bitumiinihiili
Bitumiinihiili, also known as coking coal or metallurgical coal, is a type of coal with specific qualities that make it suitable for use in the production of coke, a crucial material in the steelmaking process. It is characterized by its high carbon content, low ash, and low sulfur content, which are essential for producing high-quality coke. During the coking process, bitumiinihiili is heated in the absence of air at high temperatures, driving off volatile components and leaving behind a hard, porous substance called coke. This coke then acts as a fuel and a reducing agent in blast furnaces to smelt iron ore into iron.
The formation of bitumiinihiili occurs under specific geological conditions, typically involving the burial of ancient plant
