The Wohlwill process is an industrial-scale chemical procedure used to refine gold to the highest degree of purity (99.999%). [1] The process was invented in 1874 by Emil Wohlwill. This electrochemical process involves using a cast gold ingot, often called a Doré bar, of 95%+ gold to serve as an anode. Lower percentages of gold in the anode will interfere with the reaction, especially when the contaminating metal is silver or one of the platinum group elements.

· While the Miller process "is rapid and simple," the Council notes, it produces gold that''s only about 99.95-percent pure. The Wohlwill process, however, boosts purity to 99.99 percent through electrolysis. In this process, a casting of impure gold is dropped into an electrolyte solution of hydrochloric acid and gold chloride.
