It is the first process that most ores undergo after mining in order to provide a more to produce the richest possible concentrate at the lowest possible operating cost. . density gravity separation, magnetic or electric magnetic and electrostatic Gravity concentration on inclined planes is carried out on shaking tables,
Particle size plays an important role in mining and mineral separation. Methods include jigs, sluices, spirals, shaking tables, fine particle separators, and hydrosizers and cyclones. Gravity separation is separation based on weight only and is directly affected by particle size Sieves have a long history and low initial cost.
