Beneficiation Of Coal Process

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
