Improving the recovery of gold and copper in a CIP .

The copper-free loaded carbon was easily treated for gold with very high elution and electrowinning efficiencies of 96 and 98% respectively. A bullion of high fineness (in the region of 98% gold and silver) was obtained and the activity of carbon after elution was reasonably high at 8 0% of carbon.
