  • Electrolytic Refining of Gold

    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 in causing the solution of the gold is chlorine; this transforms the silver in the

  • Electrolytic Refining: Silver Gold Copper

    The electrolytic process of gold-refining possesses three advantages that are important in mint-work. First, it produces purer gold than the old processes. The elimination of the last trace of silver from the gold removes the brittleness from the ingots used for coinage, so that they roll and press much better than alloys of the same fineness in gold, but made of slightly impure gold. Second

  • Processing, smelting and refining gold World Gold Council

    Processing, smelting and refining gold. From ore to doré . Cyanidation. More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of

  • Electrolytic processes for gold and other precious metals

    Electrolytic Methods Used in Refining Processes of Gold and Other Precious Metals. Electrolysis is an electro-chemical process where an electrical current stream is flowing between two electrodes and through an electrolyte.This process involves the transfer of metal ions through the ionised electrolyte solution, depositing positive ions on the cathode and negative ions on the anode.

  • Electrolytic Refining Meaning, Electrorefining of Copper

    In the process of electrolytic gold refining, hydrochloric acid is used as an electrolyte. A thin sheet of gold is made the cathode and a gold alloy is made the anode. When ion transfer takes place a pure gold with higher purity rate is transferred to the cathode. This method is also called as the cycle of Wohlwill. Silver. In a similar manner, crude silver is made the anode and more refined

  • Purification of Gold by Electrolysis

    The Moebius Process of Purification of Gold by Electrolysis is now in successful operation and is said to be specially suitable for refining copper bullion containing large proportions of silver and gold with small quantities of lead, platinum, and other metals, but is chiefly used in parting dore silver containing not more than 20 per 1,000 of base metals. The apparatus required consists of a

  • Refining (metallurgy) Wikipedia

    Gold and silver preferentially dissolved in this, thus providing a means of recovering these precious metals. To produce purer copper suitable for making copper plates or hollow-ware, further melting processes were undertaken, using charcoal as fuel. The repeated application of such fire-refining processes was capable of producing copper that was 99.25% pure. Electrolytic refining. The purest
