    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 pre-determined range of speed) at a stipulated temperature ( 850 °C 1050°C).Iron Sponge Process an overview ScienceDirect Topics,8.5.1 Iron sponge process. An example of a hydrogen sulfide scavenger process is the iron sponge process (also called the dry box process), which is the oldest and still the most widely used batch process for sweetening of natural gas and natural gas liquids (Anerousis and Whitman, 1984). The process was implemented during the 19th century and
