SPONGE IRON – Lloyd’s Metals
The process entails a direct reduction of the iron ore (i.e. removal of oxygen from the ore) in solid state to metalize the ore at a ‘critical’ temperature to make this possible. The basic reduction reactions in a coal based DRI process is as follows C+ O2 = CO2 CO2 +C = 2CO 3Fe2O3 + CO = 2Fe3O4 + CO2 Fe3O4 + CO = 3FeO + CO2 FeO + CO = Fe + CO2

2020-3-3 Sponge iron is obtained when iron ore (generally lump haematite iron ore, pellets) is reduced to metallic form in solid state. Since there is no melting, external shape of raw material is retained. Colour changes from red to black. The true density changes from about 3.5 to 4.4 g/cm 3. The true density of pure iron is 7.8 g/cm 3.
