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

Leaching and recovery of gold from ore in cyanide

2020-11-1  The addition of 15 g/L of activated carbon to the pregnant leach solution (PLS) could provide 100% recovery of gold from solution onto activated carbon, i.e. holistic recovery of 90%. Presence of carbon in leach (CIL) resulted in slightly lower (95%) gold uptake from solution and significantly decreased the holistic gold recovery down to 77%.

Leaching and recovery of gold from ore in cyanide

2020-11-1  In the carbon-in-leach test (CIL-1), the observed gold recovery from solution onto activated carbon was 96%, while holistic recovery of gold remained only at 62%. However, in the longer carbon-in-leach test (36 h, CIL-2) holistic gold recovery of 77% was obtained, whereas the gold uptake from the loaded solution was at the same level (i.e. 95%).
