摘要
研究了锌精矿直接浸出时的在浆有机溶剂萃取 ,通过扫描电镜分析比较了浸出前矿粒以及两种不同浸出渣的表面形貌。结果表明 ,四氯乙烯是一种非常有效的萃硫有机溶剂 ,其加入时间控制为 0 .5～ 1.5h。当有机相与无机相 (O/A)之比值小于 1/ 5 0时 ,锌浸出率随O/A比值的增大而增大 ;但当O/A比值超过 1/ 5 0时 。
The effects of solvent extraction in pulp on the leaching of sphalerites with FeCl 3 HCl were investigated. It is found that tetrachloroethylene is an effective organic solvent for sulphur. It is better to add the organic solvent from 0.5 to 1.5?h after the start of the leaching. When the phase ratio O/A is less than 1/50, the zinc recovery increases with the increase of O/A. After that point, the O/A has little effect on the zinc recovery. The mechanism of SIP in the improvement of leaching recovery of sphalerites was identified by SEM morphology analysis.
