ore gravitational separation

  • Gravity separation : ALS

    Gravity separation is achieved based on the difference in specific gravity (SG), shape and particle size of the valuable minerals or metals, as compared with the gangue or host rock and the carrying medium.

    A successful separation of a valuable mineral from its ore can be determined by heavyliquid testing, in which a singlesized fraction of a ground ore is suspended in a liquid of high specific gravity. Particles of less density than the liquid remain afloat, while denser particles sink. Several different fractions of particles with the
