  • Gravity Separation - ScienceDirect

    2016-1-1  Separation of gold by density difference dates back to at least 3000 BC as depicted in writings from ancient Egypt. The principle employed in gravity separation goes back further in time to the formation and weathering of the rocks and the releasing of the minerals they contain and the transport of the mineral grains by heavy rains.

    S. Gray, in Gold Ore Processing (Second Edition), 2016. Abstract. Gravity separation relies on different specific gravity of minerals and their relative motion under gravity and drag forces. This chapter describes units, circuits, and strategies that are used to recover gravity-recoverable gold (GRG) from very high-grade gold particles and from sulfidic particles with low-grade gold content.

  • The Gravity Separation Methods Used To Process Gold?

    2019-9-17  Gravity separation is one of the common methods for gold extraction, which uses different specific gravity of materials and different settlement velocity in the medium to carry out stratified separation. Generally, when gold mostly exists in the form of monomer natural gold, the density difference between gold and gangue is large, it is more effective and economical for gold separation.
