Activated Carbon for Gold Recovery

Activated carbon has long been used as an adsorbent in the gold processing industry to recover gold from mining operations. Due to its high surface area and exceptional hardness, coconut shell GAC (granulated activated carbon) is the main product used in carbon-in-leach (CIL), carbon-in-pulp (CIP), and carbon-in-column (CIC) operating systems.

Carbon regeneration

Outotec''s carbon regeneration systems utilize thermal regeneration technology. Some industries call the product "AC" for activated carbon. The process uses an indirect fired kiln to heat the activated carbon to 700°C, driving off the organic and inorganic contaminants. The system uses a recycle duct to improve energy efficiency.

carbon in pulp process in gold recovery ppt

A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.

Activated Carbon in Gold Cyanidation

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. Here too, activated carbon is the catalyst for recovery of this precious metal.
