2022-7-9 The process causes heavier molten impurities to settle to the bottom, while the lighter molten gold floats above it. This happens for the same reason that oil floats on water owing to its density. Finally, the molten gold is extracted and cooled in the shape of the gold bar that we all know of. It takes 4 minutes for the gold to solidify

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 Miller process is rapid and simple, but it
