This process is very similar to the CIP process The main differences lie in the preparation of the slurry and method for removing the gold from the leachate In a CIL process the carbon is mixed with the leachate solution not with pulp This is a much less abrasive system meaning that the carbon lasts much longer than in a CIP process
