Titanium Ore Processing and Beneficiation

Concentration in this typical case starts at about 10 mesh and continues on into the minus 200 mesh fines. Gravity concentration starting as coarse as possible is very important in the recovery of a mixed ore of rutile and ilmenite, for a granular slime free product is much more amenable to subsequent magnetic and electrostatic separation.

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 .
