The induration process for green pellets involves 4 main stages: (1) drying, (2) preheating, (3) heating and (4) cooling. In the drying stage (105260°C), water is removed from the pellet in a controlled process to avoid cracking. During preheating (260845°C), oxidation of the magnetite and decomposition of carbonates occur.

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).
