Dry beneficiation of coal ScienceDirect

1984-10-1  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.
