  • ore dressing copper process leaching

    Heap Leaching Oxide and Sulfide Copper Ores. In the heap leaching method, crushed or uncrushed oxidized copper ore is placed on a prepared drainage pad. Acid leach solutions are distributed over the top of the heap, caused to percolate downward through the ore bed by gravity, and are drained from its base.
