Hematite

Hematite is the principle ore of iron used in the manufacture of steel.

Chemical Formula: Fe₂O₃

Other names: Iron(III) oxide, Ferric Oxide, Red Iron Ore, Specularite, Oligiste

Layman's explanation: Hematite comes from the Greek word haimatitis for blood-red. However, the color of the mineral hematite ranges from black to brick red and is a major ore of iron. The mineral was used as a source to make iron by early Native Americans to produce celts, a hatchet like apparatus. Iron oxide is soluble in acids but insoluble in water. Hematite commonly occurs with quartz, calcite, albite, biotite, barite, pyrite, magnesite, and magnetite and the largest hematite samples are bodies that are of sedimentary origin, bedded, or are metamorphosed sedimentary deposits. There are several types of hematite and each has its own unique name and some are considered to be rare. Major processing countries of hematite are Brazil, Italy, England, Australia, Mexico and the United States.
