Elliot Lake
Elliot Lake is a city in Algoma District, Ontario, Canada. It is north of Lake Huron, midway between the cities of Sudbury and Sault Ste. Marie in the Northern Ontario region. Once dubbed the "uranium capital of the world," Elliot Lake has since diversified to a hub for forest harvesting, mine reclamation expertise, and advanced manufacturing. Elliot Lake is now known as a place for affordable retirement living, waterfront cottage lots and as a four-season destination. History Prior to the settlement of the city, a seasonal Ojibwa village extended along the lake's shoreline near the present hospital. The town takes its name from the lake. There is no official record of origin of name; the earliest appearance is on the Dominion map of 1901. Folklore suggest it was named for a logging camp cook who drowned in the lake. The townsite name was approved on August 14, 1952. Elliot Lake was incorporated as a city in 1990. Uranium mining The city was established as a planned community ...

Uranium Mines In Ontario
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 (99.2739–99.2 ... [...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 conventional und ... [...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 Agen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacnor Mine
The Lacnor Mine, is an abandoned uranium mine in the Elliot Lake area of Ontario, owned by Rio Algom Ltd. The site has been rehabilitated and its tailings facility is currently undergoing environmental monitoring by Denison Environmental Services. The site was in operation from 1957 to 1960, during which time it produced 3.4 million tonnes of ore. History Elliot Lake Mining District The region of Elliot Lake, Ontario was a mecca of Canadian mineral mining from the 1950s to the early 1990s. The region housed ten mines and five mills (Lacnor Mine, Nordic Mine, Panel Mine/Mill, Pronto Mine/Mill, Quirke Mine/Mill, Stanleigh Mine/Mill and the Spanish American Mine/Mill), all operated by the Rio Algom Company. All of the mines and mills in Elliot Lake either ran out their contracts or were shut down by the early 1990s due to the discovery of high-grade uranium deposits in Australia and Saskatchewan. This meant there was no longer a need for the low-grade ore from Elliot Lake, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buckles Mine
The Buckles Mine is an historical uranium mine located approximately 4.5 km southeast of Elliot Lake, Ontario, owned and operated by Rio Algom Ltd. The site has been rehabilitated. Environmental monitoring is ongoing as part of the monitoring for the nearby Nordic Mine. History The mine was owned by Buckles Algoma Uranium Mines Limited, and was bought in 1955 by Spanish American Mines Limited in 1955. 1955 reserves were indicated to be 486,500 tons at 0.124% U308 in a 10 feet thick zone located 75 feet underground. About 500 tons of ore was shipped to the Spanish American mine for processing daily. The mine was in operation from 1957 to 1958, during which time it produced 276,000 tonnes of ore.

Milliken Mine
The Milliken Mine is an abandoned uranium mine located approximately 2.5 km northeast of Elliot Lake, Ontario, owned and operated by Rio Algom Ltd. The site has been rehabilitated and its tailings facility is currently undergoing environmental monitoring by Denison Environmental Services as part of the monitoring of the Stanleigh Mine and tailings facility. The site was in operation from 1958 to 1964, during which time it produced 6.3 million tonnes of ore A company townsite existed on the west side of the Milliken Mine road, 1/2 km from the mine. It provided accommodations for staff employees. In the early 1970s, the townsite became abandoned as all the houses were relocated to empty lots in Elliot Lake or transported to other communities along the North Shore of highway 17. Although the mine closed in the mid 1960s' many of the buildings including the mill, 2 head-frames and some offices remained in place well into the 1990s. Several of the offices were used by the Equ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium Trioxide
Uranium trioxide (UO3), also called uranyl oxide, uranium(VI) oxide, and uranic oxide, is the hexavalent oxide of uranium. The solid may be obtained by heating uranyl nitrate to 400 °C. Its most commonly encountered polymorph, γ-UO3, is a yellow-orange powder. Production and use There are three methods to generate uranium trioxide. As noted below, two are used industrially in the reprocessing of nuclear fuel and uranium enrichment. # U3O8 can be oxidized at 500 °C with oxygen. Note that above 750 °C even in 5 atm O2 UO3 decomposes into U3O8. # Uranyl nitrate, UO2(NO3)2·6H2O can be heated to yield UO3. This occurs during the reprocessing of nuclear fuel. Fuel rods are dissolved in HNO3 to separate uranyl nitrate from plutonium and the fission products (the PUREX method). The pure uranyl nitrate is converted to solid UO3 by heating at 400 °C. After reduction with hydrogen (with other inert gas present) to uranium dioxide, the uranium can be used in n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
