Separation of copper from a sulfuric acid leaching solution of manganese nodules was carried out by using a liquid surfactant membrane containing LIX 65N as a mobile carrier and glutamic acid di -oleylester ribitol as a surfactant. The permeation rate of copper ion is explained by taking account of the interfacial reaction between LIX 65N and copper ion and the mass transfer of copper ion in external aqueous solution along with the permeation of water from external to internal aqueous solutions. It is found that the separation factor of copper ion against ferric ion and the permeation rate of copper ion in sulfate media are enhanced by a liquid surfactant membrane containing sodium dioleyl sulfosuccinate as an additive in addition to the above system.
