After 12 h of leaching, 20–30 kg of activated carbon/tonne of material is added to the tanks, where the carbon contacts the cyanide solution for an additional 12 h. When no gold is detected in the solution, miners open a valve to drain the pulp on a 2 mm rotating screen to retain the activated carbon.
