USGS Minerals Information Iron Ore
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.

The important vanadium minerals are patronite (VS 4), carnotite [K 2 (UO 2) 2 (VO 4) 2], and vanadinite, [Pb 5 (VO 4) 3 Cl]. Ore deposits mined solely for vanadium are rare because much of the vanadium in igneous rocks occurs in the relatively insoluble trivalent state, substituting for ferric iron in ferromagnesium silicates, magnetite (an
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Iron Ore ~ Learning Geology
The iron ore deposits are found in sedimentary rocks. They are formed by the chemical reaction of iron and oxygen mixed in the marine and fresh water. The important iron oxides in these deposits are hematite and magnetite. These are ores from where iron is extracted.

The rocks are "banded" because the iron minerals deposited in alternating bands with silica and sometimes shale. The banding might have resulted from seasonal changes in organism activity. The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. General Geology Articles about
Wisconsin Geological Natural History Survey Mining Iron
Iron ore can be defined on the basis of its iron content into low grade ore (taconite), which commonly contains 25 to 35% iron, and high grade ore, which contains 50 to 70% iron. Iron bearing ore minerals include oxides, carbonates, silicates, and, in some cases, sulfides.
ore National Geographic Society
Ore is a deposit in the Earths crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.Copper is also used in construction.
Ore mining Britannica
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
Geology, Prospecting and Exploration for Iron Ore Deposits
Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earths crust.
