  • Gold Refining | From Gold Ore to Doré | World Gold Council

    The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process 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 it08/02/2018· Using bulldozer and excavator stockpiles the goldbearing gravels near the gold mining wash plant, feeds gravels into the wash plant from feeding hopper (mount a vibrating screen to primary classify the goldbearing gravels), the oversize material slides out, and the undersize material is mixed with water flow through the gold concentrator machines like gold centrifugal concentrator, portableSmall and Portable Gold Wash Plant JXSC Machine23/03/2016· 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 blowing The coarser particles are readily picked out, but the finer are usually admixed with heavy sands, consisting of crushed zircons, garnets, cassiteriteSimple Methods of Gold Purification
