Processing, smelting and refining gold | World Gold Council

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.

Topical Bible: Refining

The description of refining in Ezekiel 22:18-22 may indicate that a flux (compare "as with lye," Isaiah 1:25 the American Revised Version margin) was sometimes added to the melted metal to dissolve the oxides of copper, lead, tin and iron as they formed, thus leaving the silver pure. Crude processes similar to those described above are used in ...

Puddling (metallurgy) - Wikipedia

This was the ideal material to charge to the puddling furnace. This version of the process was known as 'dry puddling' and continued in use in some places as late as 1890. The alternative to refining gray iron was known as 'wet puddling', also known as 'boiling' or 'pig boiling'. This was invented by a puddler named Joseph Hall at Tipton.
