  • Minerals Special Issue : Gravity Concentration

    2020-10-31  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.

  • A Simple Recipe Guide to Gravity Concentration

    Gravity concentration as a mineral processing technique was well established on a large scale by the first century AD Romans during the hydraulic gold mining of the mountains in north-western Spain. Gravity concentration has diminished as a first-choice beneficiation process in favour of flotation, magnetic separation and hydrometallurgy, and this has resulted in an industry loss of practical ...

  • Gravity Concentration Methods SpringerLink

    Gravity Concentration — the separation of minerals by virtue of specific gravity — is one of the oldest forms of mineral processing. Whilst its relative importance has declined in the twentieth century, the high cost of alternative processes, along with the development of a range of high capacity devices has led to something of a renaissance of gravity concentration.
