The LabMag mine is a proposed iron mine near Schefferville in northern Quebec, Canada. LabMag is one of the largest iron ore reserves in the world, having estimated reserves of 5.74 billion tonnes of ore grading 29.4% iron metal. [1]
Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining, and is therefore considered an ore.
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe
3O
4, 72.4% Fe), hematite (Fe
2O
3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe).
Ilmenite is a titanium-iron oxide mineral with the idealized formula FeTiO
3. It is a weakly magnetic black or steel-gray solid. Ilmenite is the most important ore of titanium and the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.
Taconite is a variety of iron formation, an iron-bearing sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate. The name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) – son of Newton Horace Winchell, the Minnesota State Geologist – during their pioneering investigations of the Precambrian Biwabik Iron Formation of northeastern Minnesota. He believed the sedimentary rock sequence hosting the iron-formation was correlative with the Taconic orogeny of New England, and referred to the unfamiliar and as-yet-unnamed iron-bearing rock as the 'taconic rock' or taconyte.
Vale S.A., formerly Companhia Vale do Rio Doce is a Brazilian multinational corporation engaged in metals and mining and one of the largest logistics operators in Brazil. Vale is the largest producer of iron ore and nickel in the world. It also produces manganese, ferroalloys, copper, bauxite, potash, kaolin, and cobalt, currently operating nine hydroelectricity plants, and a large network of railroads, ships, and ports used to transport its products.
Schefferville is a town in the Canadian province of Quebec. Schefferville is in the heart of the Naskapi and Innu territory in northern Quebec, less than 2 km from the border with Labrador on the north shore of Knob Lake. It is located within the Caniapiscau Regional County Municipality and has an area of 24.76 square kilometres (9.56 sq mi). Schefferville completely surrounds the autonomous Innu community of Matimekosh, and it abuts the small community of Lac-John Reserve. Both of the latter communities are First Nations Innu reserves. Schefferville is also close to the Naskapi reserved land of Kawawachikamach.
Sherman Mine is a closed open pit mine in Temagami, Ontario, Canada. It was a major producer of iron ore, starting production in 1968 and closing in 1990. Sherman was the largest open pit mine in Temagami, consisting of seven open pits known as the East Pit, South Pit, North Pit, West Pit and the Turtle Pits. The mine was discovered in the early part of the twentieth century, however interest was limited as a result of silver and gold discoveries in northeastern Ontario. While the Ontario government offered bounties to producers of iron ore, there was little interest in putting any iron mine into production as a result of cheaper Mesabi Range ores from the US and the Great Depression. It was only in the 1950s that Canadian steel producers started to investigate domestic supplies of iron ore. This would lead to the re-opening of the Moose Mountain Mine and development of the Adams, Sherman and Bruce Lake mines in Northern Ontario. The Sherman Mine operated in tandem with the Adams Mine in Kirkland Lake, and when the Adams Mine approached exhaustion of its economic ore reserves, the decision was made to also close the Sherman Mine. The surface infrastructure was removed and the site was abandoned. The waste piles are currently used by the municipality as a source of crushed stone for road works.
Cleveland-Cliffs Inc., formerly Cliffs Natural Resources, is a Cleveland, Ohio-based company that specializes in the mining, beneficiation, and pelletizing of iron ore, as well as steelmaking, including stamping and tooling. It is the largest flat-rolled steel producer in North America.
The mineral industry of Russia is one of the world's leading mineral industries and accounts for a large percentage of the Commonwealth of Independent States' production of a range of mineral products, including metals, industrial minerals, and mineral fuels. In 2005, Russia ranked among the leading world producers or was a significant producer of a vast range of mineral commodities, including aluminum, arsenic, cement, copper, magnesium compounds and metals, nitrogen, palladium, silicon, nickel and vanadium.
Mining is an important industry in Pakistan. Pakistan has deposits of several minerals including coal, copper, gold, chromite, mineral salt, bauxite and several other minerals. There are also a variety of precious and semi-precious minerals that are also mined. These include peridot, aquamarine, topaz, ruby, emerald, rare-earth minerals bastnaesite and xenotime, sphene, tourmaline, and many varieties and types of quartz.
The Muncelu Mic mine was a large open pit mine in the western of Romania in Hunedoara County, 16 km southeast of Simeria and 387 km north-west of the capital, Bucharest. Muncelu Mic represents one of the largest iron ore reserves in Romania having estimated reserves of 6.5 million tonnes of ore. When it was operational it produced around 200,000 tonnes of iron ore/year. The mine also has a gold and silver reserves of around 5.4 million tonnes grading 1g/t gold and 8g/t silver resulting 173,000 oz of gold and 1.38 million oz of silver.
The Ghelari mine was a large open pit, also an underground iron ore mine in the western of Romania in Hunedoara County, 20 km south-west of Hunedoara and 411 km north-west of the capital, Bucharest. Ghelari represents one of the largest iron ore reserves in Romania having estimated reserves of 14 million tonnes of ore. The mine produced around 200,000 tonnes of iron ore/year.
Oil and gas dominate the extraction industries of the Republic of the Congo, also referred to as Congo-Brazzaville. The petroleum industry accounted for 89% of the country’s exports in 2010. Among African crude oil producers in 2010, The Congo ranked seventh. Nearly all of the country's hydrocarbons were produced off-shore. The minerals sector is administered by the Department of Mines and Geology. Presently no major mining activities are underway, although there are some small-scale domestic operations. However, the country does have numerous large-scale undeveloped resources. The country has recently attracted a strong influx of international companies seeking to tap into the vast mineral wealth.
Mining in North Korea is important to the country's economy. North Korea is naturally abundant in metals such as magnesite, zinc, tungsten, and iron; with magnesite resources of 6 billion tonnes, particularly in the North and South Hamgyong Province and Chagang Province. However, often these cannot be mined due to the acute shortage of electricity in the country, as well as the lack of proper tools to mine these materials and an antiquated industrial base. Coal, iron ore, limestone, and magnesite deposits are larger than other mineral commodities. Mining joint ventures with other countries include China, Canada, Egypt, and South Korea.

Balmoral South represents one of the largest iron ore reserves in Australia and the world, having estimated reserves of 859 million tonnes of ore grading 22.6% MagFe and 31.2% Fe. It is currently owned by Clive Palmer's company Mineralogy.
