• 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 ).

    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.

    Coal density is among the important parameters for reservoir engineering purposes and is inserted as an input property in simulation studies. Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity [2].The bulk density of a coal consists of the matrix and the void space, with the latter being

    The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the “concentrates,” in which the precious
