    Copper Production Amp Environmental Impact

    Copper production amp environmental impact.Extraction and Beneficiation Wastes and Materials Waste Rock. Waste rock is typically hauled from the mine site to waste dumps for disposal. Waste rock piles may have high permeability to both air and water. Oxygen and sulfide minerals may be contained in the dump. The quantity and composition of waste rock generated at mines vary greatly by site.
