Dry beneficiation of coal ScienceDirect

Oct 01, 1984 Dry beneficiation is an alternative approach. The present work is a review and critical assessment of topics relevant to dry processing of coal, comprising comminution, size classification, characterisation and analysis, sorting at coarse sizes, mechanical beneficiation according to density at medium sizes, and electrical and magnetic beneficiation at fine particle sizes.

Modelling of Hard Coal Beneficiation Process Utilising

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.
