The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about percent purity. The Wohlwill process increases purity to about percent by electrolysis.

Extraction of Metals | Good Science
Very reactive metals are extracted by a process called electrolysis. Electrolysis is a nonspontaneous redox reaction, which involves the passing of an electric current through molten ore. The electric current causes electrons to be added to metal ions, thus reducing them to metal atoms. Click image to preview the worksheet for this lesson.
