flotation process molybdenum

  • Molybdenum processing . Britannica

    Apr 26, 2018 . Molybdenum and copper molybdenum porphyries are mined by open pit or by underground methods. Once the ore has been crushed and ground, the metallic minerals are then separated from gangue minerals (or the molybdenum and copper from each other) by flotation processes, using a wide variety of.
