  • Gravity Separation an overview | ScienceDirect Topics

    At fine particle sizes, separation by density difference under gravity, becomes less efficient At this size range flotation is the dominant separation process, though the application of centrifugal acceleration has extended the useful separation size by gravity processes down to 510 μm, provided the concentration criterion is favourableGravity concentration is the separation of minerals based upon the difference in density Techniques of gravity concentration have been around for millennia Some believe that the legend of the Golden Fleece from Homer’s Odyssey was based upon a method of gold recovery, which was to place an animal hide (such as a sheep’s fleece) in a stream containing alluvialGravity Concentration an overview | ScienceDirect Topics

  • Gravity separation Wikipedia

    Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: ie the components of the mixture have different specific weight All of the gravitational methods are common in the sense that they all use gravity as the dominant forceIt is also the only continuous gravity concentrator available that utilises the patented fluidbed feature for ensuring separation of high and low specific gravity minerals This fluidisation feature also ensures that the feed, concentrate and tails will not plug, bridge or pack as can happen with unfluidised gravity systems MT3500 Shaking TableGravity concentration systems – for enhanced productivity
