Carbon in leach process

Definition of carbon-in-leach process. A process step wherein granular activated carbon particles much larger than the ground ore particles are introduced into the ore pulp. Cyanide leaching and precious metals adsorption onto the activated carbon occur simultaneously

    This batch model was extended to a continuous model that simulated three leaching and seven carbon-in-leach tanks. The effect of processing the oxide and sulphide ores studied was examined and the model shown to satisfactorily describe the extraction of gold from the Telfer oxide ore. A sensitivity analysis of the effect of process changes

    3. Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution

    Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously

    Here the carbon is washed with dilute hydrochloric acid to remove for instance soluble salts. The carbon is further rinsed with water to remove the acid before it is soaked with a caustic sodium cyanide solution at elevated temperature. A number of bed volumes of hot water are then pumped through the bed of carbon to eluate the gold
