  • Sponge Iron

    MANUFACTURING PROCESS. In the DRI plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps/pellets) with a carbonaceous material like coal or lignite. The reduction is carried out in a rotary Kiln (which is inclined and rotates at a predetermined range of speed) at a stipulated temperature ( 850 °C – 1050°C).
