More often, magnetite is dispersed throughout a rock as microscopic crystals that form along the edges of iron-bearing minerals such as biotite, amphiboles and pyroxenes. In this dispersed form, it seldom constitutes enough of the rock's volume to be detected by a hand held magnet, although the rock may exhibit a paleomagnetic signature that can be detected by sensitive instruments.

Hematite | Fe2O3 - PubChem

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4 ) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial .
