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.

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.

Gravity Separation Technology for Oil Sands E MJ

Gravity Separation Technology for Oil Sands. This year, the synthetic crude producers in Alberta predict that they will average 721,000 barrels per day, which amounts to mining 1.4 million tons per day of oil sands. This figure is expected to double in the next 10 to 15 years. Moving that amount of material requires skill, technology and patience.
