| 摘 要： | 以低品位硫化矿的资源综合利用为背景,研究了D2EHPA和D2EHPATOA两个不同体系萃锌的适宜条件.实验结果表明, D2EHPATOA协萃体系在萃取与反萃取的难易程度以及经济效益等方面均优于单独D2EHPA体系.在此基础上,提出了从细菌浸出液中回收锌的工艺.

| Abstract: | A study was carried out to find out the suitable conditions for zinc extraction from acidic zinc sulfate solution by two different extractant systems of di-(2-ethylhexy)-dithiophosphoric acid (D2EHPA) and D2EHPA-Trioctylamine(TOA) respectively in the background of comprehensive utilization of sulfureted sodium. The result shows that the D2EHPA-TOA synergistic extractant system is prior to the D2EHPA one without TOA when the degrees of extraction and strip and the economic benefits are taken into account. A technique to reclaim zinc from bacterial leach solution is suggested. |
