Jan 02, 2011Density is the material per unit volume. Specific gravity is the ratio of the density of a substance to the density of a reference substance. The key difference between density and specific gravity is that density is an absolute value, while specific gravity is a relative value for a substance.

Gravity separation process is the earliest method that applied in mineral processing. According to the density difference among mines and the difference of gravity, fluid power and mechanical force in moving medium, mines realizes mineral grains separation through density difference, gravity separation method still occupies an important position in the contemporary mineral processing.

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.
