Raw coal coming from mines is washed to remove the ash contents to make them fit for feeding into boilers, particularly those of steel plants. Barring a few instances, a coal washery does not form part of a coal mine in India. Total installed capacity of washeries in India is around 131.24 million tonne per year (MTY) as on 31.3.2016.

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.

The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making.
