List Of Countries By Uranium Reserves
Uranium reserves are reserves of recoverable uranium, regardless of isotope, based on a set market price. The list given here is based on ''Uranium 2020: Resources, Production and Demand'', a joint report by the OECD Nuclear Energy Agency and the International Atomic Energy Agency. Figures are given in metric tonnes. The reserves figures denote identified resources as of 1 January 2015, consisting of reasonably assured resources (RAR) plus inferred resources recoverable at a cost range of below US$260/kg U. The list also includes cumulative historical production figures. The amount of ultimately recoverable uranium depends strongly on what one would be willing to pay for it. Uranium is a widely distributed metal with large low-grade deposits that are not currently considered profitable. As of 2015, 646,900 tonnes of reserves are recoverable at US$40 per kilogram of uranium, while 7,641,600 tonnes of reserves are recoverable at $260 per kilogram. Moreover, much of Canada, Greenl ...

Uranium Reserves
Uranium is a chemical element; it has symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactively decays, usually by emitting an alpha particle. The half-life of this decay varies between 159,200 and 4.5 billion years for different isotopes, making them useful for dating the age of the Earth. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. Many contemporary u ...

Estonian Soviet Socialist Republic
The Estonian Soviet Socialist Republic, (abbreviated Estonian SSR, Soviet Estonia, or simply Estonia ) was an administrative subunit (Republics of the Soviet Union, union republic) of the former Soviet Union (USSR), covering the Occupation of the Baltic states, occupied and annexed territory of Estonia in 1940–1941 and 1944–1991. The Estonian SSR was nominally established to replace the until then independent Republic of Estonia on 21 July 1940, a month after the 16–17 June 1940 Timeline of the occupation of the Baltic states, Soviet military invasion and occupation of the country during World War II. After the installation of a Stalinism, Stalinist communist government, government which, backed by the occupying Soviet Red Army, declared Estonia a Soviet constituency, the Estonian SSR was subsequently incorporated into the Soviet Union as a union republic on 6 August 1940. Estonia was Occupation of Estonia by Nazi Germany, occupied by Nazi Germany in 1941, and administer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium Mining By Country
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. Africa Democratic Republic of the Congo (DRC) Uranium mining in the DRC ceased in 2004 with the closure of the Shinkolobwe mine. Uranium for the Manhattan Project nuclear bombs that were used in the bombing of Hiroshima and Nagasaki at the end of the Second World War came from Shinkolobwe, in the mineral rich province of Katanga, at that time in the Belgian Congo. In 2009 the French conglomerate Areva executed an agreement with the Congolese Minister of Mines on uranium prospecting and mining. Work would start with a detailed inventory of mining sites and an update of all databases. In 2011 Areva disclosed that it was unlikely to develop a uranium mine in the DRC until the country became more politically stable. Gabon ...

Uranium Mining
Uranium mining is the process of extraction of uranium ore from the earth. Over 50,000 tons of uranium were produced in 2019. 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 tons per year included Namibia, Niger, Russia, Uzbekistan and China. Nearly all of the world's mined uranium is used to power nuclear power plants. Historically uranium was also used in applications such as uranium glass or ferrouranium but those applications have declined due to the radioactivity and toxicity of uranium and are nowadays mostly supplied with a plentiful cheap supply of depleted uranium which is also used in Armour-piercing ammunition, uranium ammunition. In addition to being cheaper, depleted uranium is also less radioactive due to a lower content of short-lived and than natural uranium. Uranium is mined by in-situ leaching (57% of world production) or by convent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uzbek Soviet Socialist Republic
The Uzbek Soviet Socialist Republic (, ), also known as Soviet Uzbekistan, the Uzbek SSR, UzSSR, or simply Uzbekistan and rarely Uzbekia, was a Republics of the Soviet Union, union republic of the Soviet Union.

The Tajik Republic was created on 5 December 1929 as a national entity for the Tajik people within the Soviet Union. It succeeded the Tajik Autonomous Soviet Socialist Republic (Tajik SSR), which had been created on 14 October 1924 as a part of the predominantly Turkic Uzbek SSR in the process of national delimitation in Soviet Central Asia.

Permafrost
Permafrost () is soil or underwater sediment which continuously remains below for two years or more; the oldest permafrost has been continuously frozen for around 700,000 years. Whilst the shallowest permafrost has a vertical extent of below a meter (3 ft), the deepest is greater than . Similarly, the area of individual permafrost zones may be limited to narrow mountain summits or extend across vast Arctic regions. The ground beneath glaciers and ice sheets is not usually defined as permafrost, so on land, permafrost is generally located beneath a so-called active layer of soil which freezes and thaws depending on the season. Around 15% of the Northern Hemisphere or 11% of the global surface is underlain by permafrost, covering a total area of around . This includes large areas of Alaska, Canada, Greenland, and Siberia. It is also located in high mountain regions, with the Tibetan Plateau being a prominent example. Only a minority of permafrost exists in the Southern Hemi ...
