Electrowinning and Smelting Resource Book

Electrowinning and smelting are the final stages of gold production. 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.

Extracting Gold HowStuffWorks

Leaching dissolves the gold out of the ore using a chemical solvent. Finally, the gold-bearing solution is ready for electrowinning, which recovers the gold from the leaching chemicals. In electrowinning, operators pour the gold-bearing solution into a special container known as a cell.

Electrowinning Anodes ULTRANODE

Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal.

Processes Gekko Systems

Electrowinning offers a significantly higher efficiency of silver recovery with low operating costs, compared to zinc precipitation methods. In addition, electrowinning produces a very clean silver product that is straightforward to smelt. Cyanide leaching is commonly used worldwide for recovering gold from ore slurries or ore heaps.

OPTIMIZING THE OPERATING CONDITIONS OF GOLD

West Province. The mine produces around 450 kg of gold a month. The ores from the mine are treated in a separate stream at Kopanang Gold Plant. The Kopanang Gold Plant is a modern plant that uses mill-leach-CIP- electrowinning processes. The gold from the electrowinning process is smelted centrally in another plant situated 5 km away from Kopanang.

Electrowinning gold processing Rigaku Global Website

After the gold is leached out of the ore, it is typically absorbed onto activated carbon in processes such as Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), or Carbon Column (CC). Once absorbed, the gold is stripped from the Carbon and the impregnated stripping solution fed into the electrowinning process where the gold is recovered by electrolysis.
