Iron Ore Pelletizing Process: An Overview

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. This chapter …

The efficient operation of a blast furnace requires burden materials with high softening temperatures and a narrow softening–melting range. This leads to the formation of a thinner cohesive zone in the lower part of the furnace, which improves permeability. In this study, softening–melting tests were conducted on pellets with different levels of basicity, combined …
