Iron Ore Pelletizing Process: An Overview

Jul 10, 2017The 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 Get price

and Abrasion Index (AI) for the iron ore pellets used in furnace reduction process are 70wt% for the TI value and 5wt% for the AI value [2]. It follows from Table 1 that the TI values of Muko ores are between 88wt% and 93wt%, which is signiﬁcantly higher than the stipulated 70wt%. Therefore, the ores from all Muko deposits can be Get price
