Abstract: The present invention is a novel electrochemical process for separating and/or purifying the components of mixed materials such as alloys, rare earths, spent reactor fuel rods, isotopes, or other normally difficult to separate materials which carry the same sign of the ionic charge when in solution (positive, negative or neutral), but which can be made to exhibit a difference in oxidation potential, comprising (a) passing a current through an electrolyte containing the dissolved materials to be separated (separants), carrier-formers and a solvent and (b) refluxing the separants, until the desired degree of purity is reached. The carrier-formers, which may carry a positive, negative or neutral charge, are capable of interacting with the separants to form separant-carriers such that for each separant there is at least one separant-carrier having a positive charge and one separant-carrier having a negative charge, such that each separant is divided between a pair of oppositely directed carriers.
