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.
Gravity Separation - an overview | ScienceDirect Topics
Gravity separation relies on the differences in density of minerals to provide efficient separation. The ease and efficiency of separation are dependent on a number of factors, including relative density, particle size and shape, liberation – all of which affect the selection of equipment type.

Gravity Separation - ttms999.com
Gravity Separation Gravity separation uses differences in specific gravity (SG) between various minerals to achieve a separation, and is normally a wet process although examples of dry gravity separators exist.
Mineral Comminution and Separation Systems
dense mineral particles amenable to gravity separation. Major parts of the concentrates and the tailings occur from th e flotation process, and these are submitted to solid-liquid separation for delivery and/or disposal. The equipment used for these purposes are thickeners 23 and 26, vacuum filters 24 …

Gravity Separation | Gravity Separator Machine for Sale ...
Gravity separation is an effective method for separating minerals of significantly different densities. It is an industrial method of separating two components from a suspension or any other homogeneous mixture where separating the components with gravity is sufficiently practical.
Mineral processing | metallurgy | Britannica
Mineralogical analysis A successful separation of a valuable mineral from its ore can be determined by heavy-liquid testing, in which a single-sized fraction of a ground ore is suspended in a liquid of high specific gravity. Particles of less density than the liquid remain afloat, while denser particles sink.

Falcon UF Gravity Concentrators | Sepro Mineral Systems
Thanks to the Falcon UF Gravity Concentrators, there is now a way to economically recover and upgrade particles as fine as three microns. The primary objective of the Falcon UF Gravity Concentrator is to scavenge ultra-fine mineral particles that are typically rejected from mining plant processes as slimes.
TANTALUM, TIN AND TUNGSTEN
The objective of the grinding circuit should be to liberate the mineral without over-grinding, with valuable mineral being recovered as coarse as possible in the subsequent gravity circuits. The degree of grinding required will thus depend on the liberation characteristics of the minerals.
