摘　　要： 某锌精矿中铟含量很高,采用黄钾铁矾法处理该高铟锌精矿,在得到较高锌回收率的同时,大部分的铟进入矾渣,少部分进入高浸渣,从矾渣和高浸渣中可回收得到电铟。锌的浸出率高达98.45%;而95.08%的铟进入铁矾渣可有效回收。生产实践表明采用该工艺,铟的总回收率可达72%,锌的总回收率可达92%。可见,黄钾铁矾法工艺处理高铟锌精矿可以达到综合回收锌和铟的目的。 A kind of zinc concentrate contains high concentration indium. Jarosite process can obtain high recovery rate of zinc, simultaneously, most of indium remains in the jarosite residues and a little part of indium remains in the high acidities leaching residues. Then indium ingot can be obtained from the above two kinds of residues as raw materials. The leaching rate of zinc is up to 98.45%, and 95.08% indium deposited in jarosite residues can be effectively recovered. Production results show that the total recovery rate of indium and zinc can reach up to approximately 72% and 92%, respectively. Obviously,jarosite process can successfully extract both zinc and indium.
