The result is 98% pure gold, which is then electrolytically refined to remove platinum and palladium. Wohlwill Process. ... It is possible to refine gold without the use of large-scale, expensive chemical procedures. The process involves first adding nitric acid to gold, then adding hydrochloric or muriatic acid. ... Powell, Jack. "Gold ...
Following beneficiation to concentrate the mineral value, the concentrate is specifically processed to further extract and/or refine the metal, thus preparing it for its final use or for incorporation into physical or chemical manufacturing.
Platinum Metals Rev., 1963, 7, (41,136-143 136 The earlier stages of the mining and recovery of the platinum metals from the Rustenburg Platinum Mines have been reviewed in some detail in this journal (I), while the geology of the Bushveld Igneous Complex and the platinum reefs-constituting

Refining is an industrial process that transform impure Gold by chemical, physical or other means into high pure Gold. The most used method for Gold refining is based on ‘Aqua Regia’ but alternative methods, some of them more eco friendly can be proposed by CLM, including electrochemical methods.
Used alone, physical methods are sometimes too labor intensive and expensive to justify the level of invasive plant control achieved, particularly when applied to well-established or large-scale infestations.
The Wohlwill and Miller processes are the two main methods used to refine gold today. The Wohlwill process creates gold to a high level of purity (99.999 percent). It is an electrochemical process that was invented by Emil Wohlwill in 1875.
Floatation, cyanidation, and the carbon-in-pulp method are 3 processes used to refine gold. They can be used alone or in combination with one another. ... Two other methods of gold refining are amalgamotion and smelting. ... Smelting involves heating the gold with a chemical substance called flux. The flux bonds with the contaminants and floats ...
