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 low-grade copper ore.
