Mineral processing - Wikipedia

Gravity separation is also called relative gravity separation as it separates particles due to their relative response to a driving force. This is controlled by factors such as particle weight, size and shape. These processes can also be classified into multi-G and single G processes. The difference is the magnitude of the driving force for the separation. Multi-G processes allow the ...

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 Concentration Methods

Gravity separation has been suggested as an alternative to the use of mercury. However, many sites have pyrite and/or chalcopyrite. The gold is embedded in the ore in very fine particle sizes. That is not amenable to grinding using ball mills followed by gravity separation methods such as sluices or cyclonic concentrations. Consequently, there is a need for simple low-cost methods for leaching ...
