摘　　要：针对高铁氧化锌物料两段浸出锌铁铟工艺存在的一些问题进行工艺改造,增加高酸浸出、还原、除铁工序,工艺改造后,锌、铟、Fe浸出率均得到提高,浸出渣铅品位也明显提高。Some problems exist in the process of two-stage leaching zinc, indium and iron from high-iron zinc oxide. After the process being improved by adding the procedure of acidic leaching, reduction and removal iron, the leaching rate of zinc, indium and iron increase, and the grade of lead slag increase significantly.
