Gravity separation is a method in which materials/minerals are separated based upon the difference in particles density [1]. Water as a medium is an important factor in improving the differential movement between various particles during gravity separation and eventually sorting different particles [2]. When water is removed, and air plays the

· Gravity Concentration. Gravity concentration is the process in which separation is realized by using the differences in density of mineral particles in a certain medium or medium flow (mostly water). It is mostly used for separation of the ore in which the useful mineral has major density difference from the gangue, e.g., tungsten ore, tin
