Gold CIL & CIP Gold Leaching Process Explained CCD

Mar 17, 2017 ... 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...

Jan 18, 2004 ... Because of the potential value of by-product copper, earlier flowsheets used carbon-in-leach for SAPO, but processed all other ore types by flotation to produce a gold-copper concentrate with cyanide leaching of cleaner tailings to maximize gold recovery. Cyanide recovery was necessitated by the high...

Donau Carbon world-wide - Activated Carbon

There are several gold processing operations requiring activated carbons: CIP (Carbon in Pulp): gold pulp is mixed with sodium cyanide, then is contacted with activated carbon in a serie of large agitated adsorption tanks. CIL (Carbon in Leach): similar to CIP but leaching and adsorption occur simultaneously. CIC (Carbon...
