Gold Adsorption Activated Carbon Suppliers & Manufacturers

Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution. The CIL process is frequently used when native carbon is present in the gold ore. This native carbon will absorb the leached gold and prevent its recovery. This phenomenon is referred to commonly as "preg-robbing".
