Activated carbon at the cyanide
Highly activated carbon is used in the dissolved gold recovery process, either by introducing it directly into the CIL (carboninleach) tanks or into separate CIP (carboninpulp) tanks after leaching. The activated carbon adsorbs the dissolved gold from the leach slurry thereby concentrating it onto a smaller mass of solids.

Carbon Adsorption In Recovery Of Gold From Cyanide Leach Solutions. It has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years, and many papers have been written on the subject. Carbon, as a media of recovery for gold from leach solutions, did not gain wide acceptance in the gold industry until ...
Activated carbon reduces fines formation and increases yield. A major use of activated carbon in mining is in gold recovery, where granular activated carbon (GAC) is used for adsorption of the goldcyanide complex in carboninpulp (CIP) and carboninleach (CIL) systems, or in carbonincolumn (CIC) systems after a heap leach operation carbon.
heated at elevated temperatures in the presence of steam to create activated carbon. In gold recovery applications, activated carbon manufactured by Thermal activation is used. This process will be discussed in more detail. There are a number of steps in the production of activated carbon…
CPL Activated Carbons has extensive operational and commercial experience in the supply of specialised grades of activated carbons into the precious metal recovery industry. Activated carbons are used to recover gold from cyanide solutions, which are percolated through goldcontaining ores.
For gold recovery circuits, it is essential that the activated carbon employed provides excellent process performance, minimal attrition loss and minimal maintenance problems. Significant improvements have been made in the still evolving carbonrelated technologies for gold recovery.
The adsorption of gold complexes onto the activated carbon is the basis of modern techniques for gold recovery. The next step is the recovery of adsorbed gold from activated carbon with an efficient eluant. The objective of this study was to investigate an improved process for recovering gold from activated carbon.
Highquality activated carbon is vital to the gold extraction operation. Using activated carbon of optimal hardness minimizes fines and recovers more gold.

Activated Carbon for Gold Recovery PJAC Gold “PJAC GOLD” is characterized by high gold adsorption capacity, high hardness characteristics, low abrasion loss and low platelet content. It is specially designed for gold recovery. PROPERTIES.
In the gold industry, there are three main methods for extraction of the metal, all of which use granular activated carbons in the recovery of gold from cyanide leachate solutions: – CarboninPulp (CIP) – CarboninLeach (CIL), includes ‘Heap Leach’ – CarboninColumn (CIL) Related Applications – Gold Recovery
Activated Carbon Essentially, the raw product defines the activated carbon product. The characteristics of the activated carbon product are thus dependent on raw material. A hard dense raw material results in a hard dense activated carbon with a micropore favouring structure. A soft, less dense raw material results in a soft light activated
