Electrorefining – Electrolytic Gold Recovery Gold Refineries

Electrorefining is a process that uses the principals of electrolysis to recover gold from an alloy typically found in jewelry. Electrolytic gold recovery begins with a bath of hydrochloric acid, which forms the electrolyte. The cathode is usually a thin sheet of 24K gold, but it needs to be better than 99.5% pure. The gold alloy (source material) comprises the anode. This method is called the ...

How Gold Electroplating Is Done - Sharretts Plating Company

Gold electroplating is a very safe process when done by professionals. One concern with gold plating, however, is that it masks the other metals. If you have a metal allergy, you may be exposed to the allergen as the gold plating tarnishes and the coating wears away. Nickel is the main cause of metal allergens, so an allergic reaction may appear once the nickel is exposed. Re-plating can ...

Electrowinning and Smelting - Resource Book

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, constructed of non-conducting plastic material. The cell contains a set of cathodes (negative electrodes) and anodes (positive electrodes) immersed in the gold ...
