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.

The Gravity Separation Mixture Fluid: An Innovative …
Gravimetric separation is one of the most popular separation techniques. In fact, it exploits the use of gravity, everywhere present on Earth without the aid of external actions, which makes the process extremely economical. However, it can generally require high retention times of the mixture inside the devices to make the separation effective.
