Application Detail

Gold Recovery

Microporous coconut shell carbon grades for CIP, CIC, and tank-adsorbed precious-metal recovery systems.

Application overview

Gold recovery is a specialist performance application where hardness, low platelets, low dust, and adsorption kinetics directly affect metal loading and carbon loss.

GC grades are highly microporous, high-hardness, and built with excellent attrition resistance.

The product range emphasizes very low platelet content, zero dust, and vee-wire screening to keep fines to a minimum.

Black Opal positions itself as a supplier to some of the world’s largest mining companies.

Recovery systems

GC grades are built for Carbon-in-Pulp, Carbon-in-Column, and tank-adsorbed systems where adsorption of metal and cyanide complexes has to happen quickly and cleanly.

Why the carbon is tuned this way

The particle size and pore structure are engineered for precious-metal adsorption while maintaining the hardness needed to resist attrition in mining circuits.

Operating advantages

Buyers specify these grades for durability, adsorption performance, and clean operation in recovery circuits.

Superior hardness to minimize attrition loss and dust

Higher gold adsorption capacities for maximum loading

Excellent gold adsorption rates for high throughput
