plant, soluble copper became a much more important issue at Gedabek. Grinding the ore to minus 75 µm for agitation leaching, instead of crushing it to minus 25 mm for heap leaching, exposed much more of the copper minerals to direct contact with the cyanide leach solutions, which increased the rate and extent of dissolution of copper. Furthermore, as the mine went deeper, the copper grades of ...
