  • Processing, smelting and refining gold World Gold

    2020-7-7  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 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.

  • How to Purify Gold Sciencing

    TechnologyOperationPreparationIn 1874, Dr. Emil Wohlwill of the Norddeutsche Affinerie in Hamburg, Germany, developed a method to purify gold through electrolysis. The unpurified gold ore is fashioned into a 100-ounce anode, whereas pure gold strips make up the cathode. The electrolyte solution is a mix of gold chloride and hydrochloric acid. When an electric current passes from the anode to the cathode through the electrolyte, the gold at the an在sciencing上查看更多信息
