Electrowinning of gold copper ores Hydrometallurgy

Hie guys. I am having problems with the amount of copper associated with our ore. 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 coppe
