Solved Direct Reduced Iron is produced in a rotary kiln.

Direct Reduced Iron is produced in a rotary kiln. Iron ore is fed to the kiln, along with coal as reductant (to reduce FeOx to Fe) as well as a small amount of dolomite which acts as sulphur collector. Reduction occurs at roughly 1000°C within the bed and CO gas rises as the solid iron is produced, i.e. no liquid is present.
