The process of iron making is the reduction of iron ore to produce iron. Iron ore normally contain gangue materials such asSiO2, Al2O3 along with S and P. Removal of these impurities is done by combining the gangue materials with CaO and / or MgO to form slag which consists of low melting point complex compounds such as calcium silicate ...

Magnetite is a lower grade ore (25-40 per cent iron) which needs extra processing. This processing, however, produces ore with more iron content, fewer impurities and less waste rock (known as gangue) than hematite. It's also, as the name suggests, magnetic. That makes it possible to efficiently separate iron from waste rock using magnets.
