gravity separation range

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 5-10 μm, provided the concentration criterion is favourable.
