Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. Exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material.
The Ranger Uranium Mine was a uranium mine in the Northern Territory of Australia. The site is surrounded by, but separate from Kakadu National Park, 230 km east of Darwin. The orebody was discovered in late 1969, and the mine commenced operation in 1980, reaching full production of uranium oxide in 1981 and ceased production on 8 January 2021. It was operated by Energy Resources of Australia, a 68% subsidiary of Rio Tinto Group. Uranium mined at Ranger was sold for use in nuclear power stations in Asia, Europe and North America.
Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tonnes per year included Namibia, Niger, Russia, Uzbekistan, the United States, and China. Nearly all of the world's mined uranium is used to power nuclear power plants.
Koolan Island is an island off the Kimberley coast of Western Australia in the Buccaneer Archipelago. It is about 1,900 km north of Perth, and about 130 km (81 mi) north of Derby. It hosts deposits of high-grade iron ore.
Uranium mining in the United States produced 173,875 pounds (78.9 tonnes) of U3O8 in 2019, 88% lower than the 2018 production of 1,447,945 pounds (656.8 tonnes) of U3O8 and the lowest US annual production since 1948. The 2019 production represents 0.3% of the anticipated uranium fuel requirements of the US's nuclear power reactors for the year.
Uranium mining in Colorado, United States, goes back to 1872, when pitchblende ore was taken from gold mines near Central City, Colorado. The Colorado uranium industry has seen booms and busts, but continues to this day. Not counting byproduct uranium from phosphate, Colorado is considered to have the third largest uranium reserves of any US state, behind Wyoming and New Mexico.
Uranium mining in Wyoming was formerly a much larger industry than it is today. Wyoming once had many operating uranium mines, and still has the largest known uranium ore reserves of any state in the U.S. At the end of 2008, the state had estimated reserves dependent on price: 539 million pounds of uranium oxide at $50 per pound, and 1,227 million pounds at $100 per pound.
Uranium mining in Arizona has taken place since 1918. Prior to the uranium boom of the late 1940s, uranium in Arizona was a byproduct of vanadium mining of the mineral carnotite.
Hpakant is a town in Hpakant Township, Kachin State of the northernmost part of Myanmar (Burma). It is located on the Uyu River 350 km north of Mandalay in the middle of one of the world's most inhospitable and malaria infested jungles, cut off for several months a year during the monsoons. It is famous for its jade mines which produce the world's best quality jadeite.
The Midnite Mine is an inactive former uranium mine in the Selkirk Mountains of the American state of Washington that operated from 1955 to 1965 and again from 1968 to 1981. Located within the reservation of the Spokane Tribe of Indians, it is approximately 8 miles (13 km) from Wellpinit, Stevens County. The mine was listed as a Superfund site under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) on May 11, 2000. In addition to elevated levels of radioactivity, heavy metals mobilized in acid mine drainage pose a potential threat to human health and the environment.
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.
SAG/SDAG Wismut was a uranium mining company in East Germany during the time of the cold war. It produced a total of 230,400 tonnes of uranium between 1947 and 1990 and made East Germany the fourth largest producer of uranium ore in the world at the time. It was the largest single producer of uranium ore in the entire sphere of control of the USSR. In 1991 after German reunification it was transformed into the Wismut GmbH company, owned by the Federal Republic of Germany, which is now responsible for the restoration and environmental cleanup of the former mining and milling areas. The head office of SDAG Wismut / Wismut GmbH is in Chemnitz-Siegmar.
Uranium mining in Namibia is of considerable importance to the national economy. In 2020, Namibia produced 11% of uranium worldwide, ranked as the 4th largest producer, behind Kazakhstan, Canada, and Australia.
The world's largest producer of uranium is Kazakhstan, which in 2019 produced 43% of the world's mining output. Canada was the next largest producer with a 13% share, followed by Australia with 12%. Uranium has been mined in every continent except Antarctica.
The Husab Mine, also known as the Husab Uranium Project, is a uranium mine near the town of Swakopmund in the Erongo region of western-central Namibia. The mine is located approximately 60 kilometres (37 mi) from Walvis Bay. The Husab Mine is expected to be the second largest uranium mine in the world after the McArthur River uranium mine in northern Saskatchewan, Canada and the largest open-pit mine on the African continent. Mine construction started in 2014. The Husab Mine started production towards the end of 2016 after completion of the sulfuric acid leaching plant.
The Pa'O Youth Organization or PYO is a youth organization in Burma. It was founded by Pa'O women, monks and young people in Shan State, northern Burma, on 4 December 1998. It describes itself as independent, democratic and non-violent, and is a member of the Nationalities Youth Forum and the Student Youth Congress of Burma.
The Pinpet Mining Project is an open-pit iron ore mine in Mount Pinpet, Shan State, Myanmar. Plans for the project started in 2003, and construction of an iron ore factory has been underway since 2004. The Pinpet deposit consists of an estimated 10 million tons of hematite with 56.4% iron and reserves of limonite at 70 million tons with 42.6% iron. The mountain also has an estimated deposit of 30 million tons of limestone, which can be used to make cement. A cement factory under the Burmese Kanbawza Development Co. is currently under construction.
The mining industry of Liberia has witnessed a revival after the civil war which ended in 2003. Gold, diamonds, and iron ore form the core minerals of the mining sector with a new Mineral Development Policy and Mining Code being put in place to attract foreign investments. In 2013, the mineral sector accounted for 11% of GDP in the country and the World Bank has projected a further increase in the sector by 2017.
The mining industry of Sudan was mostly driven by extraction fuel minerals, with petroleum accounting for a substantial contribution to the country's economy, until the autonomous region of Southern Sudan became an independent country in July 2011. Gold, iron ore, and base metals are mined in the Hassai Gold Mine. Chromite is another important mineral extracted from the Ingessana Hills. Other minerals extracted are gypsum, salt, and cement. Phosphate is found in Mount Kuoun and Mount Lauro in eastern Nuba. Reserves of zinc, lead, aluminium, cobalt, nickel in the form of block sulfides, and uranium are also established. Large reserves of iron ore have been established.
