摘要
A method for the separation of zinc and a second metal which does not form an anionic complex in the presence of chloride ions, zinc and the second metal being present in an effluent in the form of ZnCl2 and a second metal chloride. The formation of the anionic complex is obtained by bringing the effluent into contact with the resin saturated with chloride ions. The second metal chloride is extracted by means of a first eluent, followed by extraction of zinc with a degree of oxidation of +II. Generally, the second metal is a transition metal such as Cr, Cu, Ni, Fe and, more specifically, nickel.
