Gold CIL CIP Gold Leaching Process Explained CCD

02/01/2013  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

followed by secondary ball milling. After comminution the pulp is normally dilute and thickening (6-12% solids by mass) is performed to increase the pulp density to about 50% solids by mass. This reduces the size of the leaching plant that would be required as well as reduces the amount of leaching reagents required. Many gold plants use conventional thickening with flocculant addition. High ...
