Semi-soft coking coal
Semi-soft coking coal occupies an important middle ground in the world of metallurgical coals. It is neither the highest-grade hard coking coal used to produce premium blast-furnace coke nor the…
Soft coking coal
Soft coking coal occupies a specific and important niche within the family of bituminous coals. It combines properties that make it partially suitable for metallurgical processes, particularly when blended with…
Hard coking coal
Hard coking coal is one of the most important raw materials in traditional iron- and steelmaking. Unlike thermal coal used mainly for power generation, this specialised grade of coal is…
Coking coal
Coking coal, also known as metallurgical coal, is a specialized type of coal used primarily for producing coke, the essential carbonaceous material in traditional iron and steelmaking. Unlike thermal coal…
Metallurgical coal
Metallurgical coal, commonly called coking coal in industry, is a critical raw material for traditional steelmaking and many heavy industries. Unlike thermal coal used mainly for power generation, metallurgical coal…
Semi-anthracite
Semi-anthracite is a distinct rank of coal that occupies a middle ground between high-grade anthracite and the more common bituminous coals. It combines many of the advantageous physical and chemical…
Anthracite
Anthracite is the highest rank of coal, prized for its high-grade energy content and distinctive physical properties. This dense, hard variety of coal has played an important role in industry,…
