Learn More | What is PCI (Pulverised Coal Injection) Extraction?
PCI coal is a type of metallurgical coal that plays a crucial role in the steelmaking process. It is used as a supplementary source of carbon and heat in blast furnaces to facilitate the production of molten iron, which is then further processed into steel. PCI coal is finely ground and injected into the blast furnace in a powdered form, where it ignites and helps reduce iron ore into molten iron.
