Magnetite & Lodestone Mineral Photos, Uses, Properties

Use of Magnetite as an Ore of Iron. 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.

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 (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the

Magnetite an overview ScienceDirect Topics

Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral not only because it is magnetic.The formula could be written as Fe 2 + Fe 3 + 2 O 4, which more precisely designates one of its peculiarities.It contains both ferrous (Fe 2 +) and ferric (Fe 3 +) ions, implying synthesis, growth, and stability within an environment where oxidized and reduced states of iron are present and maintained.

MAGNETITE (Iron Oxide)

Magnetite is an oxide of iron (as is hematite).It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite.
