Estimation of gold inventory in large carbon in leach tanks
2011year5month1day Approximately 50% of the total gold processed by the plant gold is dissolved and recovered onto the carbon. Each tank is charged with a target concentration of 15.0 g/L of carbon. Gold that dissolves from the ore is continuously adsorbed onto the activated carbon. The discharge of the last tank flows to the tailings ponds.
