Hematite Iron Ore - Iron Ore

 · There are several types of iron ore. The most commonly mined type is Hematite, particularly in Brazil, China and Australia, where it makes up 96% of all exports. The ore itself is a deep, brownish red colour which is where the name comes from (Haima is the Greek word for blood) and has a chemical formula of Fe2O3 and is also known as Ferric Oxide.

Iron Ore Statistics and Information

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.

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.

Difference Between Magnetite and Hematite l Magnetite vs ...

 · Magnetite and hematite are important oxides of iron. Though there are several differences between them, the key difference between magnetite and hematite is that the iron in magnetite is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. Magnetite is black in colour, but hematite has
