  • Dry Magnetic Separation of Bauxite Ore

    Dry Magnetic Separation Of Bauxite Ore

    Bauxite is the principal source of aluminium. About 90 of the bauxite mind are utilised for the metal extraction while the rest is consumed in the chemical, refractory, abrasion etc. The refractory grade bauxite finds wide application as primary feed stock for the 60 to 90 alumina content category of refractory shapes and specialities.
