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.
The Refining Process. Refiners start with one of two types of gold: a doré bar or scrap. Doré bars are produced by miners and are about 80 percent pure. Refiners increase the purity by separating the other precious metals and less precious metals that are mined with it. Using induction heating, doré bars and scrap are turned into molten metal.

The gold occurring in the alluvium is not refined by any of Nature's processes—but the accompanying minerals or metals are either oxidised or removed hence, in the recovery of gold from reefs impurities are often collected and introduced, thus making it of lower value than the corresponding alluvial gold, and also giving rise to erroneous …
Simply put, the trick to refining gold is to dissolve impure gold in acid such that all the impurities fall out, and then to pull the pure gold back out of your acid solution. Practically,...

1. Dip Samples are Taken from Molten Gold; Refining gold begins with melting the gold in a crucible and taking dip samples to test the millesimal fineness of the gold. This provides measurable purity to benchmark against in the final stages of refinement. 2. Chlorination Separates Impurities from Gold; The Miller process is fast and simple.
Gold's chemical stability is based on the relative instability of the compounds that it forms with oxygen and water—a characteristic that allows gold to be refined from less noble metals by oxidizing the other metals and then separating them from the molten gold as a …
