    Gold CIP, CIL System, Heap Leaching, Cyanidation

    Carbon leaching process is characterized by simultaneous gold leaching and adsorption stages, with normal leaching segments of 6-10 segments. In the leaching process, ensure the fineness of grinding products - 200 mesh accounted for 85-95, the pulp concentration accounts for 40-45, then add a certain volume of ExAurum ECO gold leaching agent.

    2020-6-18Heap leaching can take anything from a couple of months to several years. In the case of gold recovery, heap leaching generally requires 60 to 90 days to leach the ore, compared to the 24 hours required by a conventional agitated leach process. Gold recovery is also usually only 70 compared with 90 recovery in an agitated leach plant.

    CYANIDE IN PROCESS SOLUTIONS Typically for gold leaching, sodium cyanide is added to the barren solution to maintain a concentration of about 0.5 pound per ton of solution. This equates to about 250 ppm. The protective alkalinity is maintained in the barren solution pond by the addition of lime, and a pH between 9 and 11 is maintained.
