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1.5h,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 intensified leaching using H2SO4 was developed to study the leaching effect of Zinc (Zn2+),Germanium(Ge4+) and Ferrum (Fe3+) from Yunnan some zinc leaching residue.Based on the orthogonal test results,the optimal average leaching rate of Zn and Ge reached 96.77% and 70.86% respectively with 1.5 mol/L H2SO4 at 160 ℃and liquid/solid ratio of 6 for 90 min,the leaching rate of the harmful element Fe was only 55.44%.The intensified leaching method reached high leaching rate of Zn and Ge,depression leaching of Fe.
