Coal Beneficiation

2018-3-19  The need for coal beneficiation • Removal of ash, water and contaminants raises performance, resulting in cleaner thermal coal power • High quality feedstock is needed to fully benefit from HELE technology • Reduces carbon footprint in life cycle analysis where transport is included • Higher value and non-energy products can be produced

Coal Beneficiation - an overview ScienceDirect Topics

Coal beneficiation, or coal preparation as it is also termed, refers to the processes through which inorganic impurities are separated from raw mined coal, thereby providing improved combustion characteristics to the fuel produced. The separation processes used are primarily based on exploiting the physical differences between the organic (i.e., coal) and inorganic (i.e., ash) components.
