Coal based Direct Reduction Rotary Kiln Process IspatGuru

The main raw materials for the production of DRI by the rotary kiln process are (i) sized graded iron ore or iron ore pellets, (ii) non-coking coal, and (iii) dolomite in small quantities to scavenge the sulphur. Iron ore of the right quality is the basic input for the coal based direct reduction process.

Direct reduced iron Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting
