There are two main methods of refining gold—the Wohlwill process or the Miller process. The Wohlwill process was invented in 1875 by Emil Wohlwill and produces gold to a high degree of purity (99.999 percent). The Wohlwill process is an electrochemical process. The Miller process produces a slightly lower purity of gold, only 99.95 percent pure.
