Beneficiation

8.3.1.5 Thermal beneficiation. Thermal beneficiation is the use of combustion to reduce the level of carbon in the ash. Thermal beneficiation also eliminates ammonia issues and can improve fineness and uniformity. Successful thermal beneficiation technologies have been commercially deployed since 1999 (Keppeler, 2001). This technology produces ...

Jul 18, 2018· 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 blast furnace.
