Molybdenum Concentrate Process

  • Recovery of molybdenum concentrate . - molybdenum-sheet

    Recovery of molybdenum concentrate . - molybdenum-sheet

    Recovery of molybdenum concentrate from tailings by a new process. The iron concentrate was obtained by using the first magnetic flotation sequence for iron and molybdenum type ore. The magnetic separation tailings are floated by the process of "one coarse, two fine, two sweep coarse concentrate regrinding and cleaning four times" to realize the effective separation of molybdenum from other .
