Gravity Separation – Oliver Manufacturing
How Gravity Separation Tables Work. The gravity separation table, or air table, is commonly used to separate particles by weight and density. A separation table can be used for any dry material as it moves on a “fluidized” bed of air across the table.The separator creates eccentric motion and has an adjustable uphill tilt which separates heavier particles from lighter particles.

Heavy media separation is a gravity separation process that crush ores into a certain size, and make the density of the fluid heavier than water (that is heavy medium). According to the Archimedes' principle of buoyancy, when density is less than media, ore particles will float; when the density is greater than media, ore particles will sink.
