Calgon Carbon's activated carbon products for gold recovery provide our customers with exceptional value by maximizing yield and minimizing loss. Activated carbon is a highly porous organic material comprised of a series of graphitic plates, which are interconnected by carboncarbon bonds.
We offer and recommend our gold recovery training at our USA facility, for no additional cost, when purchasing our gold mining equipment. Large Scale Proven From the Yukon through the Rocky Mountains and into the Jungles, we have designed and manufactured equipment plants / systems processing 1,500+ tons of ore per hour.
straight forward and achieves high gold recovery. The higher the gold to sulphur ratio the better in terms of downstream processing options. For refractory gold ores gravity recovery is usually poor and of little benefit. "The processing options for the concentrate represent the greatest challenge technically. The

DG can be effectively reused in the gold recovery process after it has been reactivation. This helps to reduce operating costs associated with carbon makeup. After stripping gold by elution, the carbon's capacity for gold can be restored by thermal reactivated at temperatures in the range of 1100 1400°F.
