GOLD RECOVERY

For many years now, activated carbon has been used in CIP. CIC, and CIL processes for the recovery of gold, and other precious metals.

In such processes, the hardness, and abrasion resistance of the carbon is essential to avoid gold losses through breakdown of the carbon within the circuit.

Due to this, coconut shell based carbon is predominantly used in this type of process. The natural hardness of the raw material, coupled with specially developed manufacturing techniques, facilitate an end product ideally suited to this application.

Product Description IKAGOLD

Ikagold 612 and 816 are two high activity coconut shell Activated Carbons, with a highly microporous. structure, specially developed for use in the application of gold recovery from aqueous cyanide solutions in CIR CIC, and CIL circuits.

Their high abrasion resistance renders these product particularly suitable for carbon-in-pulp (CIP) applications.
