Cigar Lake
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] |
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] |
Uranium Ore
Uranium ore deposits are economically recoverable concentrations of 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 weak ... within the Earth's crust (geology), 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 deposi ...

Death Of Kenton Joel Carnegie
Kenton Joel Carnegie (11 February 1983 – 8 November 2005) was a 22-year-old Canadian geological engineering student from Ontario on a work term from the University of Waterloo who died in a wild animal attack while he was walking near Points North Landing in Saskatchewan, Canada. Waste dumping attracted black bears and timber wolves to the region. According to a trucker who said he met Carnegie in the cafeteria a few days before his death, he had passed around close-range photographs of large wolf pups that had approached him during walks in nearby woods, and been warned by the trucker that such encounters were extremely dangerous. A bush pilot said he warned Carnegie about an incident in which adult wolves had menaced others walking outside the camp, but Carnegie's family said he would not have taken risks if warned. After reviewing evidence, which included wolf tracks left around the body, the finding of a coroner's inquest was that Carnegie had been killed by wolves. If tr ...

Triuranium Octoxide
Triuranium octoxide (U3O8) is a compound of uranium. It is present as an olive green to black, odorless solid. It is one of the more popular forms of yellowcake and is shipped between mills and refineries in this form. U3O8 has potential long-term stability in a geologic environment. In the presence of oxygen (O2), uranium dioxide (UO2) is oxidized to U3O8, whereas uranium trioxide (UO3) loses oxygen at temperatures above 500 °C and is reduced to U3O8. The compound can be produced by any one of three primary chemical conversion processes, involving either uranium tetrafluoride (UF4) or uranyl fluoride (UO2F2) as intermediates. It is generally considered to be the more attractive form for disposal purposes because, under normal environmental conditions, U3O8 is one of the most kinetically and thermodynamically stable forms of uranium. Its particle density is 8.3 g cm−3. Triuranium octoxide is converted to uranium hexafluoride for the purpose of uranium enrichment. Solid ...

Deep Geological Repository
A deep geological repository is a way of storing hazardous or radioactive waste within a stable geologic environment (typically 200–1000 m deep). It entails a combination of waste form, waste package, engineered seals and geology that is suited to provide a high level of long-term isolation and containment without future maintenance. This will prevent any radioactive dangers. A number of mercury, cyanide and arsenic waste repositories are operating worldwide including Canada (Giant Mine) and Germany (potash mines in Herfa-Neurode and Zielitz) and a number of radioactive waste storages are under construction with the Onkalo in Finland being the most advanced. Principles and background Highly toxic waste that cannot be further recycled must be stored in isolation to avoid contamination of air, ground and underground water. Deep geological repository is a type of long-term storage that isolates waste in geological structures that are expected to be stable for millions of years, ...

Formation (geology)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...
