Wohlwill process The electrolytic method of gold refining was first developed by Dr Emil Wohlwill of Norddeutsche Affinerie in Hamburg in 1874 Dr Wohlwill's process is based on the solubility of gold, but the insolubility of silver, in an electrolyte solution of gold chloride (AuCl 3) in hydrochloric acid The impure gold is cast into anodes The gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting By 2000 bc the process of purifying goldsilver alloys with salt to remove the silver Gold processing Britannica Theoretically, it's possible to form gold by the nuclear processes of fusion, fission, and radioactive decay It's easiest for scientists to transmute gold by How Is Gold Formed?
