Gravity Concentration An Separation - ilristorantelatorreit

Gravity concentration is the separation of minerals based on differences in specific gravity A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact

The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 193 for gold from 52 for pyrite

Mineral processing - Wikipedia

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 forces, magnetic forces, buoyant forces), one of which is resistance to motion (drag force) by a viscous medium such as heavy media, water or, less commonly, air
