Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh ( mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

Abstract The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.

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).
