  • Introduction to Iron ore Pellets and Pelletizing processes

    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 (0.074 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.

    50 Iron Ores and Iron Oxide Materials Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the forma- tion of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.
