CIP process is a high efficient method to leaching and recovering gold from gold ore, The most different from CIL process is in CIP process, gold leaching and adsorption are separated, first leaching, and then adsorption. Now it is being replacing by CIL process progressively. But it still have a lot of application.
Gold CIL processing plant Carbon in Leach process is widely used in the mining industry and in particular, it is an integral step of gold processing in gold extraction. Normally the CIL process can concentrate gold from 2.53.5 g/t in ore to 2000 to 6000 g/t on carbon.
Haycarb has been a pioneering supplier of activated carbon for Carbon in Pulp , Carbon in leach and Carbon in circuit processes in gold mining since the 1970s. Recognizing the critical role activated carbon plays in a gold mining process, Haycarb Gold Activated Carbon series present a range of coconut shell based re generable products for CIP/CIL /CIC extraction process boasting high hardness values and resistance to abrasion.
In the absorption stage, this solution flows through several agitated tanks containing activated carbon. Gold absorbs onto the activated carbon, which flows countercurrent to the pulp, while screens separate the barren pulp from the gold loaded carbon. Carbon in leach 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.
The gold CIL process in the CIL plant mainly includes the preparation of leaching material, agitation leaching and countercurrent carbon absorption, gold bearing carbon desorption, electric electrolytic desorption, smelting tableting, carbon regeneration and other operations.

Carbon pulp extraction process 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, gold loaded carbon desorption, electrowinning electrolysis, smelting ingots, carbon regeneration.
Gold CIL production line Process Introduction. CIL process is the most efficient method to leaching and recovering gold from gold ore, The most protruding features is that leaching and adsorption are carried out at the same time, which greatly saves the cost of construction and operation.
By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lowers the gold mining operation cost and increases gold recovery rate to 99%, which is the first choice of modern gold mining and gold beneficiation plant.
