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.
Gold cyanidation is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after froth flotation.
Mining in Japan is minimal because Japan does not possess many on-shore mineral resources. Many of the on-shore minerals have already been mined to the point that it has become less expensive to import minerals. There are small deposits of coal, oil, iron and minerals in the Japanese archipelago. Japan is scarce in critical natural resources and has been heavily dependent on imported energy and raw materials. There are major deep sea mineral resources in the seabed of Japan. This is not mined yet due to technological obstacles for deep sea mining.

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.
Vasile Frank Timiș is a Romanian-Australian businessman living in London, with interests in mining and oil extraction industries. The Sunday Times Rich List estimated his wealth at £162m (US$238m) as of April 2008, making him the 497th richest person in Britain. The Romanian magazine Capital reckoned Timiș to be the 9th richest Romanian, estimating his wealth at $290m as of 2006. In 2012 he became the richest Romanian with a net worth of £1.34 billion (US$2.13 billion). A BBC News investigation alleged that Timiș paid £35.20 in tax in 2017 despite living a life of luxury, and included a statement from the Tax Justice Network suggesting that Timiș be investigated for tax fraud. In 2017, BP acquired Frank Timis's stake in a Senegal gas field for $250 million, with documents later revealing an additional $9–12 billion in royalties to be paid to Timis's company. Both parties deny wrongdoing, with Timis having an estimated net worth of $12 billion.
Stéphanie Danielle Roth is a French-Swiss environmental campaigner working on environmental, heritage and social issues with a focus on mining and farming.
Hydrocarbons are the leading sector in Algeria's mineral industry, which includes diverse but modest production of metals and industrial minerals. In 2006, helium production in Algeria accounted for about 13% of total world output. Hydrocarbons produced in Algeria accounted for about 2.9% of total world natural gas output and about 2.2% of total world crude oil output in 2006. Algeria held about 21% of total world identified resources of helium, 2.5% of total world natural gas reserves, and about 1% of total world crude oil reserves.
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 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 in New Zealand began when the Māori quarried rock such as argillite in times prior to European colonisation. Mining by Europeans began in the latter half of the 19th century.
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.
Mineral industry of Colombia refers to the extraction of valuable minerals or other geological materials in Colombia. Colombia is well-endowed with minerals and energy resources. It has the largest coal reserves in Latin America, and is second to Brazil in hydroelectric potential. Estimates of petroleum reserves in 1995 were 3.1 billion barrels (490,000,000 m3). Colombia also possesses significant amounts of nickel and gold. Other important metals included platinum and silver, which were extracted in much smaller quantities. Colombia also produces copper, small amounts of iron ore, and bauxite. Nonmetallic mined minerals include salt, limestone, sulfur, gypsum, dolomite, barite, feldspar, clay, magnetite, mica, talcum, and marble. Colombia also produces most of the world's emeralds. Despite the variety of minerals available for exploitation, Colombia still had to import substances such as iron, copper, and aluminum to meet its industrial needs.
The 2000 Baia Mare Cyanide spill was a leak of cyanide near Baia Mare, Romania, into the Someș River by the gold mining company Aurul, a joint-venture of the Australian company Esmeralda Exploration and the Romanian government.
Rovina mine is a proposed open pit mine in the west of Romania in Hunedoara County, 18 km north of Deva and 388 km north of the capital, Bucharest. Rovina is a large gold and copper deposit with estimated reserves of 4 million oz of gold and 244,000 tonnes of copper, and the largest proposed copper-gold project in the EU. The project is wholly owned by the Toronto-based company Eurosun Mining,.
Roșia Montană Project was a proposed gold and silver mine in Roșia Montană, Romania. If approved, it would have become Europe's largest open-pit gold mine and it would have used the gold cyanidation mining technique. The project met with widespread protests in 2013 that indefinitely delayed the project, which saw its end in 2021, when Roșia Montană became a part of the UNESCO World Heritage list and was also included in the List of World Heritage in Danger. Following these measures, any mining activity in Roșia Montană is prohibited in the future.
This is a list of notable events relating to the environment in 2000. They relate to environmental law, conservation, environmentalism and environmental issues.
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.
Gold cyanidation is a chemical process for extracting gold from low-grade ore. Used in Romania for decades, the process came into debate following the 2000 Baia Mare cyanide spill and proposal of the Roșia Montană Project, which would create the largest operation for gold extraction using cyanides in Europe.
