How to Process Gold Ores by Heap Leaching & Carbon Adsorption Methods
Feb 18, 2021In typical continuous carbon-adsorption operation, the gold cyanide effluents from heap leaching are pumped upward through from three to five columns or tanks in series which contain granular activated carbon. The harder carbons, manufactured from coconut shells, are preferred for use because there is less tendency for breakage or abrasion.

Activated Carbon in Gold Cyanidation - FEECO International Inc.
The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation.
