US Pat 4,554,058 1985 Nov; :1-5
An electrolytic process for the desorption of precious metals such as gold and silver. The precious metal complexes are loaded on activated carbon particles that are packed into a hollow, cylindrical graphite container and the container is connected as the anode of an electrolytic cell. The electrolyte is a suitable alkaline solution and the cathode can be graphite, antimony or copper. Upon the application of an electric current, the precious metal complexes are desorbed and reduced to precious metals on the cathode.
