Minerals Special Issue : Gravity Concentration

Oct 31, 2020  Gravity concentration is at present the main concentration process in the mineral industry in terms of tons processed. The size that can be processed ranges from very coarse materials, coarser than 100 mm, concentrated through heavy media vessels or ROM jigs, to very fine particles, about 10 microns, concentrated through centrifugal processes.

Jig - an overview ScienceDirect Topics

Jigs are continuous pulsating gravity concentration devices. Jigging for concentrating minerals is based exclusively on the differences in density of the particles. The elementary jig (Fig. 13.29) is an open tank filled with water.A thick bed of coarse heavy particles (ragging) is placed on a perforated horizontal jig screen.

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 ...

Choosing The Correct Gravity Separation Machine

From simple jigs to high G-force gravity centrifuges, knowing which one to use for optimal mineral processing can be complicated and difficult to understand. There are so many factors to consider when creating the ideal circuit; one critical element is the size of the particles you intend to recover.
