Coal mining - Coal preparation | Britannica

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 intrusions.In 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.

What You Should Know About Metallurgical Coal

21.08.2020· Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking. Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces. Heat and pressure cause physical and chemical changes that result in carbon-rich coal.
