Gravity separation

gravity separation. [′gravədē ‚sepə′rāshən] (engineering) Separation of immiscible phases (gas-solid, liquid-solid, liquid-liquid, solid-solid) by allowing the denser phase to settle out under the influence of gravity; used in ore dressing and various industrial chemical processes.

Gravity Separation

The Kelsey Centrifugal Jig (KCJ) operates at up to 40 times gravitation acceleration in order to extend the separation range of gravity separation down to less than 40 μm. The Kelsey Centrifugal Jig utilizes the Harz design which is divided into two parts, the top section of heavy mineral (ragging) above a screen, and the jig chamber filled with water and pulsed by a diaphragm plunger.

Gravity Separation

Gravity separation uses differences in specific gravity (SG) between various minerals to achieve a separation, and is normally a wet process although examples of dry gravity separators exist. Gravity separation works best when there is a large difference in the SG in the minerals to be separated, and the particle size is similar and not excessively fine, and shape is rounded.

FL gravity density separators for minerals

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.
