研究了以两段浸出工艺从含铟锌渣氧粉中浸出铟。试验主要考察了两段酸性浸出中，硫酸初始质量浓度、浸出时间、液固体积质量比、温度、机械活化时间、氧化剂用量等对铟浸出率的影响。试验结果表明：中性浸出对铟有明显的富集作用，机械活化可以强化铟的浸出，常压氧化对铟的强化浸出效果不明显；在硫酸初始质量浓度300 g/L、浸出时间3 h、液固体积质量比3∶1、温度85℃、机械活化60 min的最佳条件下，铟浸出率为90．9％。

Leaching of indium from zinc oxidation slag by two-stages leaching process was studied .The effects of sulfuric acid initial concentration ,leaching time ,the ratio between liquid and solid , temperature ,activated time and KMnO4 dosage on leaching of indium were examined .The results show that the indium is enriched in neutral leaching residue after first-stage leaching .Leaching of indium can be enhanced obviously by mechanical activation ,but atmospheric oxidation doesn't improve the leaching of indium .T he optimum leaching conditions in second-stage leaching process are sulfuric acid initial concentration of 300 g/L ,leaching time of 3 h ,the ratio between liquid and solid 3 ∶ 1 , temperature of 85 ℃ ,mechanically activated of 60 min .Under the optimum conditions ,leaching rate of indium is 90 .9% .
