  • Simple Methods of Gold Purification

    · Refining Retorted Gold The purification of such alluvial gold alloys is a simple matter The high specific gravity of the metal allows of separation from most admixed materials by some process of elutriation, or water concentration, or, in arid regions, by dry blowingThis is a free tutorial on gold recovery method using nitric acid to extract pure gold from old gold and scraps of gold by process of dissolving unwanted metals When I use this refining method, I regard the purity of the gold as 22kt, and I alloy it accordingly down to 18kt or 14ktGold Refining Purify Process jewelry tutorials· 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 995 percent purity The Wohlwill process increases purity to about 9999 percent by electrolysisGold Refining | From Gold Ore to Doré | World Gold Council
