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.

Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction.
