Gravity Separation and Desliming of Fine Coal: Pilot-Plant ...

The first Reflux Classifier performed a density separation that produced a coal product contaminated with fine high-ash slimes. This was then washed in the second Reflux Classifier to remove the fine clays and mineral matter. This combination reliably produced a clean coal product and allowed gravity separation performance to be extended from the usual eight-fold limit of upper to lower size ...

What is gravity separation? - Quora

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.

Mineral processing - Wikipedia

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal forces, magnetic forces, buoyant forces), one of which is resistance to motion (drag force) by a viscous medium such as heavy media, water or, less commonly, air.

Dry Separation Method -

Dry separation methods can basically be broken down into three main types of mechanical separation procedures: air classification, screening and specific-gravity separation. Air Classification The development of air-classification equipment, like most processing equipment, is an ongoing process.
