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 (cathode), where it is restored to a highly pure metallic state, leaving the impurities as a separate solution or residueGet Price
Gold electrolysis was invented by Emil Wholwill in 1874. But various versions of this process have been developed over the years. It is an electrochemical process which has been applied in many large-scale gold-refining establishments or industries. The principle of gold electrolysis is very straightforward or simple: Dore bar, which is a cast gold ingot at 95% plus purity is used as the anodeGet Price
