The methods are Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Pumpcell technology. CIL and CIP are typically counter current operations while the Pumpcell technology makes use of the carousel mode of operation. The CIL mode of operation is when the leach and adsorption circuit are combined into a single process.

The optimisation of carbon management is essential for minimising soluble gold losses in carbon-in-leach (CIL) and carbon-in-pulp (CIP) circuits. Carbon inventory, ie knowing the carbon concentration in each reactor, is crucial for good carbon management. Currently, carbon concentrations are mainly determined from small samples that are taken …

The Carbon Scout is a self-contained, ground-level sampling system that measures the pH, dissolved oxygen (DO), density and gold concentration in carbon-in-leach (CIL) and carbon-in-pulp (CIP) circuits. An important new feature is an optional X-ray fluorescence (XRF) to measure gold on carbon for real time gold circuit inventory.

A disadvantage that follows the increasing concentration of carbon in slurry is the high amount of carbon fines. The amount of fines formed in the process is proportional to the carbon present in the system. With 8 kg/m3 of carbon, the loss of carbon fines is 3.09 kg/h, which escalates to approximately 15 kg/h for 40 kg/m3 of carbon.

stirred tanks. Freshly activated carbon, with a much larger particle size than the ore, is introduced into the final tank. Typically the carbon is retained in any tank by suitable screens and is intermittently progressed up the bank by some type of gentle pumping system and is finally removed from the slurry for desorption of the values.
