A process for separating metal present as an anlonic complex in a solution which is passed through an electro lytic cell is described. The anode compartment contains sodium sulfate. The compartment is separated from the solution by an anion-exchange membrane derived from an organic polymer containing co-valently bound chlorine by replacing the chlorine with basic nitrogen- containing groups. The organic polymer is polyvinyl. Hexamethylene diamine is used to replace the chlorine in the polymer. The cathode compartment is separated from the solution by the anion-exchange membrane and contains either sodium sulfate or magnesium sulfate. This method may be applied to either thorium or uranium by introducing the metal in the form of a pulp with a solids content of at least 50% by weight and with a pH between 1.5 and 2.0. The solution may be that from a sulfuric acid leach process. (N.W.R.)
