Integrated steel mills that utilize this process also have auxiliary operations in the form of coke and sinter/pellet plants. According to the American Iron and Steel Institute, coke is the most important raw material fed into the blast furnace (Valia, 2015). It is used to reduce iron ore to iron. High quality coal is heated in an oxygen-
