How Gravity Separators Work | Density Separation Equipment
The gravity separator, also known as fluidized-bed separator, air table, or density separator, makes a highly sensitive dry separation on the basis of one of three particle characteristics – density, size or shape. When two of these characteristics are controlled within certain limits, the gravity separator is unmatched in its ability to ...

Gravity Spiral Concentrator Working Principle
Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4)

Choosing The Correct Gravity Separation Machine
High G-Force Gravity Concentrators. The higher the G-force, the smaller the minerals you can recover with a given technology. All of the Falcon Gravity Concentrators are high G-Force devices that achieve forces from 100-600Gs. When these forces are applied to a mineral feed, particles as fine as 3 microns in size can be selectively recovered.

Water Handbook
Conventional gravity and pressure rapid filters operate downflow. The filter medium is usually a 15-30 in. deep bed of sand or anthracite. Single or multiple grades of sand or anthracite may be used. A large particle bed supports the filter media to prevent fine sand or anthracite from escaping into the underdrain system.

Gold Gravity Separation
Gold Gravity Separation. The gravity separations are simple and separate mineral particles of different specific gravity. As the density of gold mineral is much bigger than gangue mineral, for the gold mine which has gold particles people often use the gravity separation process. Gravity concentration is a proven process for mineral beneficiation.
