Beneficiation an overview ScienceDirect Topics

In dry beneficiation of coal, coal and mineral matter are separated based on differences in their physical properties such as density, shape, size, luster, magnetic susceptibilities, frictional coefficient, and electrical conductivity [23–25]. Dry beneficiation gives a clean coal as well as reduces some of the polluting elements associated with minerals.
