Occasionally, carbon columns will be used with tank leaching operations, also, especially if the mine has a dual leach system, heap leach of low grade and tank leach of high grade. Carbon columns consist of large columns (5 to 8 ft diameter) and 15 to 20 feet in height, charged with activated carbon.
The adsorption tanks are typically a quarter to a tenth of the size of the leach tanks. The CIL and CIP modes of operations occur in a number of tanks placed in series. Pulp flows continuously from the first tank to the last, while carbon is pumped counter current from the last tank to the first.

The APT TriTank is available as a small scale CIP/CIL cyanidation plant. The TriTank takes on a whole new revolutionary design making for a more environmentally conscious and even better way of using cyanidation as a gold extraction process, even at such a small scale. The design has multiple benefi

Carbon in Leach Circuit Carbon-in-Leach Circuit (CIL) For over a hundred years, miners have used dilute alkaline cyanide solutions (e.g., sodium cyanide [NaCN] around pH 10-11) to leach (dissolve) gold and other precious metals, from their ores. The gold is usually in …
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.

Yes I think the stage addition the possible option to reduce the cyanide consumption close to the limit. In the process of running cyanide optimization we have reduced from 190 to 165 ppm without identified any gold recovery reduction (baselines daily leach profile on solid, solution and carbon on each leach tank).
In leach tanks, where complete pulp and gas distribution are necessary to dissolve gold into solution, the A310 & A510 delivers the high mixing intensity needed for the job. In absorption tanks, too much shear degrades the carbon to a point where it passes through the screens, with the gold attached.
CPT SlamJet Oxygen Sparging Improves Gold Leaching . The dissolution of gold through cyanidation, either Carbon in Pulp (CIP) or Carbon in Leach (CIL), is an oxidizing reaction. Generally added oxygen, in the form of dissolved oxygen in solution, improves the process as the rate of gold
The two chemicals that carbon excels at pulling from tanks are phenols and tannins. These are produced from a variety of sources, including the metabolic waste of fish, leaching from wood, the breakdown and decomposition of faeces, plants and uneaten food, and more.
Leaching reagents in the form of cyanide and oxidant such as air or oxygen are added after thickening. Leaching take place in a series of agitated leaching tanks/slots. 4 Carbon adsorption. Before leaching, the pulp is passed through a linear vibrating screen to ensure removal of trash materials.
Air is added to increase the reaction rate and shorten the leach time. Cyanide is added, typically in the first tank. Each carbon leach tank has a interstage screen in it for carbon retention. Slurry can gravity flow between tanks or be pumped. Typically there are 4 to 6 tanks in series.
Leached pulp and carbon are transferred in a counter current flow arrangement between a series of tanks, usually numbering 4 to 6. In the final tank, fresh or barren carbon is put in contact with low grade or tailings solution. At this tank the fresh carbon has a high activity and can remove trace amounts of gold (to levels below 0.01 mg/L Au in solution).
However the preparation of a gold production report is often complicated by the large inventory of gold in the carbon in pulp (CIP) or carbon in leach (CIL) tanks used to adsorb leached gold from the solution.
Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes have surface areas of about 1000 m²/g i.e. one gram of activated carbon (the amount of which will occupy the same space as the end of a person's thumb) has the same surface area as two football fields.

CHAPTER 3. ACTIVATED CARBON COLUMNS PLANT DESIGN 112 applications. The principle limitation is related with the pressure drop. It was checked that it was not too high, so the final choice was FILTRASORB 400 .
A process very similar to carbon-in-pulp. In the carbon-in-leach process, the leaching and absorbing of gold onto carbon take place in the same tank
conventional CIL circuits, leaching takes place in the presence of carbon and therefore leaching and adsorption occur simultaneously. The CIL circuit at SDGM can be considered a hybrid circuit as the first tank of each train are purely leaching tanks (no carbon addition). CIL Tank Train No. 1

In Carbon-in-Pulp and Carbon-in-Leach cyanidation methods, primary leaching takes place in a series of tanks. Finely ground gold ore is slurried with the leaching solution.
The leaching and carbon adsorption kinetic data are then fitted to the rate and mass balance equations. The model then generates profiles of gold in solution, on the carbon and in the leach residue across a series of leaching and adsorption tanks in which carbon is advanced counter-current to the flow of slurry. SGS metallurgists can then optimize
