Abstract
Nobel metals such as silver and gold are removed from solutions containing them in an electrolytic process in which the cathode of an electrolytic cell comprises a carbon fiber mass. Metal ions are plated out on to the carbon fibers which exhibit a large surface area in the highly porous cathode. Recovery of the metal values is obtained through heating the plated fiber mass to a temperature sufficient to burn off the carbon fibers.
