Carbon is an essential element for all life forms on Earth. Whether these life forms take in carbon to help manufacture food or release carbon as part of respiration, the intake and output of carbon is a component of all plant and animal life. Carbon is in a constant state of movement from place to place. It is stored in what are known as reservoirs, and it moves …

Gold cyanidation is an established gold extraction process worldwide and carbon-in-leach (CIL), as an affiliate process, is the subject of extensive research and model development work. Most of the CIL process modelling efforts have focused on steady state scenarios for process design considerations. In this multiphase, counter-current process, however, steady state conditions …
Comsur's Comco silver heap leach at Potosi, Bolivia, showed the same recovery in both a heap and an agitated leach plant. However, the silver ore leached very slowly and residence time of up to 4 days was needed in an agitated leach plant. Although the heap leach took several months to achieve the same recovery, the economics favored the heap.
In the CIL (Carbon in Leach) or CIP (Carbon in Pulp) plants while the precious metals are being dissolved by the cyanide solution in the large volume tanks the dissolved metals are adsorbed by the active carbon. These processes are generally preferred for the relatively high grade and lower reserve ore types with very fine graded precious metals.

Carbon pulp extraction process (CIP method and CIL method) is to put activated carbon into the cyanidation pulp, and the dissolved gold is adsorbed on the activated carbon, then the gold is extracted from the activated carbon.This process mainly includes the following steps: the preparation of leaching materials, agitation leaching and countercurrent carbon adsorption, …
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.

Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are
O ne of the advantages of heap leaching versus conventional milling and using either carbon-in-pulp (CIP) or carbon-in-leach (CIL) for gold recovery is the lower cost. However, along with that lower cost comes a lower recovery rate. Gold recovery is also usually only about 55% to 75% compared with roughly 90% recovery in an agitated leach plant.

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.
Carbon in leach (CIL) is an important process in gold processing involving simultaneous leaching and adsorption. The process holds the key to profitability in gold extraction.
carbon-in-leach (CIL) or carbon-in-pulp (CIP) tests using standard procedures (Angove, 2005). The key question is whether the standard laboratory test work procedures developed historically for low reagent-consuming ores are appropriate for ores that are high cyanide and oxygen consumers. The present paper examines test procedural factors that can
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. CIL stands for carbon-in-leach. This is a gold extraction process …
