Low-carbon production of iron and steel: Technology options, economic
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 CO 2 in the integrated plant (BF iron making). Hot iron is then charged to a ...
