Gold CIL & CIP Gold Leaching Process Explained CCD

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ... Gold …

Lime use in gold processing – A review

The front-end flow sheet configuration for gold ores with nuisance copper is typically the same as illustrated in Fig. 5. Gravity gold is also often extracted, although the presence of native copper may also cause complications. Gold ores with nuisance copper differ from free-milling oxide ores in the back-end treatment of the cyanide-leached ...
