magmatic iron deposit



  • Nickel Deposits Explained | Balmoral Resources Ltd

    Thus magmatic sulphide grains are typically multi-phase being comprised of separate chalcopyrite (copper-rich), pyrrhotite (iron-rich) and pentlandite (nickel-rich) phas A number of open pit nickel deposits are developed within these disseminated zones which tend to be more laterally extensive than the massive sulphide zon
