Cameco
Cameco Corporation (formerly Canadian Mining and Energy Corporation) is the world's largest publicly traded uranium company, based in Saskatoon, Saskatchewan, Canada. In 2015, it was the world's second largest uranium producer, accounting for 18% of world production. History The Canadian Mining and Energy Corporation was formed in 1988 by the merger and privatization of two Crown corporations: the federally owned Eldorado Nuclear Limited (known previously as Eldorado Mining and Refining Limited) and Saskatchewan-based Saskatchewan Mining Development Corporation (SMDC). The name was later shortened to "Cameco Corporation". The new company was initially owned 62% by the provincial government and 38% by the federal government. The initial public offering (IPO) for 20% of the company was conducted in July, 1991. Government ownership of the company decreased over the next eleven years, with full privatization occurring in February, 2002. In 1996, Cameco acquired Power Resource ...

Uranium
Uranium is a chemical element with the 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 is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. 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. In nature, uranium is found as uranium-238 (99.2739 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium Mining
Uranium mining is the process of extraction of uranium ore from the ground. Over 50 thousand 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, the United States, 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 of uranium and are nowadays mostly supplied with a plentiful cheap supply of depleted uranium which is also used in 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 conventio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wyoming
Wyoming () is a state in the Mountain West subregion of the Western United States. It is bordered by Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With a population of 576,851 in the 2020 United States census, Wyoming is the least populous state despite being the 10th largest by area, with the second-lowest population density after Alaska. The state capital and most populous city is Cheyenne, which had an estimated population of 63,957 in 2018. Wyoming's western half is covered mostly by the ranges and rangelands of the Rocky Mountains, while the eastern half of the state is high-elevation prairie called the High Plains. It is drier and windier than the rest of the country, being split between semi-arid and continental climates with greater temperature extremes. Almost half of the land in Wyoming is owned by the federal government, generally protected for public uses. The stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uranium Ore Deposits
Uranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust. Uranium is one of the more common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans. The challenge for commercial uranium extraction is to find those areas where the concentrations are adequate to form an economically viable deposit. The primary use for uranium obtained from mining is in fuel for nuclear reactors. Globally, the distribution of uranium ore deposits is widespread on all continents, with the largest deposits found in Australia, Kazakhstan, and Canada. To date, high-grade deposits are only found in the Athabasca Basin region of Canada. Uranium deposits are generally classified based on host rocks, structural setting, and mineralogy of the deposit. The most widely used classification scheme was developed by the International Atomic Energy Age ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In-situ Leach
In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, ''in situ''. In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining. The process initially involves the drilling of holes into the ore deposit. Explosive or pathways in the deposit for solution to penetrate. Leaching solution is pumped into the deposit where it makes contact with the ore. The solution bearing the dissolved ore content is then pumped to the surface and processed. This process allows the extraction of metals and salts from an ore body without the need for conventional mining involving drill-and-blast, open-cut or underground mining. Process In-situ leach mining involves pumping of a lixiviant into the ore body via a borehole, which circulates through the porou ...

Rio Algom
Rio Algom was a mining corporation that was purchased by BHP#Billiton, Billiton in 2000 and is now part of BHP. Uranium It operated many uranium mining, uranium mines and mills in the Elliot Lake region of Ontario, Canada, including the Lacnor Mine, Nordic Mine, Panel Mine, Pronto Mine, Quirke Mine, Milliken Mine, Stanleigh Mine, and the Spanish-American Mine. These operated from the 1950s to the 1990s. It got ownership of a uranium mill in the Ambrosia Lake region of New Mexico when it purchased the Quivira Mining Corporation from Kerr-McGee in 1989. The mill had only been active from 1958-1985. However from 1989-2002 it produced uranium from recovered mine-water. The 2017 performance of Rio Algom, who own nine decommissioned uranium mines at Elliot Lake, was described as "below expectations" by the Canadian Nuclear Safety Commission. The commission reported radium releases above limits at the Stanleigh effluent treatment plant, prompting engineering work plus increased site m ...

Buildings And Structures In Converse County, Wyoming
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artisti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
