In leaching, ore which has been ground to pulp is placed in agitated tanks with sodium cyanide solution and gold and silver is dissolved into the slurry solution. The leach may require 24 to 72 hours to complete, and after the leach is completed, the leached slurry is routed to the CIP circuit. In CIP, adsorption of gold and silver onto activated carbon is completed in agitated tanks with
