Kelin Carbon in Column for Gold Recovery

Carbon-in-Column (CIC) Plants are one of the most common and proven engineering solutions for processing solution from heap leach pads. They consist of large-diameter columns that are filled with activated carbon. The pregnant solution flows through the carbon columns, generally in a step-down arrangement so that the overflow from the highest elevation column will flow to the next column. The gold absorbs onto the surface of the carbon. The loaded carbon is periodically removed from the columns and sent for stripping.

With carbon-in-column operation, the gold cyanide solution flows through a series of fluidised bed columns in an up-flow configuration. Fluidised bed carbon columns can process solutions that contain as much as 2 to 3 wt% solids, thus making them well suited for heap leach applications which are often high in solids content.

Kelin activated carbon is designed for gold recovery processes and is used by gold plants all over the world. Our products provide excellent adsorption and elution characteristics, show outstanding hardness and high resistance to attrition. In addition, the strictest platelets control is used in order to minimise carbon fines generation in circuit and during regeneration. Less carbon fines in the circuit means less gold lost to the tailings!

 Kelin has a few-decade history of supplying activated carbons to leading gold producers. Therefore, if you have any question in carbon for gold recovery, please fell free to contact us.
