    Producing Copper Nature's Way: Bioleaching

    The GEOCOAT™ Process A heap leaching process that is capable of bioleaching copper concentrates. It does this by coating the concentrate slurry onto a support rock, or substrate material, and stacking this coated material in a bioxidation heap. The support rock itself may be a lowgrade copper ore. The ratio of support rock to concentrate is in the range of 5:1 to 10:1 by weight. The heap
