After iron ore is mined it is crushed into a powder then injected into a blast furnace. Under the extreme temperatures the ore melts and since iron is more dense than the impurities, it sinks to the bottom. This leaves a film of "slag" (impurities) on top.

Magnetite and hematite are iron oxides; however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed. The second step in the process is calcination or roasting of the ore, which removes certain impurities, carbon dioxide and other substances.

Impurities in Iron Ores. There are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable.
