实践表明，采取相应措施，铟浸出率可从60％提高至85％以上，浸出渣中铟质量分数可从900 g／t降至100～200 g／t。

There is a lot of jarosite in the leaching residue in the process of low acidic leaching of indium from zinc oxide powder .The generation reasons of jarosite was analyzed .The influence of leaching agent acidity and appropriate additive on leaching of indium w ere examined .T he measures of controlling jarosite generation and destroying jarosite then increasing leaching of indium were pointed out .The production practice shows that leaching rate of indium can increase from 60% to over 85% , mass fraction of indium in leaching residue can decrease to 100-200 g/t .
