Coal beneficiation processes 29 Coal Processing and
The commercial processes of coal beneficiation are based on the differences in some physical properties of the pure coal and the impure coal (refuse). The difference in specific gravity is the basis for the largest number of coal beneficiation processes in which case they are termed as Gravity Concentration Processes.

Coal beneficiation: theory and practice - ScienceDirect
2023.1.1 Abstract. Coal is a physical mixture of high carbon value coal and rejects. Coal beneficiation is nothing but the separation of these high carbon value coal from rejects (noncarbonaceous material) in a coal body. Although the theoretical knowledge of coal beneficiation is available aplenty in coal preparation books; it is essential that mineral ...

Recent advances in beneficiation for low rank coals
2015.6.1 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 ...
