CIL (Carbon In Leach), the gold carbon leaching method, is the carbon leaching method for gold extraction.Normally, the CIL process can concentrate gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t in carbon. The CIL gold process is suitable for beneficiating oxidized gold ore with low sulfur and mud content; Or process the gold tailings after gravity separation and mercury mixing.

To further evaluate the process of Gold Recovery by Gravity, Flotation and Carbon-in-Leach Cyanidation, some cleaner tests with regrind of the bulk rougher concentrate, were conducted. Rougher flotation concentrates were reground to improve leach kinetics. The regrind sizes for these range of tests were not optimized.

The Ity Gold Mine in Côte d'Ivoire has been in operation for more than 20-years, previously as a heap leach operation. Recent construction of a carbon-in-leach plant has allowed for an …
In a CIP plant, leaching is complete before the first adsorption tank, and gold is then recovered from the leached pulp in a series of (typically) 4–10 dedicated carbon adsorption tanks. In a CIL plant, the carbon is added directly into the leach tanks, with the claimed advantage of lowering capital costs by eliminating the CIP adsorption tanks.
CIL (Carbon in Leach) is a widely used method for extracting gold from ore. It is a metallurgical process that involves the dissolution of gold particles into a cyanide solution and …

the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank. This paper presents a dynamic model that describes, with minor
recovered from solution by either zinc precipitation, adsorption onto activated carbon or by the use of ion exchange resins. The most popular of these recovery methods is the adsorption of gold onto activated carbon, which is used in carbon-in-pulp (CIP) circuits. Many CIP and carbon-in-leach (CIL) plants have been
ENGLISH SUMMARY: Carbon-in-pulp (CIP) and carbon-in-leach (CIL) circuits have been the primary methods used for treating gold ores for many years. Although inherently robust processes, there is still often much room for optimisation to improve gold extraction efficiencies and to reduce reagent consumption and operating costs. A number of models for leaching and …
Although the era of CIP commenced in the late 1970s, the use of carbon for the recovery of gold was recognized and practiced much earlier. Davis (1880) patented the use of wood charcoal for gold recovery from chlorination leach liquors, with this process subsequently used at Mount Morgan, Australia in the early 1890s. Johnson (1894) patented the use of wood …
The Company envisions staged open pit mining of satellite deposits and processing in a currently operating carbon-in-leach plant.
Carbon-in leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon.
