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 ...
