Abstract
In an electrolytic process for the desorption of precious metals such as gold and silver, the precious metal cyanocomplexes are loaded onto activated carbon particles packed into a hollow cylindrical graphite container. The container is connected as the anode of an electrolytic cell employing an alkaline solution as electrolyte and graphite, antimony, or copper as cathode. Upon application of an electric current, the precious metal complexes are desorbed and reduced to precious metals on the cathode.
