Wohlwill
Wohlwill : An electrolytic process for refining gold. The crude gold, which may be made by fusing the anode slimes from the Balbach process, is used as the anode, the cathode is of pure gold, and the electrolyte is a solution of gold chloride in hydrochloric acid. Gold deposits on the cathode. Silver deposits as a sediment of silver chloride. The process is relatively slow, so the interest lost on the inventory of metal in process is significant
