DRY BENEFICIATION OF COAL—A REVIEW: Mineral …

22-07-2009· However, dry beneficiation of coal has obvious advantages over wet processes. The dry processes for coal are based on the physical properties of coal and its associated mineral matters. Different types of equipment for dry beneficiation have been developed, based on the exploitation of physical properties such as density, size, shape, magnetic susceptibility, and electrical conductivity.

To intensify the production of coal, mechanisation of coal mining is gradually increasing. The process, being less selective, increases the quantity of shales, stones and other impurities in coal. Dry methods of separation of these impurities may serve as a preconcentration step prior to wet processes of beneficiation. Dry beneficiation will eliminate the energy intensive process of dewatering ...

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.
