  • Gold Processing Refining Britannica

    gold processing gold processing refining: gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. two methods are commonly employed for purification: the miller process and the wohlwill process. the miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more may 22, 2018 smelting gold usually involves high-tech and high-cost tools to perform. mostly, mining companies do the procedure, which sees one material bonded to or released from another in the presence of extreme heat. however, prospectors, and people at home, can smelt their old gold using some simple steps.
