In general, anything obtained from mining can be called as a mineral. So, for mining purposes, coal may be considered as a mineral. But, for geologists, a mineral is a naturally occurring homogeneous crystalline chemical substance with a definite
Coal is also an essential ingredient in the production of specialist products such as activated carbons, carbon fibre and silicon metals. Domestic Use In cold regions and in developing or underdeveloped countries coal is still used as fuel for cooking and a source of heat.
#0183;#32;Thousands of products are made with coal or coal byproducts, including aspirins, soap, dyes, solvents, plastics, and fibers such as rayon or nylon. Coal is an important ingredient in production of products that require activated carbon, carbon fiber or silicon metal.
Coal, one of the most important primary fossil fuels, a solid carbonrich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in
A coal fired power plant with a yield of 33% (which is the world average for these plants) will use roughly 400 kg of coal to produce one electric MWh. If ashes represent 20% of the incoming weight, we will get roughly 80 kg of ashes. 1 TWh #233;lectrique (one million MWh, or one billion kWh) means 400,000 tonnes of coal used, and 80,000 tonnes of ashes at the end.
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
A mineral is a naturally occurring substance, representable by a chemical formula that is usually solid and inorganic, and has a crystal structure. Heres a list of products and the minerals used to produce them: gt; Batteries: Antimony, Cadmium, Le...
Coal oil is a shale oil obtained from the destructive distillation of cannel coal, mineral wax, or bituminous shale, once used widely for illumination.. Chemically similar to the more refined, petroleumderived kerosene, it consists mainly of several hydrocarbons of the alkane series, with 10 to 16 carbon atoms in each molecule, with a boiling point of 175#176;C to 325#176;C (347#176;F to 617#176;F
#0183;#32;Coal is a type of combustible fossil fuel that is one of the primary sources of electricity across the world, along with oil. Coal is blackish rock composed of carbon, hydrogen and oxygen that occurs naturally underground.
#0183;#32;Coal mining, extraction of coal deposits from the surface of Earth from underground. Coal has been used since the Bronze Age, 3,000 to 4,000 years ago, and was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries.
Coal is softer than most of the metalliferous minerals and coal drills are therefore electrically operated. In fact electricity is the power in coal miens, wheras compressed air is the main power in underground metal mines. Extraction of coal is comparatively easy. Roof of coal is comparatively soft and erumbly.
In simple terms, coal is a mixture of two components: carbonbased matter (the decayed remains of prehistoric vegetation) and mineral matter (which comes from the ground from which the coal is dug).
Coal is also used in manufacturing. If coal is heated the gases, tars, and residues produced can be used in a number of manufacturing processes. Plastics, roofing, linoleum, synthetic rubber, insecticides, paint products, medicines, solvents, and synthetic fibers all include some coalderived compounds.
#0183;#32;Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.

#0183;#32;Coal geologists study their subject the same way that other geologists study other rocks. But instead of talking about the minerals that make up the rock (because there are none, just bits of organic matter), coal geologists refer to the components of coal as are three groups of macerals: inertinite, liptinite, and vitrinite.
