摘　　要：研究了采用还原挥发法从铁铟渣中回收铟,考察了焦渣质量比、还原温度和还原时间对铟挥发率的影响。试验结果表明:在焦渣质量比为0.5、还原温度为1 250℃、还原时间90 min条件下,铟回收率达89.48%。Recovery of indium from In-Fe slag by reduction volatilization were researched. The effect of coke-slag mass ratio, reduction temperature and time on indium recovery was examined. The results showed that the highest indium recovery of 89.48% was achieved at the conditions of coke-slag mass ratio of O. 5,reduction temperature of 1 250 ℃ and time of 90 minutes,respectively.
