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] |
List Of Uranium Mines
Uranium production is carried out in about 13 countries around the world, in 2017 producing a cumulative total of 59,462 tonnes of uranium (tU). The international producers were Kazakhstan (39%), Canada (22%), Australia (10%), Namibia (7.1%), Niger (5.8%), Russian Federation (4.9%), Uzbekistan (4.0%), China (3.2%), United States (1.6%), Ukraine (0.9%), India (0.7%), South Africa (0.5%) and Pakistan (0.1%). Since 2009 the in-situ leach (ISL) operations of Kazakhstan have been producing the largest share of world uranium. The largest conventional uranium mines are Cigar Lake and McArthur River (Canada); Ranger and Olympic Dam (Australia); Krasnokamensk (Russia) and Rossing (Namibia). The largest uranium producers are Cameco, Rio Tinto, Areva, KazAtomProm and ARMZ-TVEL. The production methods employed are conventional underground and open cast (50%) and in-situ leaching (50%). About 50 uranium production centers are operational. Viable projects Potentially viable projects N ... [...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] |
Uranium Mining In The Bancroft Area
Uranium mining around Bancroft, Ontario, was conducted at four sites, beginning in the early 1950s and concluding by 1982. Bancroft was one of two major uranium-producing areas in Ontario, and one of seven in Canada, all located along the edge of the Canadian Shield. In the context of mining, the "Bancroft area" includes Haliburton, Hastings, and Renfrew counties, and all areas between Minden and Lake Clear. Activity in the mid-1950s was described by engineer A. S. Bayne in a 1977 report as the "greatest uranium prospecting rush in the world". As a result of activities at its four major uranium mines, Bancroft experienced rapid population and economic growth throughout the 1950s. By 1958, Canada had become one of the world's leading producers of uranium; the $274 million of uranium exports that year represented Canada's most significant mineral export. By 1963, the federal government had purchased more than $1.5 billion of uranium from Canadian producers, but soon thereaft ...

Greyhawk Mine
Greyhawk Mine is a decommissioned underground uranium mine located in Faraday Township near Bancroft, Ontario. It operated from 1954 to 1959 and from 1976 to 1982. The mine produced 80,247 tons of uranium ore, of which 0.069% was U3O8 worth $834,899. Aside from uranium, the mine has produced some of the world's best samples of Kainosite-(Y). Uranium discovery - 1922 to 1954 Uranium was first discovered in the nearby area of Cardiff in 1922 by W. M. Richardson. Between 1953 and 1956, one hundred area prospects were opened, including one by one which developed into Greyhawk Mine. Mine operations - 1954 to 1982 In 1954, Goldhawk Porcupine Mines Limited (who later became Goldhawk Uranium Mines Limited) undertook geology surveys, drilling to 450 feet deep. During 1955 and 1956 Greyhawk Uranium Mines Limited sunk a vertical shaft to 361 feet creating three levels at depths of 110 feet, 211 feet, and 333 feet. They then drilled 114 holes (totalling 42,299 feet of drilling). By ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dyno Mine
Dyno Mine is a decommissioned underground uranium mine located at Cardiff, near Farrel Lake, approximately 30km southwest of Bancroft, Ontario. It operated from 1958 to 1960. Uranium discovery - 1922 to 1956 Uranium was first discovered in the area of Cardiff (now known as Highlands East) in 1922 by W. M. Richardson.
