Uses of Magnetite . Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.

Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron (II) and iron (III). Its empirical formula is Fe 3 O 4, and it is often expressed as iron (II,III) oxide. In the past, it has been called ferrous–ferric oxide and triiron tetraoxide. Magnetite is found in igneous, metamorphic, and sedimentary ...

Iron Ores (Hematite and Magnetite) Iron is a metal from the periodic table's first transition series and group 8. It is the most common element on Earth by mass, just ahead of oxygen (32.1 % and 30.1 %, respectively), forming much of the Earth's outer and inner cores. It is the fourth most abundant element in the crust of the Earth.
