The Sanheming mine is a large iron mine located in Inner Mongolia in China. Sanheming represents an estimated reserve of 167 million tonnes of ore, grading 34.8% iron metal. [1]
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).
The Iron Range is collectively or individually a number of elongated iron-ore mining districts around Lake Superior in the United States and Canada. Much of the ore-bearing region lies alongside the range of granite hills formed by the Giants Range batholith. These cherty iron ore deposits are Precambrian in the Vermilion Range and middle Precambrian in the Mesabi and Cuyuna ranges, all in Minnesota. The Gogebic Range in Wisconsin and the Marquette Iron Range and Menominee Range in Michigan have similar characteristics and are of similar age. Natural ores and concentrates were produced from 1848 until the mid-1950s, when taconites and jaspers were concentrated and pelletized, and started to become the major source of iron production.
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines and coal mines.
The following is a list of Registered Historic Places in Iron County, Michigan. The list includes 79 structures and historic districts that are significant for their architectural, historical, or industrial/economic importance.
The mining industry in India is a major economic activity which contributes significantly to the economy of India. The gross domestic product (GDP) contribution of the mining industry varies from 2.2% to 2.5% only but going by the GDP of the total industrial sector, it contributes around 10% to 11%. Even mining done on small scale contributes 6% to the entire cost of mineral production. Indian mining industry provides job opportunities to around 700,000 individuals.
Mining in Iran is still under development, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of potential reserves worth $770 billion in 2014. Mineral production contributes only 0.6 percent to the country's GDP. Add other mining-related industries and this figure increases to just four percent (2005). Many factors have contributed to this, namely lack of suitable infrastructure, legal barriers, exploration difficulties, and government control.

Elcor is a ghost town, or more properly, an extinct town, in the U.S. state of Minnesota that was inhabited between 1897 and 1956. It was built on the Mesabi Iron Range near the city of Gilbert in St. Louis County. Elcor was its own unincorporated community before it was abandoned and was never a neighborhood proper of the city of Gilbert. Not rating a figure in the national census, the people of Elcor were only generally considered to be citizens of Gilbert. The area where Elcor was located was annexed by Gilbert when its existing city boundaries were expanded after 1969.
