Abstract

In this study, the process of Cobalt extraction from chloride solution was investigated by using a mixture of TBP, TOPO and Cyanex272 extractants. Process parameters such as the effect of aqueous solution of pH, extractant concentrations, aqueous to organic phase ratio and the stripping with different acids in Cobalt extraction were investigated. The results showed that the obtained mixture from TBP, TOPO and Cyanex272 extractants with concentrations of 0. 2, 0. 1 and 0. 3 mol/l, respectively, is suitable for the optimal extraction of Cobalt with an extraction efficiency above 91. 39%. Sulfuric acid with a concentration of one mole per liter was used as a suitable reagent in the recovery stage with the stripping percent of over than 99. 2%. In this study, a mixed Synergistic system was reported that is very effective in separation of metal ions and can be used in the recovery of lithium batteries by hydrometallurgical method.
