the electrolytic silver refining process is similar to gold, except that the silver anodes are dissolved in a bath of nitric acid. the resulting cathodes are 99.9% pure silver. as with small gold bar production, these cathodes are melted, granulated and cast into retail sized bars (most common being 100oz or kilo).
dear sir, i am helping a patron of mine do research on the electrolytic refining process of gold (primarily) and silver (secondly). we are having trouble finding resources that explain the process fully, but i have ordered hummel's wohlwill electrolytic gold, platinum, and palladium refining.
to further refine gold and silver to 99.99% the cost effective once through wohlwill electrolytic refining process is used. the refinery continually investigates refining technology developments that could make its operations more efficient and cost effective.
electrowinning theory gold is recovered from pregnant (gold bearing) solution by the process of electrowinning. an electric current is passed through the solution causing solid gold to plate out on steel wool cathodes. electrowinning is performed in cells
the electrolytic process involves suspending plates of pure gold alternately with plates of impure gold in a cell containing a solution of gold chloride and hydrochloric acid.
gold refining systems safe & simple machines and for the first time ever, gold processing can be done with a high level of confidence and safety, from a very small jewelry business to medium scale refinery. the process is simple and easy. by using our
refining to commercially accepted purities of gold and silver miller process and electrolytic refining for gold pyrometallurgic and electrolytic refining for silver products to add value through various commercial products of gold and silver. includes: large bars kilo
electrolytic refining the purification uses an electrolyte of copper(ii) sulfate solution, impure copper anodes, and strips of high purity copper for the cathodes. the diagram shows a very simplified view of a cell. at the cathode, copper(ii) ions are deposited as copper.
electrowinning is the oldest industrial electrolytic process. the english chemist humphry davy obtained sodium metal in elemental form for the first time in 1807 by the electrolysis of molten sodium hydroxide.electrorefining of copper was first demonstrated

wohlwill process is a process that is used to refine gold to the highest degree of purity (99.999%) with a process of industrial scale chemical procedures. wohlwill process the electrolytic method of gold refining was first developed by dr. emil wohlwill of norddeutsche affinerie in hamburg in 1874.
na also pioneered the electrolytic refining process and built the world's first electrolytic refinery in 1876. refining: the pressure's on to upgrade facilities pamp, like a majority of the world's accredited refiners, has adopted the cleaner, simpler and more effective treatment process of electrolytic refining rather than chlorination or wet chemical parting for its manufacturing activities.
