The pelletizing process is a process which contains numerous sub-processes, 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).
