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.

Concentration - LKAB

When the concentration of the ore is complete, it is time for pelletisation. Concentration means the beneficiation of finely ground ore by separation into a concentrate of iron ore powder with a very high level of purity. Flotation is a chemical process for particle separation.
