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. Get price
