PRINCIPLES OF GRAVITY SEPARATION

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 air is lighter than water, the relative difference between particles of differing weights is widened. For this reason, the gravity separator is
