COAL BENEFICIATION IIM

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

Coal Beneficiation Technology 2007 Initiatives, Policies

Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.
