Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Rio Tinto Group is a British-Australian multinational company that is the world's second largest metals and mining corporation. It was founded in 1873 when a group of investors purchased a mine complex on the Rio Tinto, in Huelva, Spain, from the Spanish government. It has grown through a long series of mergers and acquisitions. Although primarily focused on extraction of minerals, it also has significant operations in refining, particularly the refining of bauxite and iron ore. It has joint head offices in London, England and Melbourne, Australia.

Mining in Australia has long been a significant primary sector industry and contributor to the Australian economy by providing export income, royalty payments and employment. Historically, mining booms have also encouraged population growth via immigration to Australia, particularly the gold rushes of the 1850s. Many different ores, gems and minerals have been mined in the past and a wide variety are still mined throughout the country.
Romania ranks tenth in the world in terms of the diversity of minerals produced in the country. Around 60 different minerals are currently produced in Romania. The richest mineral deposits in the country are halite.
Lundin Mining Corporation is a Canadian company that owns and operates mines in Sweden, United States, Chile, Portugal and Brazil that produce base metals such as copper, zinc, and nickel. Headquartered in Toronto, the company was founded by Adolf Lundin and operated by Lukas Lundin. While it was incorporated to pursue an interest in a diamond mine in Brazil, the company re-structured and raised funds to develop the Storliden mine in Sweden. It purchased the Swedish Zinkgruvan Mine from Rio Tinto and then merged with Arcon International Resources for its Galmoy Mine in Ireland and with Eurozinc for its Neves-Corvo mine in Portugal. The company subsequently purchased and operated the Eagle mine, Candelaria mine, and Chapada mine.
Mining in Afghanistan was controlled by the Ministry of Mines and Petroleum, prior to the August 15th takeover by the Taliban. It is headquartered in Kabul with regional offices in other parts of the country. Afghanistan has over 1,400 mineral fields, containing barite, chromite, coal, copper, gold, iron ore, lead, natural gas, petroleum, precious and semi-precious stones, salt, sulfur, lithium, talc, and zinc, among many other minerals. Gemstones include high-quality emeralds, lapis lazuli, red garnet and ruby. According to a joint study by The Pentagon and the United States Geological Survey, Afghanistan has an estimated US$1 trillion of untapped minerals.
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.
The second-largest mineral industry in the world is the mineral industry of Africa, which implies large quantities of resources due to Africa being the second largest continent, with 30.37 million square kilometres of land.With a population of 1.4 billion living there, mineral exploration and production constitute significant parts of their economies for many African countries and remain keys to economic growth. Africa is richly endowed with mineral reserves and ranks first in quantity of world reserves for bauxite, cobalt, industrial diamond, phosphate rock, platinum-group metals (PGM), vermiculite, and zirconium.
Mining is the biggest contributor to Namibia's economy in terms of revenue. It accounts for 25% of the country's income. Its contribution to the gross domestic product is also very important and makes it one of the largest economic sectors of the country. Namibia produces diamonds, uranium, copper, magnesium, zinc, silver, gold, lead, semi-precious stones and industrial minerals. The majority of revenue comes from diamond mining. In 2014, Namibia was the fourth-largest exporter of non-fuel minerals in Africa.
The following outline is provided as an overview of and topical guide to mining:
The mineral industry of Peru has played an important role in the nation's history and been integral to the country's economic growth for several decades. The industry has also contributed to environmental degradation and environmental injustice; and is a source of environmental conflicts that shape public debate on good governance and development.
Resources are classified as either biotic or abiotic on the basis of their origin. India contains a multitude of both types of resource and its economy, especially in rural areas, is heavily dependent on their consumption or export. Due to overconsumption, they are rapidly being depleted.
QIT-Fer et Titane is a Canadian mining company located in Quebec. The company operates an ilmenite mine at Lac Allard in northern Quebec, and in the southern Quebec municipality of Sorel-Tracy operates refining facilities that produce titanium dioxide, pig iron, steel, and other metal products.
Africa has a large quantity of natural resources, including diamonds, sugar, salt, gold, iron, cobalt, uranium, copper, bauxite, silver, petroleum, natural gas and cocoa beans, but also tropical timber and tropical fruit.
Mining is important to the national economy of Mongolia. Mongolia is one of the 29 resource-rich developing countries identified by the International Monetary Fund and exploration of copper and coal deposits are generating substantial additional revenue.
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.
The mining industry of Madagascar is mostly on a small scale, centred mainly around remote locations with large mineral deposits. Mining potential is noted in industrial and metallic minerals, energy, precious and semi-precious stones, as well as ornamental stone. The mining sector was neglected by the government for decades prior to the mid-2000s. In 2013, the mining industry, a main source of foreign investment, was struggling due to "low metals prices and distrustful companies", attributed to a 2009 coup.
North Limited was a diversified mining and resources company. Although based in Australia, its operations eventually extended to six continents. By the late 20th century the company had become the fourth largest iron ore exporter in the world with expansion underway which would have made it equal third. Its biggest asset was a majority stake in Robe River, a major miner of the Pilbara iron ore deposits of Western Australia and the world's lowest cost producer of iron ore.
