Iron Ores
Magnetite gets its name because it has the (rare) property of being magnetic. More to the point, magnetism got its name because there was magnetite, possibly named after the place it was first found, for example ""Magnesia" in present day Turkey. Magnetite melts at 1535 °C (2795 °F) and has a density around 5.2 g/cm 3.

Iron Ore
The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Hematite is an iron oxide mineral. It is non-magnetic and has colour variations ranging from steel silver to reddish brown. Pure hematite contains 69.9% Fe by molecular weight. It has been the dominant iron ore mined in Australia since the early 1960s.
