Iron oxide ores taken out from the Earth are allowed to absorb carbon by a reduction process. In this natural reduction, as the iron ore is warmed up with carbon, it results in a surface with hole marks, hence the name "Sponge Iron". The commercial process is a solid solution reduction, also called Direct-Reduced Iron (DRI).
