Abstract. Coal is the most abundant fossil fuel and about 42 % of the world electricity is generated through coal fired power stations. However, mechanized mining has led to an increase in the quantity of fine coal production. The value of the fine coal necessitated the selection of the correct equipment for the gravity beneficiation of this …

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.
Beneficiation of non-coking coal is gaining ground in India. It not only reduces the volume of inert content to be transported to the power plant and also lowers the wear in the boiler houses.
