Physical Processing Of Coal

The process is a precursor to the removal of pyritic sulfur and ash-forming components of coal by physical coal clean- ing methods. Since the process is chemical in nature and it does remove pyritic sulfur when combined with a physical coal cleaning process, it has been included in this study of chemical coal cleaning processes.

Coal found in sedimentary rock, is crushed into the appropriate size and used as fuel for electricity generation or the iron-making process. Lumps of coal can be used directly as a fuel. However some coal is first washed to make it into 'high grade coal'. It can also be sorted into various sizes, depending on what the fuel is required for.

Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration

Coal is cleaned industrially by freeing the occluded mineral impurities and physically separating the coal and refuse particles on the basis of differences in density, settling characteristics, or surface properties. While physical methods are very effective and low in cost when applied to the separation of coarse particles, they are much less effective when applied to the separation of fine ...

The degree of change undergone by a coal as it matures from peat to anthracite is known as coalification. Coalification has an important bearing on coal's physical and chemical properties and is referred to as the 'rank' of the coal. Ranking is determined by the degree of transformation of the original plant material to carbon.

Aug 15, 2019· Why is Coal Valuable? Coal is a fossil fuel formed from dead plant matter trapped between rock deposits.. Over a period of millions of years, biological and geological processes turn this material into peat and then through further metamorphosis into lignite, sub-bituminous coal and finally anthracite coal.. Coal has been used as an energy source throughout human history.
