Gold Ore CIL Processing Plant
One of the most widely used gold ore processing techniques is the carbon-in-leach (CIL) method. The CIL (Carbon in Leach) is a hydrometallurgical technique used to extract gold from ore. It involves leaching the gold from the ore using a cyanide solution, followed by adsorption of the dissolved gold onto activated carbon.
Leaching Low-Grade Gold Ores
Gold Ores A dilute cyanide solution is an efficient solvent of gold. However, as in any ot4er leaching process, the solvent has to come in contact with the solid gold particle. Hence, extensive crushing and meticulous two-stage, closed-circuit grinding are needed to liberate the gold particles in the ore.

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES
ore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG 19.3) and most gangue minerals (SG 2 to 3). For gold ores that are amenable to gravity separation, recovery of the coarse,
