Coal Ash Beneficiation and Refining Options

Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.

Beneficiation Technology

A method of beneficiating coal in which the coal is conditioned by agitating it in the presence of a dense halogenated hydrocarbon and a surface active agent to effect a transfer of surface water from the coal to mineral matter associated therewith and an agglomeration of the mineral matter and to envelop the coal in a film of the surface active agent.

The dry separation methods for coal beneficiation have been regaining attention in the past decades. A number of improved or newly designed devices have been developed—one of them is a negative pressure pneumatic separator (NPPS). The said method of separation is based on the differences in the physical properties between coal and gangue minerals, such as the grain density, size, and shape.
