【摘要】：针对云南某湿法炼锌浸出渣,采用硫酸强化浸出对渣中锌、锗、铁的浸出效果进行研究。正交试验结果表明:最优浸出条件为:溶出温度160℃,硫酸浓度为1.5 mol/L,浸出时间1.5 h,液固比为6。最优浸出条件下,锌和锗的平均浸出率分别高达96.77%和70.86%,有害元素铁的平均浸出率仅为55.44%,在抑制铁浸出的同时,保证了锌锗元素的高效浸出。
[Abstract]:The leaching effect of zinc, germanium and iron in a hydrometallurgical zinc leaching slag in Yunnan Province was studied by enhanced leaching with sulfuric acid. The results of orthogonal experiment showed that the optimum leaching conditions were as follows: dissolution temperature 160 鈩，
