Creators

Description

A process for the recovery of at least one of uranium and vanadium from an aqueous liquor is claimed. It comprises: (a) treating the liquor with a low molecular weight completely water-miscible solvent selected from the group consisting of methanol, iso-propyl alcohol or acetone to form at least two phases; (b) separating the phases; (c) recovering the solvent from the first phase as the azeotropic solvent/water mixture by simple, non-fractional distillation and recycling the mixture to step (a); and (d) recovering metal values from a second one of the phases
