Description
Summary:The solvent extraction of copper and iron from bioleaching solutions of PCBs with LIX 860N-IC and next stripping test with H<sub>2</sub>SO<sub>4</sub> were investigated. In test the effect of varying sulfuric acid concentration on stripping rate of Cu and Fe and also phase ratio (O : A) were determined. It was found that the stripping rate of copper increases with the sulfuric acid concentration. The optimal concentration of H<sub>2</sub>SO<sub>4</sub> is suggested to be about 150 g/L and phase ratio O:A = 1:1.
