Kiruna Iron Ore Mine - Mining Technology | Mining News and ...
With an ore body 4km long, 80m thick and reaching a depth of 2km, LKAB's Kiruna is the world's largest, most modern underground iron ore mine. Since mining began at the site over 100 years ago, Luossavaara-Kiirunavaara AB (LKAB) has produced over 950Mt of ore, yet only one third of the original ore body has been extracted.
The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4). Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers.

Magnetite is widely distributed usually with octahedral, or spherical, morphology, in igneous and metamorphic rocks. Magnetite is also found in limestones, in fumerolic deposits, and in living forms. For the latter the mineral plays some very important role, which we highlight in Section 8.04.3.3.2.

Magnetite: The mineral Magnetite information and pictures
Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.
Magnetite: Mineral information, data and localities.
Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

Magnetite: The Future of Iron Ore - Visual Capitalist
· Magnetite ore, long the leading source of domestic iron supply in North America, Europe and China, is now increasingly relevant across the globe. The perception that magnetite ore is an inferior substitute to hematite ore is now firmly changing. As easily accessibly, economic hematite deposits become rarer, magnetite ore will continue to emerge as an […]

Where Is Magnetite Generally Found? | Reference.com
Magnetite is found in large quantities in North and South America, Europe, and New Zealand. Magnetite is eroded into rivers and carried to the beach, where it accumulates in sand. It is then concentrated via wave action and currents. In the United States, large quantities of high-quality magnetite have been mined in New Jersey and Vermont.

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.
