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.

Carbon In Column

Jacobi offers a full range of carbon products to serve the gold recovery industry. This includes standard granular activated carbon grades (GoldSorb™ 4500 and PICAGOLD™ G208AS), higher capacity granular activated carbon grades (GoldSorb™ 5500 and PICAGOLD™ G209AS), and highest premium activity granular activated carbon grades (PICAGOLD™ G210AS and PICAGOLD™ G210 Ultima).


Goldsorb / Picasorb


The undisputed industry leading brand, our PICAGOLD™ and GoldSorb™ range of activated carbons, 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!
