摘要： 采用萃取剂LIX984N研究了3种含铜细菌浸出液(KLTK,HTS和LW)的萃取效果.萃取剂LIX984N萃取铜的最佳条件:pH为2.5,有机相与水相的体积比为3∶2,萃取剂的质量分数为20%,萃取原液Cu2+的质量浓度为3 g.L-1,萃取时间为11 min.实验表明经过一级萃取后,萃取率在99%以上,一级反萃率在95%以上,二级反萃率在97%以上,萃取效果明显.

Abstract: The extraction efficiencies of three kinds bioleaching solutions containing copper (HTS, KLTK and LW) were studied using LIX984N as the extracting agent. The optimum condition of extraction is 2.5 of pH value, 3:2 of volume ratio of organic material to water, 20% of mass fraction of extracting agent, 3 g·L-1 of Cu2+ mass concentration of original extraction fluid, and 11 min extraction time. The experiment results indicated that the first stage extraction efficiency can reach above 99%, the first stage back extraction efficiency is above 95%, and the second stage back extraction efficiency is above 97%. The extraction efficiency is high.
