· Heap Leaching. Heap leaching is employed to dissolve copper from porous oxide ore that has been placed on a prepared surface. Heap leaching contrasts with dump leaching principally in that ore material is leached instead of waste material. This method is not applicable to the dissolution of copper sulfide minerals or to ores containing large amounts of carbonate or other acid soluble gangue ...
