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.

    How And Why To Value A Coal Mine Fti Journal

    Metallurgical coal differs from thermal coal, used for energy and heating, by its carbon content and its caking ability. Caking refers to the coal39s ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coalgenerally classified as a metallurgical gradeis harder and blacker. It contains more carbon and less moisture and ash than low-rank coals.

    The grade of coal and its caking ability is determined by the coal39s ranka measure of volatile matter and degree of metamorphismas well as mineral impurities and the ability of the coal to melt, swell and resolidify when heated. The three main categories of metallurgical coal are.

    Coke making is effectively the carbonization of coal at high temperatures. Production normally takes place in a coke battery located near an integrated steel mill. In the battery, coke ovens are stacked in rows. Coal is loaded into the ovens and heated in the absence of oxygen up to temperatures around 1,100 degrees Celsius 2,000 degrees Fahrenheit.

    Without oxygen, the coal does not burn. Instead,it begins to melt. The high temperatures volatilize unwanted impurities, such as hydrogen, oxygen, nitrogen, and sulfur. These off-gasses can either be collected and recovered as by-products or burned off as a source of heat.

    Do You Know What These Mining Terms Mean

    To many people, the laws governing exploration for minerals on public domain lands and leasing of federal minerals may seem arcane. The principal means of acquiring mining rights on federal lands is location of mining claims under the Mining Law of 1872. That statute, enacted when the West was being settled and federal policy encouraged disposal of public domain lands, still governs the location of metallic minerals such as gold, silver, tin and copper, as well as other minerals including uranium, building stone other than common varieties, and even diamonds.
