Coal preparation, or beneficiation, is a series of operations that remove mineral matter (, ash) from coal. Preparation relies on different mechanical operations (not discussed in detail here) to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.
The emission of pollutants like SO X, NO X, and suspended particulate matter (SPM) from coalfired power plants is a source of pollution for surrounding areas unless appropriate control measures are taken. In general, NO X and SO X are formed from the combustion of coal where air is used or where nitrogen and sulphur is present in the fuel.

The purpose of coal preparation is to reduce sulfur and other pollutants for utility application. The triboelectric dry beneficiation can work effectively for ultrafine coal particles of lt;200 mesh, and provide a unique opportunity for treating pulverized coal in power plants. High grade steam coal with low ash, low sulphur and high heat value can be obtained by this process, and then the ...

At the macroeconomic level, beneficiation leads to economic efficiencies and to pollution control. Beneficiation also adds value to Indian coals and improves their marketability. This is particularly true with the decreasing thickness of coal seams in mature mines, which correspondingly leads to the quality of coal declining.
COAL COMBUSTION AND POLLUTION CONTROL 195 POLLUTION CONTROLS Installing pollution controls is another means to reduce specific emissions. Most of these controls are designed to reduce a particular pollutant ( SO 2), although there are some cobenefits to installed controls, such as mercury emis sions reductions, as will be discussed.

Controls may be required on individual sources such as ventilation exhausts if they have a significant effect on ambient particulate levels. If coal crushers or dryers are used, fabric filters or other systems should be used to recover coal and reduce particulate emissions to levels below 50 milligrams per normal cubic meter (mg/Nm3).

AIR POLLUTION CONTROL MEASURES In coal mines, air pollution starts with removal of massive overburden7(OB) which discharges fine particles. It is followed by drilling/ extraction of coal and movement of extracted coal to the washery/ crusher/ Coal Handling Plant (CHP)8and finally transportation of coal to the consumer.
