An Optimal Route for the Preparation of Metallized Composite Pellets

While the pelletization process takes care of the fines, the pre-reduction step reduces the overall energy requirement. Pelletization is an agglomeration technique typically used in ironmaking industries to produce iron-ore pellets utilized as blast furnace feedstock [11,12,13,14,15]. However, the pelletization of ilmenite concentrate isThe 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 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. The goals stemming from the final reduction process are drawn back through the pelletization process to present a clear rationale for why each material can be used to control the pellet quality. {Iron Ore Pelletization: Part II.
