In this study solvent extraction process has been used for separation of cadmium and copper from sulphate solution. A phosphoric acid extractant (D2EHPA) and an oxime extractant (MEX) in kerosene diluent were used as cadmium and copper extractants, respectively. The results showed that 1g/L cadmium could be extracted by 30–35% (v/v) D2EHPA at the pH of 3.5–4. Cadmium separation factor over copper...
