The quantum of coal fines below 6 mm in run-of-mine (ROM) coal has been increasing due to progressive mechanization of mining methods which has created a substantial incentive, worldwide, to develop suitable fine coal beneficiation techniques. The majority of the efforts have been directed toward reduction in ash/sulfur contents in clean coal. The …

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.
Coal beneficiation using spirals is an age-old technique and is still widely accepted, operated satisfactorily worldwide to reduce the ash content of the coal. A handful of research outcomes on the application of spiral concentrators for beneficiating coal have been listed in this section.
