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.

Introduction. 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).

Coal 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

Remarks on Coal Beneficiation Process and Diagram. "SubA" Coal Flotation Systems have been successful for recovery of both coarse and fine coal. It is important, however, to employ a twostage circuit for maximum efficiency in saving the plus 28 mesh fraction which is normally the most difficult to float.

Thus, three products are produced by this process. 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.

JHARIA REJECTS. Tata Steel coal washery rejects are produced as byproducts from its Jamadoba and Bhelatand Coal Preparation Plants. In both the plants, coal washery rejects are mixed with middlings to produce the end product '2PR or 2Product Rejects' as a part of the process. Quality of 2PR ranges from G13 to G17 equivalent of CIL coal grade.

After thermal upgrading, the coal is put through a deep bed stratifier cleaning process to separate the pyrite rich ash from the coal. When fed a typical low rank western coal, the SynCoal process can provide a product with a heating value of up to 12,000 BTU/lb with moisture and ash contents as low as 1% and %, respectively [ 100 ].
