Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.
These plants normally practiced hand picking for the lump and egg sizes (more than three inches) and washed the coarser coal (three inches by one quarter of an inch). The fine coal (less than one quarter of an inch) was usually shipped raw. The reject from such a plant was unlikely to exceed ten percent of the runofmine (ROM) coal.

The Drift Theory of Coal formation. It was the difference in coal properties of Gondwana coals that led to the formation of the drift theory. The mode of deposition of coal forming can be explained as said below: Coal is formed largely from terrestrial plant material growing on dry land and not in swamps or bogs.

The defects which may occur in thermal power stations and washing plants, To feed the thermal power stations continuously with coal of specified properties. However, some negative developments are observed in various characteristics of coal and important problems may emerge because of its long time storing in open areas.
Thermalbased power plants can produce electricity from coal or other fuel sources. The coalfired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.

History of coal washing in india . Coal Preparation in India – A Historical Perspective The earliest record of systematic coal washing study in India was an attempt by Prof. William Galloway using a preBaum type Jig washer before World War I on tested Assam coals.
Feedstocks enter the gasifier at the top, while steam and oxygen enter from below. Any kind of carboncontaining material can be a feedstock, but coal gasification, of course, requires coal. A typical gasification plant could use 16,000 tons (14,515 metric tons) of lignite, a brownish type of coal, daily.

A coal derivative, a solidified carbon called coke, melts iron ore and reduces it to create steel. But most coal 92 percent of the supply goes into power production [source: Energy Information Administration]. Electric companies and businesses with power plants burn coal to make the steam that turns turbines and generates electricity.
