  • Electrolytic processes for gold and other precious metals

    12/10/2017· The electrolytic refining process for gold uses hydrochloric acid as the electrolyte. The anode is made of gold alloy and the cathode is usually a thin sheet of high purity gold. The electric current ionises the electrolyte and transfers dissolved gold from the anode to the cathode, thereby increasing the purity of the gold at the cathode. This refining process is known as the Wohlwill process

  • Electrolytic Refining of Gold

    The method just described aims at leaving gold in an insoluble state at the anode. Other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later. By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in solution. The active agent

  • Electrolytic Refining Mining Fundamentals

    Gold The electrolytic gold recovery process employs hydrochloric acid as an electrolyte, a thin sheet of gold with more than 99.5% purity as a cathode, and a gold alloy anode. Following the ion transfer, high purity gold is transferred onto the cathode. This process is known as the Wohlwill process. The Miller chlorination process is an economical refining process that separates gold of

    WOHLWILL ELECTROLYTIC PROCESS* 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 it produces gold of
