Metallurgical coal or coking coal[1] is a grade of coal that can be used to produce good-quality coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. [2][3][4] The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that ...
The price of metallurgical coal is volatile [115] and much higher than the price of thermal coal because metallurgical coal must be lower in sulfur and requires more cleaning. [116] Coal futures contracts provide coal producers and the electric power industry an important tool for hedging and risk management.
Coking coal (metallurgical coal or "met coal") is used in the manufacture of steel. A good coking coal must have excellent agglomeration properties, a high carbon content, and a low content of sulfur, phosphorus, and ash. The best unblended coking coal is high quality medium-volatile bituminous coal. [18]
Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or oil in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur ...
Anthracite. Anthracite, also known as hard coal and black coal, is a hard, compact variety of coal that has a submetallic lustre. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals. The Coal Region of Northeastern Pennsylvania in the United States has ...
Coking is the process of heating coal in the absence of oxygen to a temperature above 600 °C (1,112 °F) to drive off the volatile components of the raw coal, leaving behind a hard, strong, porous material with a high carbon content called coke. Coke is predominantly carbon. Its porous structure provides a high surface area, allowing it to ...
Coal mining is an industry in transition in the United States. Production in 2019 was down 40% from the peak production of 1,171.8 million short tons (1,063 million metric tons) in 2008. Employment of 43,000 coal miners is down from a peak of 883,000 in 1923. [ 1 ] Generation of electricity is the largest user of coal, being used to produce 50% ...
Former AHM blast furnace in Port of Sagunt, Valencia, Spain. A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being supplied above atmospheric pressure. [citation needed]
