    Apr 24, 2017 The Wohlwill Process. In 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 100ounce anode, whereas pure gold strips make up the hode. The electrolyte solution is a mix of gold

  • Electrowinning Gekko Gekko Systems

    Electrowinning is the recovery of metals, such as gold and silver, from solution by passing a current through the solution. Electrons from the current chemically reduce the gold and/or silver ions, to form a solid metal compound on the hode. High throughput, stateoftheart electrowinning cells provide a lowcost option for

  • How to Leach Gold Ore With Chlorination Sciencing

    Apr 25, 2017 Gold can be leached from stone through alkaline or acidicbased products, including halogens, such as chlorine, iodine and bromine. Halogens are reactive, nonmetal elements with seven electrons in their outer shell which allow them to easily combine with other elements. The use of chlorine is both the
