Coal preparation is a stage in the coal supply chain that follows mining but precedes shipment to the final end user. For many operations, runofmine coal consists of a composite mixture of carboniferous material and various noncoal impurities, such as rock, shale, clay, and water. Coal preparation, also denoted washing, cleaning, processing ...

There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]

Bituminous: Even greater pressure results in the creation of bituminous, or "soft" coal. This is the type most commonly used for electric power generation in the It has a higher heating value than either lignite or subbituminous, but less than that of anthracite. Bituminous coal is mined chiefly in Appalachia and the Midwest.

Coal is a combustible rock mainly composed of carbon along with variable quantities of other elements, mostly hydrogen, sulphur, oxygen and nitrogen. Coal occurs as layers, called coal beds or coal seams, that are found between other sedimentary rocks. Coal is slightly denser than water but less dense than most of the rocks of the Earth's crust ...
