Products Description
Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. In the absorption stage, this solution flows through several agitated tanks containing activated carbon. Gold absorbs onto the activated carbon, which flows countercurrent to the pulp, while screens separate the barren pulp from the gold-loaded carbon.
Carbon-in leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon.These reduce the gold yield by attracting gold meant for the activated carbon. Simultaneous leaching and absorption help minimize the problem.

Process description
Crushing ModuleThe rocks are crushed to the qualified particle size for grinding. The module is composed of hoppers, crushers, belt conveyors,feeders and so on.The ores are usually crushed in two stages. According to the actual situation of the site, the primary crusher can be mounted in the mining area or the processing plant. The crusher is usually driven by a diesel engine if it is located in the mining area.
thickening SyetemAfter ball mill grinding, the ore pulp will be feed into thickner to dewater to achieve proper density to go next step leaching. Under the thickner, there is enough space to build several warehouse and install a chemical mix tank.
Leaching SystemAfter the ore pulp adding cyanide, it will be pumped to leaching tank, usually we adopts 8 leaching tanks, installed in
stair-stepping, the toppest two is preleaching tank, will add actived carbon from lowest one, then use carbon lifting pump and carbon screen to lift the gold carried carbon one by one till highest. After leaching, gold mud in grade about 30-40% will feed into electrolysis machine or melting furnace to separate gold and carbon, after this step, the carbon can be recycled by acid and water washing tank. At last the gold grade will be at 98% above.
