An extraction system composed of P507 as the extractant and sulfonated kerosene as the diluent was used to separate zinc from a sulfuric acid leachate containing cobalt, manganese and zinc. The effects of key parameters on zinc separation efficiency were investigated, including the volume fraction of P507 in organic phase, saponification degree, pH value of feed, O/W ratio, reaction time, and reaction temperature. The results show that under the following optimal process conditions, including P507 at 20% by volume, saponification degree of 80%, feed pH of 5, O/W ratio of 1∶1, reaction time of 10 min and reaction temperature of 25 ℃, the extraction rate of Zn reaches 99.92%, while the extraction rates of Mn and Co are just 17.41% and 3.69%, respectively, presenting an excellent separation effect.
