Gravity Separation an overview ScienceDirect Topics

The separation by gravity is based on the difference in settling rates or terminal velocities of particles of different density and size. However, with short distances of travel in some separation processes, particles may not have a chance to reach their terminal velocity.mineral processing Concentration Britannica,Gravity separation Gravity methods use the difference in the density of minerals as the concentrating agent. In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon).
