Gravity separation relies on differences in material mass to separate minerals. 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 since volume is proportional to weight.
