    Physical Beneficiation - an overview | ScienceDirect Topics

    The physical beneficiation processes are usually utilized to upgrade good quality coals. On the other hand, coal fines ( 0.5 mm) are inevitably produced during coal processing, mining, etc. and more coal fines will be produced with the maturity of mechanized mining and processing technology. These coal fines need to be utilized to reduce landfills

    Recent advances in beneficiation for low rank coals

    Jun 01, 2015 Coal beneficiation is one of the most effective methods for removing minerals (such as gangues and pyrite) and pollutants (such as sulfur) before the burning of coal. In general, the beneficiation process of low rank coals is more difficult to achieve than that of bituminous and/or anthracite coals. However, about 50% of the world's total coal
