  • Minerals Special Issue Gravity Concentration
    Minerals Special Issue Gravity Concentration

    Gravity concentration is atpresent the main concentration process inthe mineral industry in terms of tons processed. The size that can beprocessed ranges from very coarse materials,coarser than 100 mm,concentrated through heavy media vessels or ROM jigs, to veryfine particles, about10 microns,concentrated through centrifugal processes.

    Gold Gravity Concentration Mineral Processing Metallurgy

    The object ofgravity concentrationis the separation of the heavy valuablemineralfrom the light worthless gangue. Complications are often introduced by the fact that various basemineralsmust 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 metal is ...

    Concentration. Concentration involves theseparation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic or electric (magnetic and electrostatic separation), and …

    The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams. Material in process often cannot be weighed without a disturbance of continuity; consequently, mill control must depend upon the ...
