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.
