PROCESS FOR SEPARATING ZINC FROM A SECOND METAL THAT DOESN'T FORM ANIONIC COMPLEX IN THE PRESENCE OF CHLORIDE IONS

摘要

The present invention relates to a process for the separation of zinc and a second metal which does not form an anionic complex in the presence of chloride ions, the zinc and the second metal being present in an effluent in the form of ZnCl2 and of chloride of second metal. .According to the invention, this process comprises the steps of: - formation and fixing of the anionic complex ZnCl3- on a resin, - extraction of the chloride of second metal by means of a first eluent, then - extraction of zinc to the degree of oxidation + II.
