30 Million tonnes of coal is washed every year in Indian coal washeries. 20 - 30% of coal in the form of fines are produced and are being lost as tailings. Veryfew washeries have the facilities to treatthese coal fines. The standard existing coal beneficiation techniques are not effective to recover fine coal from these coal washery tailings. ...
III. COAL WASHING TECHNOLOGY OPTIONS Clean coal technology being practiced in coal washeries in India, as pre-combustion clean coal technology, mainly focus on cleaning of coal by removing ash from coal. Earlier only coking coal was being washed because steel making needs coking coal of ash of 17 to 18%.
Beneficiation of non-coking coal is gaining ground in India. It not only reduces the volume of inert content to be transported to the power plant and also lowers the wear in the boiler houses. For special applications such as the fuel for integrated gasification combined cycle plant (IGCC), the ash content in the coal should preferably be below 15 %. Indian coals are characterized by high ...

The quantum of coal fines below 6 mm in run-of-mine (ROM) coal has been increasing due to progressive mechanization of mining methods which has created a substantial incentive, worldwide, to develop suitable fine coal beneficiation techniques. The majority of the efforts have been directed toward reduction in ash/sulfur contents in clean coal. The beneficiation techniques may be broadly ...

Ash Beneficiation Technologies Ash Beneficiation Technologies. Thermal beneficiation is the use of combustion to reduce the level of carbon in the ash. thermal beneficiation also eliminates ammonia issues and can improve fineness and uniformity. successful thermal beneficiation technologies have been commercially deployed since 1999 keppeler 2001.
-6 mm coal will be diverted to the Fines feed tank. The fines tank is also fed with water & magnetic separator under flow to prepare the slurry, which will be pumped to the screw classifier in the H.M Bath Plant. The screw classifier is used to classify fine coal in order to remove -500 micro fractions and hence deslime the fine coal fraction.
