COKING COAL BENEFICIATION | SciTech Connect

 · The basic purpose of beneficiation is to reduce the ash forming impurities from raw coal so that better coal with less ash content can be produced. If these ash forming constituents are not removed, and coal is directly charged to the coke-ovens, the ash content in coke will increase and subsequently more slag will be produced in the blast furnace thereby lowering the efficiency of the …
