Dry beneficiation of coal - ScienceDirect

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.

1.1.1 Dry Beneficiation Processes: Dry separation essentially relies on separation of components based on some differences in the physical or surface properties of the components. These may be physical/mechanical, magnetic, or electrical. Mechanical separation may be effective down to 1mm particle size, while electrical and magnetic are most suitable below 1mm particle size. In general, all beneficiation

In principle, dry technologies are similar to most wet beneficiation techniques that are currently industrialized. These operate based on the relative movement of a particle within a medium in accordance to the difference in said particle and medium density. In the simplest terms, particles denser than the medium sink and those less dense, float. The preferred method of dry dense medium ...
