【Abstract】 The extractability of cobalt （Ⅱ） and nickel （Ⅱ） in ammoniacal ammo- nium sulfate solution with the oxime N₅₃₀ as extractant and the way of sepa- rating the two metallic elements with N₅₃₀ have been studied.The results of our investigation have shown:it is difficult to separate cobalt （Ⅱ） and nickel （Ⅱ） at the extraction stage,but the separation can be achieved easily by using appropriate stripping solution （sulphuric acid solution and mixed Solu- tion of sodium chloride and hydrochloric acid） at the back—extraction stage.更多还原
