Hematite stone is the main mineral in Iron and is mined in locations all around the world. The most notable places being Australia, Brazil, Canada, Chile, China, Cuba, England, Germany, India, Mexico, Spain and Russia.
Hematite does not contain iron in natural state. When it is ground down into a powder and mixed with a small quantity of iron then it can be magnetised to a limited strength which is due the size of the item formed and the quantity of iron it is mixed with.
The primary mineral would be... hematite. Many other minerals could be present, to one degree or another, including magnetite, pyrite, quartz, etc.
A: Magnetite increases the density of most mixtures in which it is present. This property allows magnetite to be used in the manufacture of heavy concrete, water filtration, coal mining, landscaping and production of certain ironbased chemicals.

Hematite (AE) or haematite (BE) (sometimes missspelled as hemitite) is the mineral form of Iron (III) oxide, (Fe2O3), one of several iron oxides, formed from Magnetite. Magnetite is the most magnetic of all the naturally occurring minerals on Earth, and these magnetic properties led to its use as an early form of magnetic compass.

Chemical Formula: Fe4O3(OH)6. Hydrated oxide of iron, often impure. The analyses of limonite range between wide limits, largely because of the great quantities of impurities mixed with it. The principal impurities are clay, sand, phosphates, silica, manganese compounds and organic matter.
Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its ironcontent.
