Summary. In this chapter, we learned that three main ferrous burden materials are used in BF operation; lump ore, sinter, and pellets. The types of iron ores used to produce these three ferrous charge materials and the related production methods were described. The various analysis methods used to determine the quality of the BF charge ...

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.

In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning The mixing step sets the stage for the remainder of the process, creating a homogeneous mixture that will allow for a uniform product to be created. In order to pelletize iron ore fines and/or concentrate, a binder is needed.

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.
