wohlwill process. the wohlwill process is an electrolysis process where the metal is first cast into bars which are used as anodes in an electrolyte consisting of gold chloride andor hydrochloric acid. when the electric current passes through the gold or silver, the wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. under the influence of an electric current, the gold migrates to a negatively charged electrode where it is restored to a highly pure wohlwill process the electrolytic method of gold refining was first developed by dr. emil wohlwill of norddeutsche affinerie in hamburg in 1874. dr. wohlwills process is based on the solubility of gold, but the insolubility of silver, in an electrolyte solution of gold chloride in hydrochloric acid. the impure gold is cast into anodes
