Ever wondered how gold and silver refining is carried out? Gold Refining. Gold mines process ore using various techniques to produce an alloy composed primarily of gold and silver, which is called a doré bar. The composition of doré can vary significantly between mines, but generally the gold doré bars The Perth Mint processes are composed of between 70-80% gold and 10-15% silver.

OBTENER PRECIO >>The Miller chlorine process is a refining process used to refine large amounts of gold with chlorine gas. When chlorine gas is injected into molten gold the chlorine forms chlorides with less noble metals. The chlorides can then be easily removed as they will not alloy with the gold.

Unlike the Wolhwill Process described earlier in this series the Miller Process doesn't use electricity but rather uses a stream of chlorine gas that is passed through a crucible of molten gold that produces gold that is 99.95 Fine. It works to remove all the impurities because gold is least affected by chlorine so all the other impurities are removed as chloride slag floating on the surface of the molten gold where it is .
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.
