Terence Bell. Updated on August 21, 2020. 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.

PCI substitute. While it may be possible to use lowcost agricultural biomass for the same purpose, the higher alkali and alkaline earth metal compound contents, as well as the content of phosphorus compounds in agricultural biomass have made biocarbon from it to be less preferred as a potential replacement for the thermal coal used for PCI.

2006, the main area for increased PCI consumption is still thought to be in Asia, particularly China and India (Boyle, 2006). The construction of new BFs and Asian steel producers utilising PCI coal at higher consumption rates will drive the demand for PCI coal. New BFs will be preferred over scrapbased minimills wherever steel demand is large,
