In the third stage further decarburization ( wt% C) was achieved by increasing the FeO content of slag to 25 wt%. Eventually, in the last phase, a carbon level of wt% was maintained by reducing the amount of oxidizers in the feed, and keeping FeO of slag around 20 wt%.
Mill scale is an iron oxide waste generated during steelmaking, casting and rolling. 35%Fe 2 O 3 . sinter mix. ironmaking units. The aim of this study is to determine the effect of mill scale on pellet properties. Detailed laboratory basket trials were conducted using up to 40% of mill scale in the pellet mix.
Mill scale is a magnetic material consisting of iron in a typical range of 9395%. Hence, the chemical composition of mill scale is similar to hematite; magnetite or wüstite.

specific production of mill scale is approximately 35–40 kg per ton of produced steel [3]. Moreover, the total iron content of mill scale is between 65% and 70% [3, 4].
carbon steel, the tertiary scale formed at high temperatures usually consists of three iron oxide phases, the inner wüstite (FeO), magnetite (Fe 3 O 4) and the outer layer hematite (aFe 2 O 3)15. The thickness of these three phases will be different with the changes of oxidation conditions, steel compositions and surface finish3,6.
As mill scale contains mainly FeO and Fe3O4, any minor amount of its addition in pellet can provide in situ heat and enhance diffusion bonding and sintering. In this study, the mill scale generated in steel plant is added as magnetite input in hematite pellet both in acidic and in basic condition.
