Minerals Special Issue : Gravity Concentration

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.

Gravity Concentration - an overview ScienceDirect Topics

Gravity concentration, a technology with its roots in antiquity, is based on the differential movement of mineral particles in water due to their different density and hydraulic properties. The method has seen development of a range of gravity concentrating devices, and the potential to treat dry to reduce reliance on often scarce water resources ( Chapter 10 ).

and below 1.25 generally, gravity concentration is not feasible. As mentioned above, besides the specific gravity, the motion of a particle in fluid also depends on its size. The efficiency of gravity concentration increases with an increase in particle size. The particle movement should be governed by the Newton's Law, Eq. 12 v = [ 3gd (P ' — Df i D 1 T2

The myth of gravity concentration to eliminate mercury

23-01-2021  Gravity concentration, as universally used, is an efficient method to separate gold particles -usually above 0.074 mm or 200 mesh- from the rest of the gangue minerals. Gravity separation in conventional gold processing plants is used to remove relatively coarse gold particles before entering the flotation or cyanidation circuit.
