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.

The Pelletizing Process. The production of iron ore pellets from fines to finished product can differ based on a variety of factors. As such, it's important to note that the process described here is a generalized approach subject to many variations. In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning
