High-quality activated carbon is vital to the gold extraction operation. Using activated carbon of optimal hardness minimizes fines and recovers more gold. By maximizing the efficiency of your gold recovery process, Carbon Activated products and services help maintain your bottom line. Use the best carbon for the best recovery.
Highly activated carbon is used in the dissolved gold recovery process, either by introducing it directly into the CIL (carbon-in-leach) tanks or into separate CIP (carbon-in-pulp) tanks after leaching. The activated carbon adsorbs the dissolved gold from the leach slurry thereby concentrating it onto a smaller mass of solids.
From the contact tanks the loaded activated carbon is transferred to the elution and regeneration phase. The now barren carbon is returned to the contacting phase where any losses are made up with activated carbon. The gold is then recovered by a process known as electrowinning.
We aim to be the world class leader in the manufacturing and marketing of activated carbon solutions that are purely derived from coconut shell. We envisage to produce activated carbon for water treatment applications, energy storage applications, air purification applications, chemical, beverages, Gold recovery and more.
