Beneficiation - Wikipedia

Beneficiation can begin with in the mine itself. Most mines will have a crusher within the mine itself where separation of ore and gangue minerals occurs and as a side effect becomes easier to transport. After the crusher the ore with go through a grinder or a mill to get the ore into fine particles.

6.1 Coal Beneficiation Technology Options

For the beneficiation of coarse coal (larger than 5-6 mm), there are basically two wet routes: with dense medium based technologies, or with water-only technologies. Flotation and agglomeration principles will not work since the particles are too large and will sink, irrespective of the quality (save maybe the very lightest of density fractions).

Mechanism of a Coal Chemical-Leaching Process and Recovery of

ABSTRACT. Methods for enriching organic macerals in coal are of great importance, but, due to the yield constraint, physical-beneficiation methods are less effective. Chemical beneficiation using alkali followed by acid has been studied at the pilot stage with a batch of 500 kg of feed coal for three different coal fractions of the physical-beneficiation process using dense media cyclone and froth flotation.
