CHAPTER-7 GRAVITY CONCENTRATION OF IRON ORE R. K. Rath, R. Singh Published 2012 Geology, Materials Science Gravity concentration process is the oldest beneficiation method known to mankind. This is a physical process and exploits the differences in densities of minerals to bring about a separation.
Abstract Beneficiation of ores by gravity concentration has been practiced for thousands of years, and while no longer the sole mainstay of concentration that it once was, and now having to share with newer developed processes, it is still one of the major methods that is in widespread use.

Gravity Concentration. The method is a gravity concentration method, and helps to separate bulk materials such as minerals of different specific gravity, based on their relative movement due to gravitational and other forces.

desliming, gravity concentration, magnetic concentration and agglomeration of concentrates. The industrial trend is to reducethecost,bothcapitalandoperative,byenhancingunit capacities, reducing energy consumption, giving flexible flow sheet for pre-concentration of values at coarse sizes at 1, 2] and FIMI [3].
fluorspar, tin, tungsten ores etc. The gravity separation processes are comparatively cheaper and environment friendly. Gravity separation of two minerals with different specific gravity is carried out by the relative movement in response to force of gravity and one or more other forces. Normally one of the forces is resistance to motion by a fluid, usually water.
