Beneficiation - an overview ScienceDirect Topics

T. Robl, in Coal Combustion Products (CCP's), 2017 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).
