Coal & steel | World Coal Association

Steel is produced via two main routes: the blast furnace-basic oxygen furnace (BF-BOF) route and electric arc furnace (EAF) route. The BF-BOF route is used for 71% of steel produced, whilst the EAF route accounts for 29% of steel produced. The key difference between these routes is the material used to produce the steel and the plant configuration.
