Coal characterisation in mineral beneficiation

Jul 30, 2018 In the posite beneficiation system of coking coal in India, usually three types of products are obtained clean coal, middlings, and rejects It is observed that the proportion of middlings is rising day by day on one hand, and on the other the yield of clean coal is decreasing in the washeries because superior grade raw coal is depleting gradually
