Coal mined from the Talcher region of Odisha, India is known to be highash, surfaceoxidized, and noncoking in nature. It is quite challenging to beneficiate such lowgrade coal by physical or physicochemical processes due to its oxidized nature and the presence of complex ash forming mineral matter in its matrix. Chemical beneficiation is one of the alternative process to such .

Apr 29, 2011 · An attempt has been made to beneficiate the Indian coking coal fines by a combination of Spiral, flotation and Oleo Flotation processes. Beneficiation studies were also carried out on coal fines using flotation and oleo flotation by splitting at size fraction of and size were treated in flotation and .
The magnetic demineralization of coal can produce a fuel containing lower leveIs of sulphur and ash forming minerals. The ability of the magnetic separation technique to process material over a wide range of particle sizes (I1000 µm) and to operate on either liquid or gaseous feed enables a number of possible coal processing appliions.

The lignites vary greatly in moisture content, ash content, heating value, and in virtually every other identifiable or quantifiable characteristic. Consequently, none of the conventional coal cleaning, or beneficiation, methods are broadly applicable to the field of lignite beneficiation. A description is presented of new lignite beneficiation methods, which are complete departures .
Jan 04, 2012 · Coal fly ash beneficiation. Coal is a useful and important resource in human consumption in its long history. It has been played a crucial role in production of electricity and heat, and also used for industrial purposes such as refining metals. Coal forms when dead plant remains are converted into peat, and then into lignite or anthracite.
The scheme of beneficiation indied here is a simple and effective technique that does not take into consideration either small coal or fines. This simple scheme may be applicable both for consumption in the power sector and the cement industry.
The coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity.
