Gold CIL CIP Gold Leaching Process Explained CCD

2013-1-2  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 (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold

Gold Extraction, Gold Cyanide, Gold Manufacturing

[Introduction]: Gold CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore. 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.
