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 put in a liquid media of adjustable specific gravity to separate the lighter coal (low ash) from heavier coal (high ash).

Abstract: As it comes from the mine, coal is known as run-of-mine (ROM) coal and consists of a range of sizes from chunks to small particles mixed with some dirt and rocks. In most cases, this ROM coal needs some degree of preparation and beneficiation to meet certain market requirements as sizes, ash, sulfur, moisture, and heating values.
