mineral processing - Concentration | Britannica

mineral processing - mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic ...

Role of air core in particle separation in cyclones ...

The separation of lighter particles with specific gravity close to the separating fluid was improved when the air core was suppressed. Numerical simulation studies showed that a higher tangential velocity and a lower radial velocity is the reason for better separation efficiency in the absence of the air core.

Basics of Gemstone Density and Specific Gravity - Gem Society

The density of minerals within a solid solution series may vary linearly with composition change. You can see chemical substitution's effect quite dramatically in the example of the orthorhombic carbonate minerals aragonite and cerussite.Aragonite is CaCO 3 and has a specific gravity of 2.95. Cerussite has the same crystal structure as aragonite.

Air classifier - Wikipedia

An air classifier is an industrial machine which separates materials by a combination of size, shape, and density.. It works by injecting the material stream to be sorted into a chamber which contains a column of rising air.Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the material to be sorted up into the air.
