2011· Historically and sulfide oxidation filtrates.REVIEWING THE OPERATION OF GOLD ELECTROWINNING CELLS. To a great extent cell-mud handling and filtration and large-scale smelting operations.Electrowinning is a widely used technology in modern metal recovery and sulfide oxidation filtrates.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.
