Then, most of the copper and silver can be dissolved with nitric acid, leaving the gold undissolved. The gold, which is not quite pure, is then purified by dissolving it in aqua regia and then selectively precipitating it. If the gold is greater than 25%, this will not work - the gold will form a crust on the surface and prevent the penetration of the nitric. Similar blockage would occur in the electrolytic method you …

Wohlwill electrolytic refining process for gold
06.03.2008 · To refine gold you have to lower the percentage of gold by using silver or copper, theoretically to 25%. meaning the gold content of the metal is 25%. But in practice its best to lower it to around 15- 20%. After putting nitric acid you heat it to boiling temperature until it stops giving out red smoke, Be careful as bubbles form and might overflow, so just lower the fire. then you should wash ...
Electrolysis - Wikipedia
In chemistry and manufacturing, electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous stone reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell.The voltage that is needed for electrolysis to occur is called the decomposition potential.

Electrorefining of Copper
Virtually all copper produced from ore receives an electrolytic treatment at some stage either via electrorefining from impure anodes or electrowinning from leach or solvent- extraction liquors. Electrorefining produces the majority of cathode copper ca. 95% as opposed to ca. 5% from electrowinning). The electrorefining step serves two purposes: 1) Elimination of unwanted impurities; …
