    02/01/2013· Likewise, the benefits of the carboninleach (CIL) process compared with leaching and carboninpulp (CIP) have been clearly demonstrated both experimentally and in practice, even without the presence of interfering pregrobbing constituents in the ore The CIL process results in improved conditions for gold dissolution as a result of the lower gold tenor, albeit at a cost of lower gold12/05/2020· The carboninleach process integrates leaching and carboninpulp into a single unit process operation in which the leach tanks are fitted with carbon retention screens and the carboninpulp tanks are eliminated The activated carbon is added in leach, with gold adsorption occurring nearly simultaneously with goldCarbonInLeach Jacobi GroupGold Recovery Process For gold recovery, water and a cyanide such as calcium cyanide, sodium cyanide, or potassium cyanide, are added to ore or scraps to form a slurry The gold will leach out and mix with the cyanide into a solution Activated carbon is then used to separate and store the gold, which is removed as the final step of the processActivated Carbon for Gold Recovery Puragen
