Electrorefining – Electrolytic Gold Recovery | Gold Refineries

26/05/2010· 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,

Electrolytic processes for gold and other precious metals ...

12/10/2017· The electrolytic refining process for gold uses hydrochloric acid as the electrolyte. The anode is made of gold alloy and the cathode is usually a thin sheet of high purity gold. The electric current ionises the electrolyte and transfers dissolved gold from the anode to the cathode, thereby increasing the purity of the gold at the cathode.

Extraction of Gold

The extraction of gold by the cyanide-method is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically.

Electrolytic Refining - Mining Fundamentals

The electrolytic process is similar to gold, except that the silver anodes are dissolved in a nitric acid bath. The resulting silver will be about 99.9% pure. Copper – The extraction of copper from other ores through electrolysis involves the deposition of copper on the cathode, and using lead-coated anodes.

Electrowinning and Smelting - Resource Book

The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.
