The process of sponge iron manufacturing involves removal of oxygen from iron ore. When that happens, the departing oxygen causes micro pores in the ore body, turning it porous. When the eventual product is observed under a microscope, it resembles ab structure, which looks spongy in texture. Hence the name sponge iron.
Direct Reduced Iron DRI Production Plant NIPPON STEEL ENGINEERING . Basic Concept or Summary S 16 u A direct reduced iron DRI production plant is a shaft reduction furnace to produce DRI with large metal iron content by directly reducing iron ore or iron ore pellets with reducing gases. u While the produced DRI is mainly used as the raw material of electric steelmaking, it is

Creating steel from low grade iron ore requires a long process of mining, crushing, separating, concentrating, mixing, pelletizing, and shipping. The process of mining low grade iron ore, or taconite, requires massive resources. Heavy industrial mining equipment, expansive mines, and a skilled labor pool are all required. The equipment used includes diamond bit rotary drills, hydraulic

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 8001200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds
following advantages sponge iron production is rising. Pelletized iron ore or natural lump ore are used in direct reduction process. Exceptionally in the fluidized bed process sized iron ore particles are used. Few selected ores are suitable for direct reduction process. Sponge iron is produced in a powdered form so, it acts as a good raw material that can very well mixed with other metals
