In the CIP process, activated carbon is used to adsorb the gold directly from the cyanided pulp in a series of large adsorption tanks. Pulp flows continually from the first vessel to the last in the series, and the carbon is transferred intermittently by pumping in the opposite direction.

Leaching & Adsorption Resource Book

The dissolved gold in solution is adsorbed onto activated carbon. When the carbon is loaded with enough gold it is removed from the circuit and sent to elution where the adsorption process is reversed and the gold is stripped off the carbon back into solution, electrowon and smelted into bars.

The control and optimization of carbon-in-pulp and carbon-in-leach plants has been the subject of much research and development. As a result of many years' experience in the study of the processes taking part in the leaching of gold and the absorption of gold on to activated carbon, the present version of SIMCIL has evolved as a most effective

Gold CIL & CIP Gold Leaching Process Explained CCD

Metallurgical ContentLearn CyanidationDevelopments in the Carbon-In-Pulp ProcessDesign Criteria Commercial Operations Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon.

AURODICYANIDE DESORPTION FROM ACTIVATED CARBON

carbon is most often used to adsorb gold from dilute alkaline cyanide solutions. The gold is dissolved as the Au(CN) 2-complex and is recovered from the solution by Carbon-in-Pulp (CIP) or Carbon-in-Leach (CIL) processes. Activated carbon loaded with gold must be treated by an elution step to desorb the gold for subsequent recovery.

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.
