    Cil -cip) On Gold Processing )


    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.
    The Lightnin laser designed A310 & A510 impellers are unsurpassed for applications where high mixing intensity and low shear are required, making it an ideal choice for CIP/CIL applications. In leach tanks, where complete pulp and gas distribution are necessary to dissolve gold into solution, the A310 & A510 delivers the high mixing intensity needed for the job. In absorption tanks, too much shear degrades the carbon to a point where it passes through the screens, with the gold attached. For a given tip speed, the A310 & A510 generates the least shear of any high efficiency impeller, resulting in lower carbon abrasion and greater gold recovery.
