    Particle Analysis in Mining and Minerals

    Gravity Separation. Gravity separation relies on differences in material mass to separate minerals. Methods include jigs, sluices, spirals, shaking tables, fine particle separators, and hydrosizers and cyclones. Gravity separation is separation based on weight only and is directly affected by particle size since volume is proportional to weight.

    How Gravity Separators Work | Density Separation Equipment

    The gravity separator, also known as fluidizedbed separator, air table, or density separator, makes a highly sensitive dry separation on the basis of one of three particle characteristics – density, size or shape. When two of these characteristics are controlled within certain limits, the gravity separator is unmatched in its ability to ...

    coal gravity separation how it works

    Coal washing involves grinding the coal into smaller pieces and passing it through a process called gravity separation. One technique involves feeding the coal into barrels containing a fluid that has a density which causes the coal to float, while unwanted material sinks and is removed from the fuel mix.
