Precious Metal Recovery

In the field of precious metal recovery, activated carbon mainly extracts target metals from solutions or slurries containing gold, silver, palladium, and platinum through its excellent pore structure and physical/chemical adsorption capabilities. Customer focus: High adsorption capacity, fast kinetics, excellent wear resistance.

Activated carbon plays an important role in precious metal recycling.

Based on the type of ore or the nature of the waste, activated carbon application processes are mainly divided into the following types:

Carbon-in-Pulp (CIP): Gold is leached first, then activated carbon is used to adsorb gold from the ore slurry in a stirred tank. Customer focus: High hardness minimizes carbon loss during agitation.

Carbon-in-Leach (CIL): Leaching and adsorption occur simultaneously, effectively treating complex ores containing naturally adsorbed components. Customer focus: Fast adsorption rate, high gold loading capacity.

Carbon-in-Column (CIC): The gold-bearing solution is passed through a vertical column filled with activated carbon; commonly used to treat clear solutions or solutions from lean ore. Customer focus: Uniform particle size ensures consistent flow, low pressure drop.
