The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. 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 invention teaches a deep boiling process for refining diamonds, be they raw or cut and polished. The process provides for initially precleaning the diamonds with solvents including alcohol, acetone, sulfuric acid, hydrogen peroxide, and/or water, to remove surface oils, hydrocarbons and other common surface impurities therefrom. The process then provides the use of separate sealed vessels ...
