2020-2-2  Raw coal fed on to the vibrating bed having crosswise and vertical slope. Air supplied through air holes in the beneficiation bed which agitates the raw coal resulting in stratification of coal as per its relative densities -lighter coal forms the upper layer and heavier coal forms the lower layer. Upper good coal

INVESTIGATION OF DRY COAL BENEFICIATION WITH

Additionally, HMS plants cannot be constructed in underground. Automated optical sorting of coal is a competing technology with HMS when the colour difference between coal and its impurities is visible. Therefore, optical sorting depending on colour differences between minerals can be introduced to coal beneficiation systems.
