An Evaluation of the Significance of some Laboratory ...

coking coal to produce metallurgical grade coke comes from the bituminous grade coals, which constitutes about 52% of the world’s resources of coals. However, only about 5% of the world’s supply of coals is prime coking and suitable for straight carbonization (Worldcoal, 2007; Bujnowska and Collin, 1992). Coal is a readily combustible sedimentary rock containing more

West Cumbria Mining - What is Coking Coal / Metallurgical ...

Coking coal, also known as metallurgical coal, is used exclusively as an essential ingredient for steel production. The coal is ‘baked’ in a coke oven which forces out impurities to produce coke, which is a form of almost pure carbon. Modern steel plants, the likes of which are predominantly found in the UK and Europe, include extensive gas treatment and capture to significantly

Metallurgical Coal – IspatGuru

2018-09-25  Metallurgical coal is also called ‘met coal’ or ‘coking coal. It is a bituminous coal which allows the production of a coke suitable to support a blast furnace (BF) charge. It is distinguished by the strong low-density coke produced when the coal is heated in a low oxygen (O2) environment or in absence of air to reduce mineral impurities (e.g. less sulphur,
