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.
