gravity separation

gravity separation

[′grav·əd·ē ‚sep·ə′rā·shən]
(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.
