Abstract
A process for the selective concentration of metal values in solution wherein said metal-containing solution is contacted with a multiple-phase system having a common solvent, thereby causing the preferential migration of metal values into one phase of said multiple-phase system. The phases of the system may then be isolated and the metal values recovered therefrom by conventional techniques.
