<p>The invention relates to a method for the separation of zinc an 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 inventive method is characterized in that formation of the anionic complex is obtained by bringing the effluent into contact with the resin saturated with chloride ions, and in that said inventive method comprises the following steps: extraction of the second metal chloride by means of a first eluent, then 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.</p> |
