Gold CIL CIP Gold Leaching Process Explained CCD

2013-1-2  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 ores that contain preg-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.

Gold ore Carbon-In-Leaching (CIL) processing

2018-11-12  The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the so-called Carbon-In-Leach process (CIL). The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated out onto cathodes of steel wool. The loaded

Activated Carbon in Gold Cyanidation

Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.
