Copper Solvent Extraction

Three commercial extractants LIX984N, LIX606N and LIX973N were chosen for the research on Cu2+extraction from the solutions bearing high concentration of sulfuric acid and iron. The ability of Cu2+extraction and Cu/Fe separation performance were totally compared among the three extractants. The results show that LIX606N and LIX973N both possess more powerful ability in Cu2+extraction as compared to LIX984N. But, LIX973N and LIX984N has better Cu/Fe separation performance than LIX606N. According to the performance of Cu2+extraction and Cu/Fe separation, LIX973N is more suitable for extracting Cu2+from the solution rich in sulfuric acid and Fe3+.Effects of sulfuric acid and Fe3+concentration on Cu2+extraction by 20%LIX973N-kerosene have been examined. When aqueous sulfuric acid concentration increases from 23.48g/L to 62.16g/L, Cu2+extraction recovery drops from 60.42% to 25.21%; When aqueous Fe3+concentration increases from 7.03g/L up to 42.94g/L, Fe3+concentration in organic phase increases from 0.26g/L to 0.82g/L.
