摘　　要：通过对富含铟锡的硅氟酸铅电解液进行净化萃取,实现用20%P204+80%260#煤油有机相可将铟锡萃取与铅电解液水相分离,用6N盐酸反萃净化有机相再生循环使用,反萃液通过锌板置换回收铟,铟总直收率为93%。Extraction and purification of fluosilicic acid electrolyte enriched with indium and tin was carried out,the aqueous phase of indium tin extraction and lead electrolyte was separated by 20%P204+80%260#kerosene organic phase,the reverse extraction purification of organic phase was done by 6 N hydrochloric acid for reprocessing cycle,the strip liquor was used for indium recycle through zinc plate replacement,the total direct recovery rate of indium is 93%.
