| Abstract: | In this paper,the factors of PH.Rot, Rew,and intensity of mixture.which influence the results of separation of concentrated copper by liquid membrane.were discussed.The interrelating factors of liquid membrane separation of copper have been studied by orthognal designing method.The traditional extraction method was compared with liquid membrane method.The method of extraction of copper by metal chelate involves many working processes and it is time -consuming and expensive.The test shows that the separation of concentrated copper by liquid membrane method is more effective. |
