Iron Ores (Hematite and Magnetite)
Magnetite is a mineral that is transparent (not transparent). It is found primarily in sedimentary rocks. However, it is occasionally found in large quantities in beach sand. Magnetite is primarily used to extract iron in the form of pig iron or sponge iron. This produced iron is then used to make steel. Magnetite is also used as a catalyst.

Magnetite: The Future of Iron Ore
Steel's Secret: Infinite Recyclability Made up primarily of iron ore, steel is an alloy which also contains less than 2% carbon and 1% manganese and other trace elements. While the defining difference might seem small, steel can be 1,000x stronger than iron. However, steel's true strength lies in its infinite recyclability with no loss of quality.

Iron Ore to Sintering to Steelmaking
The USGS defines iron ore as 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). It's a major ingredient in steel. Here's what the USGS has to say about iron ore:

Iron Ores (Hematite and Magnetite)
An ore is a mineral deposit that contains a metal that can be extracted using existing technological methods. Iron can be extracted from two types of iron ores: Magnetite and hematite. Magnetite is composed of iron in the form of Fe 3 O 4. Hematite is a mineral that contains iron in the form of Fe 2 O 3.
