Iron Ore Statistics and Information U.S. Geological Survey
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.

From mine to port LKAB
Our iron ore is mined both above and below ground. The vast majority of our mining takes place several hundred metres underground, in the mines in Kiirunavaara (Kiruna) and Malmberget (Gällivare), which are the world’s two largest underground iron ore mines. In Svappavaara, the ore is mined in the Leveäniemi surface mine.
Mineral Deposit » Geology Science
Iron Ore Mineral. Secondary minerals. Secondary minerals are those that form at or near the ground surface as mineral deposits are exposed by erosion or mining and weathered by ground waters, surface waters, and the atmosphere. Depending upon their compositions and solubilities, secondary minerals can be beneficial, by restricting access of
Geophysical Methods Geological Survey of Ireland
The method operates by emitting a percussive force to the ground, producing seismic waves which travel through the subsurface, reflecting back or refracting each time a structure of geological boundary is encountered. Thus from this, the depth and shape of underground structures can be interpreted from seismic profiles.
How do we extract minerals? U.S. Geological Survey
Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.
