GoldSorb 4500Â
GoldSorb® 4500 is a medium activity granular activated carbon manufactured by steam activation from carefully selected coconut shell charcoal. It is ideally suited for the recovery of precious metals in all forms of contactors providing good adsorption and elution characteristics. GoldSorb® 4500 exhibits maximum product hardness and this results in a high resistance to attrition contributing to lower gold losses in the circuit. Furthermore, during regeneration, GoldSorb® 4500 produces fewer fines which require disposal and ensures a minimal requirement for make-up carbon from inventory stock.
