Gravity Separation Gravity Separator Machine for Sale ...

Gravity beneficiation is a method of sorting ore in a certain fluid medium according to the difference in mineral density. The gravity separation process is carried out in a fluid medium, usually water, and sometimes heavy medium (heavy liquid or soliquiod). The essence of gravity separation processing is summarized as a loose-layered-separation process.

PRINCIPLES OF GRAVITY SEPARATION

The specific gravity of a particle is the ratio of its density to some standard substance, the standard usually employed being water with a unit of 1. Particles having a specific gravity of less than 1 will float on water while particles with a specific gravity greater than 1 will sink. Gravity separators use air as a standard rather than water. Since
