A process for the selective removal of a least a portion of at least one precious metal in the form of a metal-cyanide complex from an ion-exchange resin to which the precious metal and at least one base metal-cyanide complex are bound, wherein the at least one precious metal is eluted from the resing by contacting the resin with an eluent comprising at least one counter-ion contained in a solvent selected from an organic solvent or a combination of an organic solvent and an aqueous solvent.
