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).

Ore: Ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit. An older definition restricted usage of the word ore to metallic mineral deposits, but the term has expanded in some instances to include nonmetallics. Although more than 2,800 mineral species

Metals and Ores • Metal ores are naturally occurring materials that can be profitably mined • Whether or not a mineral deposit is considered an ore depends on its chemical composition, percentage of extractable metal, and the current market value of the metal • Metallic ore deposits can originate by

An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining ; they are then refined (often via smelting ) to extract the valuable element, or elements.

most minerals are metallic, however, the term "metallic mineral" refers to a mineral that is used as an ore for the metal in the mineral. For example, Covellite - Wikipedia is considered a "metallic mineral" and is a source of copper.

The terms ore mineral and mineral deposit were originally applied only to minerals and deposits from which metals are recovered, but present usage includes a few nonmetallic minerals, such as barite and fluorite, that are found in the same kinds of deposit as metallic minerals.

Mineral processing—sometimes called ore dressing, mineral dressing, or milling—follows mining, and it prepares the ore for extraction of the valuable metal in the case of metallic ores and produces a commercial end product from products such as iron ore and coal.

However, since 1990, no metal has been made from any ore mined in the state. This situation is due to changing world market conditions, the discovery of commercial deposits elsewhere in the world, and increasing labor, energy, and environmental costs in the United States. ...
