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 produces gold of only about 99.5 percent purity. the wohlwill process increases purity to about 99.99 percent by electrolysis.
the final stage of gold production -- refining-- involves removing impurities that remain after the smelting process.refining companies receive dor 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 mining.Feb 29, 2016 small miners employ this process due to alluvial deposits contain free gold, the process is fast and efficient, the final product has a high gold grade and recoveries are between 80 to 95, commercialization is fast and simple without brokers, the process is simple and is not necessary a big investment or very special technical knowledge, the mercury can be reused and its losses are minimized, the final product weight is small and can be transported easily from the process mining.
A lower grade gold ore would contain something like 5 grams per tonne 5 parts per million. so gold ore needs to be concentrated by about 1,000 times above its average dispersion to become viable for gold mining. the process of gold concentration happens both above and below the surface of the earth.
