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 …

This document discusses the need for lean iron ore beneficiation in India to utilize low-grade iron ore deposits. It notes that India has large reserves of iron ore but current mining practices only utilize ore above 58% Fe. Beneficiating low-grade ore deposits through finer grinding and pelletization could increase reserves and improve economics.

DRI is produced by reducing iron ore to a purity of 90-97% iron through a process using reducing gases like hydrogen and carbon monoxide at high temperatures below iron's melting point. In an RHF, iron ore and carbon pellets are heated on a rotating hearth through burners as the iron oxides are reduced over 6-12 minutes to produce DRI pellets.
