In the event, the process also results in loss of coal fines, usually 610 tonnes per day from a single washery plant (Tiwary Dhar 1994; Ghose 2001). The third and fourth kind of WW is generated from steel plants and TPPs respectively, which are responsible for steel production and electricity generation from the washed coal.

India has proven reserves of coal amounting to ∼126 billion tonnes out of which ∼18 billion tonnes is metallurgical or coking coal, ∼107 billion tonnes is thermal coal, and ∼1 billion tonnes is tertiary coal (Venugopal et al., 2016).Coal preparation or washing in India started in the early 1950s for metallurgical coal (Venugopal et al., 2016).
WhatsApp: +86 18838072829Coal preparation is the removal of undesirable material from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved. Washability Study

Clean coal is supplied to steel plants, the middlings to thermal power stations, and the rejects are usually dumped near the washery or utilized for power generation. Summing up, raw coal is usually crushed to 15 mm and then screened into three fractions 1525 mm, mm and mm.
