Coal mined from the Talcher region of Odisha, India is known to be high-ash, surface-oxidized, and noncoking in nature. It is quite challenging to beneficiate such low-grade 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 problems ...

The energy sector in India is highly dependent on coal as a fuel. At present, most of the domestically produced thermal coal is burned raw or after minimal beneficiation.
Attaining an ash content of 34 percent or lower at reasonable yields may even be impossible for coal from certain mines in India. Coal beneficiation is a process where coal is subjected to a medium of defined specific gravity. Heavier coal sinks rejects and lighter coal floats clean coal.

India is having a large reserves of coal concentrated mainly in the east and north-east region of India. The quality of coal is poor in comparison to that of other countries due to higher ash content and low calorific value. This is because Indian coals are typically of drift origin and the mineral matters are finely distributed inside the coal

Coal preparation, or beneficiation, is a series of operations that remove mineral matter i.e., ash from coal. Preparation relies on different mechanical operations, which will not be discussed in detail, to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.
May 24, 2020 Majority of Indias coal production is non-coking coal coking coal has to be imported. Additionally, indigenous coal is of average quality with high ash and low calorific content. This means a lot of investment has to be made to improve its grade this process is called coal beneficiation.
