Authors Grace Ofori-Sarpong,Carbon-In-Leach | Jacobi Carbons,The activated carbon is added in leach, with gold adsorption occurring nearly simultaneously with gold dissolution by the cyanide solution. This method is often employed when native carbon (as organics) is present in the gold ore and adsorbs the leached gold, preventing its recovery. The activated carbon used in the carbon-in-leach circuit preferentially adsorbs the gold over the native carbon and allows the goldCarbon-in-Leach Gold Recovery from Fungi-treated,,72 Grace Ofori-Sarpong et al.: Carbon-in-Leach Gold Recovery from Fungi-treated Carbonaceous Ore: Effect of Entrained Biomass on Activity of Activated Carbon which it is conditioned appropriately and fed into the Carbon-In-Leach (CIL) circuit, where leaching of gold and adsorption of gold ions onto activated carbon (AC) are done simultaneously.
