Blast Furnace – Basic Oxygen Furnace (BF-BOF): This is the dominant steel production route in the iron and steel industry, involving the reduction of iron ore to pig iron in the blast furnace. BF-BOF operation relies almost entirely on coal products, emitting ~70% of CO2 in the integrated plant (BF iron making).

This is a coal-based reduction technology, applicable to both steel mill waste and iron ore fines, with coal as a C-reductant agent. The reduced iron can be fed to a BF or directly into a melting process. If exposed to air for a long time, the metallic iron reoxidizes into iron oxide, deteriorating its quality.

Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called "pellets." Bentonite clay has traditionally been used as a binder to make …
