Title: OXALATE PROCESS FOR SEPARATING ELEMENT 94

Abstract

A process is presented for separating plutonium values in the tetravalent state from hexavalent uranium with which it is associated in aqueous solutions. This separation is aceomplished by forming a thorium oxalate precipitate in order to carry only the plutonium. By carefully regulating the acidity of the solution and the oxalate ion concentration, the precipitation of uranium oxalate may be avoided.
