The Chinese steel makers then mix the mill scale with the low quality iron ore and prepare it for feed to a sinter plant, whereas the iron ore is mostly less than 60% Fe and the mill scale is around 70% Fe. How much they add is dependent on their steel making processes.

But, the mill scale can be reduced by suitable reductant to produce DRI (Direct reduced iron) or metallized iron ore. During the direct reduction process mill scale or iron ore has been reduced in a solid-state at a high temperature below the melting point (T < 1300 °C) in the presence of suitable reductants (solid or gaseous) to give metallized iron ore or DRI.
