Gravity-Based Separation
Gravity based separation relies upon the gravity of the materials and the relative movements concerning the gravity. Besides gravity, the viscous forces exerted by the liquids are used to treat and as a separation medium. Using the heavy liquids, such as tetraboromethane, the segregation, is eased from the plastics and ceramics.
