  • Magnetite Ore Mining Solution Mineral Processing

    For dry and water-scarce areas, the magnetite ore dressing plant may consider using dry grinding-dry magnetic separation process; For the depleted magnetite-rich ore or magnetite-rich ore, the gangue can generally be removed by dry magnetic separation process, and then the lump-rich ore is obtained, and then the concentrate is obtained through the grinding-magnetic separation process.

    Flotation has been commercially used as a method for removing pyrrhotite from magnetite for high sulfurous iron ores [4]. In this process, pyrrhotite as a primary impurity is separated from iron ore using typically potassium butyl xanthate as the primary collector. The flotation process normally

  • Coal Washing, Magnetic Separation & Processing

    In comparison magnetite ore has lower iron content when mined of between 25% and 40% Fe and requires processing, or magnetic separation, to separate magnetic minerals from other minerals in the ore. The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3O4) which when processed produces a magnetite concentrate with a magnetic content in excess of 96% magnetics.
