Metallurgical coal - Wikipedia
Metallurgical coal or coking coal 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. The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that produces coal for coking, to ensure a stable and low-cost supply.
What You Should Know About Metallurgical Coal
Jul 15, 2019 · 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.
The Types of Coal: Composition, Usage, and Energy Value
Jan 29, 2020 · Coking vs. Steam: Coking coal, also known as metallurgical coal, has low sulfur and phosphorus content and can withstand high heat.Coking coal is fed into ovens and subjected to oxygen-free pyrolysis, a process that heats the coal to approximately 1,100 degrees Celsius, melting it and driving off any volatile compounds and impurities to leave pure carbon.
Coal prices and outlook - U.S. Energy Information ...
Coking coal must be low in sulfur and requires more thorough cleaning than coal used in power plants, which makes the coal more expensive. In 2018, the average delivered price of coal used to make coke was about $129 per short ton—about three times higher than the price of coal delivered to the electric power sector.

Anthracite Coal is a hard, compact variety of mineral coal that has a high luster. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. It has the highest carbon count, the fewest impurities, and the highest calorific content of all types of coals, which also include bituminous coal and lignite. It is mostly used for stone and metallurgical purposes.
How is Steel Produced? | World Coal Association
Coking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a hard porous material - coke.
