The beneficiation of iron ore in the size range of -32 +0.2 mm is well established globally. Dense medium separation (DMS) and gravity concentration are the beneficiation processes used. Iron ore production in this size range is almost exclusively based on haematite. Table I provides a summary of the processes commonly used for various size ...

The size of a particle influences its action in the separator as the charge on the surface of a coarse particle is lower in relation to its mass than for a fine particle. As a result of this coarse particles are more easily thrown from the rotor surface. Particle sizes for beach sands range from 50 to 1000 microns (0.05 to 1.0 mm),
