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 ...
Raw coke. Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum 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.
Coke is made when metallurgical coal (also known as coking coal) is baked in an oven without oxygen at temperatures as high as 1,000 °C, driving off the volatile constituents and fusing together the fixed carbon and residual ash. Metallurgical coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. [94]
Bituminous coal is formed from sub-bituminous coal that is buried deeply enough to be heated to 85 °C (185 °F) or higher. Bituminous coal is used primarily for electrical power generation [1] and in the steel industry. Bituminous coal suitable for smelting iron (coking coal or metallurgical coal) must be low in sulfur and phosphorus. It ...
MGO produces 6.7 million tonnes of thermal and semi-soft metallurgical coal annually Liddell, Hunter Valley, New South Wales Liddell Open Cut is an established open-cut coal mining operation located 25 kilometres from SIngleton in the Hunter Valley. Liddell produces 3.4 Million tonnes of thermal and metallurgical coal annually
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.
In 2019-20 Australia exported 390 Mt of coal (177 Mt metallurgical coal and 213 Mt thermal coal) and was the world's largest exporter of metallurgical coal and second largest exporter of thermal coal. [3] While only employing 50,000 mining jobs nationally coal provides a rich revenue stream for governments. [4]
Alpha Metallurgical Resources, formerly Contura Energy (January 2021), is a leading coal supplier with underground and surface coal mining complexes across Northern and Central Appalachia. Contura owns large coal basins in Pennsylvania, Virginia and West Virginia which supply both metallurgical coal to produce steel and thermal coal to generate ...
