Wohlwill Process Gold Refining Finest Known
1998年5月17日 Wohlwill process is a process that is used to refine gold to the highest degree of purity (99999%) with a process of industrial scale chemical procedures Many people do not realize or even think about he purity of their goldThe Wohlwill process is an industrialscale chemical procedure used to refine gold to the highest degree of purity (99999%) The process was invented in 1874 by Emil Wohlwill This electrochemical process involves using a cast gold ingot, often called a Doré bar, of 95%+ gold to serve as an anode Lower percentages of gold in the anode will interfere with the reaction, especially when the contaminating metal is silver or one of the platinum group elements The cathodesWohlwill process Wikipedia2011年5月26日 An old and wellestablished process, the Wohlwill method is widely used in major gold refineries, often in conjunction with the Miller process (For typical Wohlwill Electrolytic Process Gold Refining Metal Extraction
