Carbon and Resin Technologies for Gold Recovery Mining SGS

Carbon-in-leach 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

Carbon in pulp Wikipedia

Leached pulp and carbon are transferred in a counter current flow arrangement between a series of tanks, usually numbering 4 to 6. In the final tank, fresh or barren carbon is put in contact with low grade or tailings solution. At this tank the fresh carbon has a high activity and can remove trace amounts of gold (to levels below 0.01 mg/L Au in solution).
