Rabbit Lake Mine
Rabbit Lake is the second largest uranium milling facility in the western world, and is the longest operating uranium production facility in Saskatchewan. The facility is located approximately 800 km north of Saskatoon, Saskatchewan, on the northeast edge of the uranium rich Athabasca Basin. The closest community is Wollaston Lake, about 40 kilometers by lake or air. Rabbit Lake was the first Canadian mine to offer a seven-days-in/seven-days-out commuter system of staffing. Access is provided by Highway 905. Production at Rabbit Lake was suspended in April 2016. Operations The Rabbit Lake deposit was discovered in 1968 and production started in 1975 using open-pit mining methods. The Rabbit Lake pit was mined out in 1984. Exploration resulted in the discovery of additional deposits in the area. The Eagle Point deposit is being mined using underground mining methods. Between 1975 and 2011, Rabbit Lake has produced 186.3 million pounds U3O8. Recent exploration drilling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Athabasca Basin
The Athabasca Basin is a region in the Canadian Shield of northern Saskatchewan and Alberta, Canada. It is best known as the world's leading source of high-grade uranium and currently supplies about 20% of the world's uranium. The basin is located just to the south of Lake Athabasca, west of Wollaston Lake, and encloses almost all of Cree Lake. It covers about in Saskatchewan and a small portion of Alberta. The surface of the basin consists of main sandstone sediment varying from in depth. The uranium ore is mostly found at the base of this sandstone, at the point where it meets the basement. On the northern and eastern edges are the communities of Fort Chipewyan in Alberta and Camsell Portage, Stony Rapids, Fond du Lac, Black Lake and Wollaston Lake in Saskatchewan. Much of the Athabasca Basin is within the migratory range of the Beverly caribou herd a major source of sustenance for the Denesuline communities. Within the basin are the Athabasca Sand Dunes Provincia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Institute Of Mining, Metallurgy And Petroleum
The Canadian Institute of Mining, Metallurgy and Petroleum (CIM) is a not-for-profit technical society of professionals in the Canadian minerals, metals, materials and energy industries. CIM's members are convened from industry, academia and government. History In March 1898, the Canadian Mining Institute was founded in Montreal at the second annual meeting of the Federated Canadian Mining Institute, which was dissolved. The Institute was incorporated by an Act of Parliament to include all former provincial groups except The Mining Society of Nova Scotia, which remained a separate body. In 1902, The Institute formed its first Branches in Sherbrooke, Quebec, Kingston, Ontario, and Nelson, British Columbia. In 1918, the Mining Society of Nova Scotia formally became affiliated with the Canadian Mining Institute In 1920, Metallurgy Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-me ...

Uranium Mines In Canada
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] |
McClean Lake Mine
The McClean Lake mine is a uranium mine and milling operation located west of Wollaston Lake, about 700 kilometres north of Saskatoon, in the Athabasca Basin region of Saskatchewan, Canada. The McClean ore body was discovered in 1979, followed by the discovery of the JEB ore body in 1982. From 1985 to 1990, a cluster of deposits named Sue A, Sue B and Sue C were discovered. Production from the JEB and Sue C open pits commenced in 1999. Upon depletion, the JEB pit was converted to a Tailings Management Facility (TMF). The Sue C pit will be converted to a TMF for the disposal of waste from the McLean Lake and Cigar Lake operations. Production from the Sue A mine and development of the Sue E mine, commenced in mid-2005. After the tailings from the milling operations and waste rock from the mining operations are chemically treated to precipitate arsenic and nickel they are pumped into the TMF. There they form a consolidated mass of much lower permeability than the surrounding sandstone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Key Lake Mine
The Key Lake mine is a former uranium mine in Saskatchewan, Canada. It is north of Saskatoon by air on the southern rim of the uranium-rich Athabasca Basin. Key Lake was initially developed to open-pit mine two nearby uranium ore deposits: the Gaertner deposit and the Deilmann deposit. Mining of this ore ceased in the late 1990s; the Key Lake mill now processes uranium ore from the McArthur River mine and from existing stockpiles on site. High-grade ore from McArthur river is blended with lower grade local rock before being passed through the mill. The mill has a permitted annual production capacity of 25 million pounds of U3O8. In addition, ammonium sulfate fertilizer is produced as a byproduct from used reagents. The pits of the mined out local deposits are being used as mill tailings management facilities. Its deposits jointly remain one of the higher grade large uranium deposits discovered, with an average grade of over 2% U3O8. Key Lake was the third largest uranium depos ...

Cluff Lake Mine
Cluff Lake mine is decommissioned former uranium mine located in northern Saskatchewan, located 30 km east of the provincial border with Alberta and approximately 75 kilometres south of Lake Athabasca. The mine and mill were owned and operated by AREVA Resources Canada, formerly COGEMA Resources and is now owned and operated by Orano Canada. History The mine operated from 1981 and used both open pit and underground extraction. Mining infrastructure consisted of a central mill, above ground tailings management area, 3 open pits, 2 underground mines, associated waste rock piles, and site infrastructure including the Cluff Lake airstrip and residences. The mine expected to close in 2000, but additional higher ore grades in the underground mine allowed production to continue for an additional two years. The mine closed in 2002 once the ore reserved were depleted. Total production during the mine's 22-year operating life was over 62 million pounds of yellowcake. Decommissionin ...

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] |
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] |

Cigar Lake Mine
The Cigar Lake Mine is a large high-grade underground uranium mine, located in the uranium-rich Athabasca Basin of northern Saskatchewan, Canada, at the south-west corner of Waterbury Lake. The deposit, discovered in 1981, is second in size of high-grade deposits only to the nearby McArthur River mine. Other deposits, such as Olympic Dam in Australia, contain more uranium but at lower grades. History Full-scale construction began in 2005 with production originally planned for 2007, but the mine experienced a catastrophic water inflow in October 2006, which flooded the mine. A second inflow occurred in 2008 during the first attempt at dewatering the mine after sealing the initial inflow. Remediation efforts continued, and re-entry was successfully accomplished in 2010. Production was delayed several times with the startup dates being announced for 2011, 2013, and 2014. On March 13, 2014, ore production began at the mine, with the mining system and underground processing circuit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Provinces And Territories Of Canada
Within the geographical areas of Canada, the ten provinces and three territories are sub-national administrative divisions under the jurisdiction of the Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)—united to form a federation, becoming a fully independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the world's second-largest country by area. The major difference between a Canadian province and a territory is that provinces receive their power and authority from the ''Constitution Act, 1867'' (formerly called the ''British North America Act, 1867''), whereas territorial governments are creatures of statute with powers delegated to them by the Parliament of Canada.
