OPTIMIZING THE OPERATING CONDITIONS OF GOLD …
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. The quality of the final bullion is affected by the presence of base metals. This project focuses on the assessment of the existing operating parameters particularly with regards to elution and electrowinning processes …
AARL Carbon Stripping System Operation: Elution ...
One bed volume (thirty minutes) into the elution stage the eluate pump is started and pregnant solution from the eluate tank, is pumped up into the electrowinning cell on the first floor of the goldroom. It then flows back into the eluate tank. As the solution flows through the electrowinning cell, gold is plated on to the steel wool cathodes.
Electrowinning - an overview | ScienceDirect Topics
Electrowinning is most often used to recover gold and silver from eluates produced by the elution of activated carbon. [Ed.: Electrowinning of gold is regarded as a mature technology; hence, full revision and update of this chapter from the first edition version was not warranted.

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.
Modular Elution Circuits with Gold Room | Como Engineers
By pressurising the electrowinning cell, the gold-cyanide complex in electrowinning is destabilised and increases the electrowinning efficiency, lowering solution tenors returning back to the elution column and providing the optimal kinetics for rapid eluting of the precious metals off the loaded carbon.
Elution and Carbon Reactivation - Resource book
The gold can then be removed from the solution by electrowinning onto steel wool cathodes (refer ‘Electrowinning and Smelting’ module). As well as stripping the gold from the carbon, the elution process incorporates an acid wash stage, which removes inorganic foulants from the carbon. Foulants reduce the activity, and hence gold adsorbing ...
