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

The pelletizing process is a process which contains numerous subprocesses, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments: 1) The iron ore is crushed and the waste rock is removed. About 85 % of the particles should be less than 44 μm (in length, width, or height).
