从锌浸出渣中强化浸出锌锗的试验研究
Experimental Research on Intensified Leaching of Zinc and Germanium from Zinc Leaching Residue
摘要
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.关键词
