gravity concentration of gold by pressure jigs

Mineral processing - Wikipedia

Gravity concentration. 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 ...
