Abstract: The article presents a study on the impact of iron ore pellet size on its properties and microstructure. It cites that pellets properties and microstructure depend on raw material mix proportion. Also, reduction and oxidation process occur under various conditions due to pellet size differences. Pellets size from +eight to -12 mm have good strength with lower reduction degradation index (RDI) which are significantly affected by hematite, magnetite, porosity, pore density and size and slag phase.
