Uranium Mining In Canada
For many years, North America was the largest exporter of uranium ore in the world and has been a major world producer since demand for uranium developed. In 2009 Kazakhstan took over top spot, relegating Canada to second. 20% of the world's primary uranium production came from mines in Canada in 2009. 14.5% of the world production came from one mine, McArthur River. Currently the only producing area in Canada is northern Saskatchewan, although other areas have had active mines in the past. History Discovery of uranium Canada's first recorded discovery of uranium came in the 1930s 3 when prospector Gilbert LaBine discovered pitchblende, a major uranium bearing mineral, on the shores of the Great Bear Lake in the Northwest Territories. This discovery led Labine's company, Eldorado Gold Mines Limited, to develop the Eldorado Mine at Port Radium, Northwest Territories in 1932 and a refinery to extract Radium from the ore in Port Hope, Ontario, the following year.

A Miner Hauling A Car Of Silver Radium Ore, 340 Feet Below The Surface, Eldorado Mine Of Great Bear Lake
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it f ...

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 ...

Bancroft, Ontario
Bancroft () is a town located on the York River in Hastings County in the Canadian province of Ontario. It was first settled in the 1850s by United Empire Loyalists and Irish immigrants. From the mid-1950s to about 1982, mining was the primary industry. A village until 1999, Bancroft then merged with Dungannon Township to form the Town of Bancroft. The population at the time of the 2016 Census was 3,881; the regional population is 40,000. There are 150,000 visitors to Bancroft, annually. History By 1823, the government had purchased nearly two million acres of land from the Chippewa and Mississaga First Nations including a tract on the York River in Hastings County which had been established in 1792. The area was mapped in 1835 by explorer David Thompson. The first family to build a cabin here, the Clarks in 1853, did so to take advantage of the fur trade. Early settlers included James Cleak and Alfred Barker from England who arrived in 1855, settling on Quarry Lake. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rayrock Mine
The Rayrock Mine was a uranium producing venture in the Northwest Territories, Canada. It is located on the south side of Maryleer Lake and the north shore of Fault Lake, 169 kilometers northwest of Yellowknife and 74 kilometres northwest of Rae. Radioactive deposits were originally staked in 1948 and then restaked in 1950. American Yellowknife Mines Limited explored the site with detailed Geiger surveys and extensive trenching in the early 1950s. In 1954 exploration work included over of surface diamond drilling, and the company was reorganized as Rayrock Mines Limited. Underground development began in 1955 with the driving of a long adit tunnel to intersect the radioactive zones below surface. The mine opened in June 1957 with a 150 tons per day leaching mill. Development was expanded and the mine reached depths of by the end of 1957. The failure to locate ore in significant quantity below the level resulted in the cessation of mining on July 31, 1959.

Mineral Exploration
Mining in the engineering discipline is the extraction of minerals from underneath, open pit, above or on the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure. With the process of Mineral extraction, some amount of waste and uneconomic material are generated which are the primary source of pollution in the vicinity of mines. Mining activities by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage to the environment both dur ...

Prospecting
Prospecting is the first stage of the geological analysis (followed by exploration) of a territory. It is the search for minerals, fossils, precious metals, or mineral specimens. It is also known as fossicking. Traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments. Modern prospecting also includes the use of geologic, geophysical, and geochemical tools to search for anomalies which can narrow the search area. Once an anomaly has been identified and interpreted to be a potential prospect direct observation can then be focused on this area. In some areas a prospector must also make claims, meaning they must erect posts with the appropriate placards on all four corners of a desired land they wish to prospect and register this claim before they may take samples. In other areas publicly held lands are open to prospecting without staking a mining claim. Historical methods The traditional methods of prospecting involved combi ...

Uraninite In Pegmatite (48002874171)
Uraninite, formerly pitchblende, is a radioactive, uranium-rich mineral and ore with a chemical composition that is largely UO2 but because of oxidation typically contains variable proportions of U3O8. Radioactive decay of the uranium causes the mineral to contain oxides of lead and trace amounts of helium. It may also contain thorium and rare-earth elements. Overview Uraninite used to be known as pitchblende (from '' pitch'', because of its black color, and ''blende'', from ''blenden'' meaning "to deceive", a term used by German miners to denote minerals whose density suggested metal content, but whose exploitation, at the time they were named, was either unknown or not economically feasible). The mineral has been known at least since the 15th century from silver mines in the Ore Mountains, on the German/Czech border. The type locality is the historic mining and spa town known as Joachimsthal, the modern day Jáchymov, on the Czech side of the mountains, where F. E. Brück ...

Geological Survey Of Canada
The Geological Survey of Canada (GSC; french: Commission géologique du Canada (CGC)) is a Canadian federal government agency responsible for performing geological surveys of the country, developing Canada's natural resources and protecting the environment. A branch of the Earth Sciences Sector of Natural Resources Canada, the GSC is the country's oldest scientific agency and was one of its first government organizations. History In September 1841, the Province of Canada legislature passed a resolution that authorized the sum of £1,500 sterling be granted to the government for the estimated expense of performing a geological survey of the province. In 1842, the Geological Survey of Canada was formed to fulfill this request.Christy Vodden (1992)No Stone Unturned: The First 150 years of the Geological Survey of Canada Geological Survey of Canada Web site William Edmond Logan was in Montreal at the time and made it known that he was interested in participating in this survey.

Eldorado Mining And Refining Limited
Eldorado Resources was a Canadian mining company active between 1926 and 1988. The company was originally established by brothers Charles and Gilbert LaBine as a gold mining enterprise in 1926, but transitioned to focus on radium in the 1930s and uranium beginning in the 1940s. The company was nationalized into a Crown corporation in 1943 when the Canadian federal government purchased share control. Eldorado Resources was merged with the Saskatchewan Mining Development Corporation in 1988 and the resulting entity was privatized as Cameco Corporation. The remediation of some mining sites and low-level nuclear waste continue to be overseen by the Government of Canada through Canada Eldor Inc., a subsidiary of the Canada Development Investment Corporation. History Eldorado was originally established as Eldorado Gold Mines but, after finding radioactive deposits at Great Bear Lake, Northwest Territories in 1930, the company transitioned to primarily mining radioactive materials.

Crown Corporation
A state-owned enterprise (SOE) is a government entity which is established or nationalised by the ''national government'' or ''provincial government'' by an executive order or an act of legislation in order to earn profit for the government, control monopoly of the private sector entities, provide products and services to citizens at a lower price and for the achievement of overall financial goals & developmental objectives in a particular country. The national government or provincial government has majority ownership over these ''state owned enterprises''. These ''state owned enterprises'' are also known as public sector undertakings in some countries. Defining characteristics of SOEs are their distinct legal form and possession of financial goals & developmental objectives (e.g., a state railway company may aim to make transportation more accessible and earn profit for the government), SOEs are government entities established to pursue financial objectives and devel ...
