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(2007) DRY BENEFICIATION OF COAL—A REVIEW Mineral Processing and Extractive Metallurgy Review: Vol 28, No 3, pp 177234DRY BENEFICIATION OF COAL—A REVIEW: Mineral 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 beneficiationDry beneficiation of coal: A review CORE
