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, LuossavaaraKiirunavaara AB (LKAB) has produced over 950Mt of ore, yet only one third of the original ore body has been extracted.
Magnetite ore is a ferromagnetic material, with the chemical formula Fe3O4, and is one of several types of iron is a ubiquitous mineral in many parts of the world, including Australia, the USA, Canada, South Africa, Mozambique and many other countries across most of the world''s continents.
Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturallyoccurring minerals on Earth.

More than 90% of South Australia''s iron ore is magnetite located in several prospective areas of the state, stretching from the Eyre Peninsula to the Braemar province and the Far North.; Approximately million tonnes of magnetite was produced in South Australia in 2018 for domestic use and export while there are a number of magnetite projects in various stages of development.
Jun 06, 2006· Russia''s sole producer of vanadium raw material is the Kachkanar iron ore mining complex in Sverdlovsk oblast in the Urals that mines titaniferous magnetite (Levine, 1996).
With all of hematite''s many varieties, it is natural that some of them can be easily confused with other metallic minerals. All of the hematite varieties though, exhibit the same distinctive red to redbrown streak when scratched across a rough hard surface, which should serve to distinguish hematite from similarappearing minerals.
Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The principle ores of iron are hematite, (70% iron) and magnetite, (72% iron). Taconite is a lowgrade iron ore, containing up to 30% magnetite and hematite. Relation to Mining
All magnetite ores from South Australia produce concentrates with low levels of deleterious elements inclusive of those deposits with relatively coarse grinds in the range 75–125 µm. Magnetite concentrate grades range from 65 to 70% Fe with the variation in iron grade largely sympathetic according to .
Magnetite Mines Limited is a developmentstage company advancing the Razorback High Grade Iron Ore Concentrate Project located in the Braemar, Australia''s emerging iron ore mining region.
Magnetite Mines Ltd says it has entered into an exclusivity agreement with ore sorting technology company NextOre to use its leadingedge magnetic resonance ore sorting technology for preconcentration of magnetite and iron ore projects.
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 highquality magnetite have been mined in New Jersey and Vermont.
