Gravity separation and Ore Beneficiation IspatGuru

Oct 12, 2018 Fig 1 Effect of centrifugal force on gravity force. Separation of the ore particle by gravity is dependent on two factors namely (i) settling rate of the particles, and (ii) difference in specific gravity when compared against the medium in which they are being separated, this gives differential settling rate and has been termed the ‘concentration criteria’.Settling rate of a particle is

Iron Ore Mineral Technologies

Hard rock hematite deposits often require a combination of milling, screening and on occasion, fine classification to prepare a finely sized (-1.0mm), liberated feed for beneficiation by gravity separation. This is typically followed by re-grinding of the tailings to liberate more hematite for further iron unit recovery by magnetic separation.
