How to Refine Gold in the Fire eHow

2020-7-24  Gold can be mixed with other metals like copper, which is used in red gold, or mercury, which is used in dental gold. Gold is a very pliable metal and its melting point is relatively low; therefore, refining it by melting it and extracting the other metals from it is a practical process.

Refining Gold HowStuffWorks

­The final stage of gold production -- refining-- involves removing impurities that remain after the smelting process.Refining companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. A sample is then taken to a lab for tests, or

Processing, smelting and refining gold World Gold

2020-7-20  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.

Using Borax Flux to Refine Gold Manhattan Gold

2013-8-7  In metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. With some borax, heat, and a little know-how, it’s possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold.
