Principles of Extractive Metallurgy - Indian Institute of Technology Madras

• Carbothermic reduction of iron ore (Hametite) in blast furnace is a well known process. Overall process is written as: •Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag (liquid) + waste gas (CO,CO2,N2) •Iron ore contains Fe2O3, along with gangue materials such as SiO2, Al2O3.

The unmelted iron ores still contain non-reduced iron oxides. An unfavourable accumulation of ores at the contact points can also make gas flow difficult and thus leave non-reduced iron ore behind. At the latest, however, when the melting process occurs in the deeper and hotter zones of the blast furnace, iron ores can be almost completely reduced.
