Electrowinning of gold copper ores - …
The copper content is not high enough for economic recovery but its high enough to cause problems in our CIP circuit and electrowinning. A typical elution would produce about 4kgs of gold and 5kgs of copper. The copper makes it difficult to strip the gold off the steel mesh cathodes. Which would be the best stage to eliminate copper, during ...
OPTIMIZING THE OPERATING CONDITIONS OF GOLD ELUTION …
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 ...

Electrowinning - Wikipedia
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. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non ...
Electrowinning - an overview | ScienceDirect Topics
Electrowinning produces pure metallic copper from leach/SX electrolytes. In 2010, about 4.5 million tonnes of pure copper were electrowon. Electrowinning entails applying an electrical potential between inert Pb-alloy anodes and stainless steel (occasionally copper) cathodes in CuSO 4 –H 2 SO 4 electrolyte. Pure copper electroplates on the ...
