Iron Ore Pelletizing Process: An Overview IntechOpen

2018-07-11  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 low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

Iron Ore Pelletizing Process: An Overview

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.

What Are Iron Ore Pellets?

The process is considered more efficient than making use of iron ore powder, which does not allow the hot air to freely circulate and warm the ore to a uniform temperature. For this reason, the pellets are often preferable to fine iron ore products, since the ability to achieve that balance in temperature is somewhat limited with the fine ore products.
