what is the environmental impacts of mining chalcopyrite

  • Toward a more sustainable mining future with

    Metals are currently almost exclusively extracted from their ore via physical excavation. This energy-intensive process dictates that metal mining remains among the foremost CO2 emitters and mine waste is the single largest waste form by mass. We propose a new approach electrokinetic in situ leaching (EK-ISL) and demonstrate its applicability for a Cu-bearing sulfidic porphyry ore.
