Coal generally incorporates various amounts of mineral matter as impurity. The presence of

Coal Beneficiation Technology

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. – Wet process: Coal is crushed to smaller size and

Coal beneficiation has centered on two areas – physical and chemical. Now, there is a third area – biological. Physical cleaning separates undesirable substances, such as dirt, rocks and inorganic, or pyritic sulfur (sulfur combined with iron), from the coal. Often this is done using water. There is a difference in the density or weight of coal and other substances. Therefore,
