The present invention relates to a process for separating a second metal that does not form an anionic complex in the presence of zinc and chloride ions, wherein the zinc and second metal are present in the effluent in the form of ZnCl 2 and a second metal chloride. According to the method of the present invention, the formation of the anion complex is obtained by contacting the effluent with a resin saturated with chloride ions, and in this step, the second metal chloride is extracted with the first eluent, and then the oxidation degree is + II. Characterized in that the steps are to extract zinc (second zinc) with. Generally the second metal is a transition metal such as Cr, Cu, Ni and Fe, more particularly nickel. |
