More### 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: i.e. 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 force. One type of gravity separator lifts the material by vacuum over an inclined vibrating screen covered deck. This results in the material being suspende

01-01-2016 Feed sizing is an important pre-treatment to efficient gravity separation by a film flow. When this is satisfied, the smallest and heaviest particles will work their way to the bottom behind any obstruction as the water flowing over the obstruction lifts the lighter particles towards the top and eventually over the obstacle.

12-10-2018 Generally, when the quotient is greater than 2.5 (whether positive or negative), then gravity separation is relatively easy. With a decrease in the value of the quotient the efficiency of the separation decreases and below 1.25, gravity separation is not feasible. There are several types of gravity separation methods.

01-01-2016 At fine particle sizes, separation by density difference under gravity becomes less efficient. At this size range flotation is the dominant separation process, although 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.
