Fission Mine
The Fission Mine, previously known as the Richardson Deposit, is a fluoride and uranium deposit in Cardiff, near Wilberforce, Ontario, Canada. Location and geology The mine is located two kilometres east of Wilberforce on lot four, concession 21 of Cardiff Township. The underground minerals are within pegmatite rock.Hugh S. Spence and R.K. Carnochan''The Wilberforce Radium Occurrence'', 1929, Mines Branch History Uranium was first discovered at the location in 1922, by prospector W. M. Richardson. His find was first called "the Richardson deposit" and later "the Fission property" In 1929, the mine was owned by Toronto company The Ontario Radium Corporation. The same year, Ontario Mine's Branch geologists Hugh S. Spence and R. K. Carnochan reported the several hundred pounds of radioactive materials found exceeded all known quantities of uranium in Canada and all ore bodies that they were aware of anywhere in the world. Combined with being close to the surface, and ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eldorado, Ontario
Eldorado is community in Madoc, Ontario (township), Madoc Township, in Ontario, Canada, with a 2019 population of 50. In 1866, it was the location of Ontario's first gold rush after Marcus Herbert Powell found gold on John Richardson's farm.ONTARIO'S FIRST GOLD MINE' (public sign), John Street and Ontario Highway 62, Highway 62, Archeological and Historic Sites Board of Ontario Location Eldorado is located six miles away from the centre of Madoc. History Municipal employee and part-time prospector Marcus Herbert Powell found gold on August 15, 1866, on a farm owned by John Richardson's. The town of Eldorado was founded in 1867. The same year the Richardson Mine went into operation. Despite higher expectations, Powell extracted about 100 ounces of gold, worth $1,500 to $2,000 at the time, but no further gold was found. Various other mines that had quickly opened, quickly closed. Demographics In 2019 the population of Eldorado was 50, down from 4,000 during the gold rus ...

Fluoride
Fluoride (). According to this source, is a possible pronunciation in British English. is an inorganic, monatomic anion of fluorine, with the chemical formula (also written ), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and minerals are important chemical reagents and industrial chemicals, mainly used in the production of hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Fluoride is the simplest fluorine anion. In terms of charge and size, the fluoride ion resembles the hydroxide ion. Fluoride ions occur on Earth in several minerals, particularly fluorite, but are present only in trace quantities in bodies of water in nature. Nomenclature Fluorides include compounds that contain ionic fluoride and those in which fluoride does not dissociate. The nom ...

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 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highlands East, Ontario
Highlands East is a township municipality located in Haliburton County, Ontario, Canada. History The township was incorporated in 2001 through the amalgamation of the former townships of Bancroft, Cardiff, Glamorgan, and Monmouth. Communities Cardiff is a former mining community; Bicroft and Dyno Mines opened in 1956 and closed several years later. The chief mineral being mined in Cardiff was uranium. Cardiff is located on Highway 118 between the towns of Bancroft and Haliburton. The Cardiff Elementary School is a small school. The community also has a Royal Canadian Legion hall, a Catholic and United church, an outdoor pool, which is popular during the summer, a post office, a municipal office, a library, and a skating rink that doubles as an outdoor basketball and floor hockey court. The entrance to the townsite, off of Highway 118, is marked by a large metal sculpture of a dragonfly. Gooderham is bordered on the south end of the municipality in proximity to the Irondale ...

National Center For Science Education
The National Center for Science Education (NCSE) is a not-for-profit membership organization in the United States whose stated mission is to educate the press and the public on the scientific and educational aspects of controversies surrounding the teaching of evolution and climate change, and to provide information and resources to schools, parents, and other citizens working to keep those topics in public school science education. Based in Oakland, California, it claims 4,500 members that include scientists, teachers, clergy, and citizens of varied religious and political affiliations. The Center opposes the teaching of religious views in science classes in America's public schools; it does this through initiatives such as Project Steve. The Center has been called the United States' "leading anti-creationist organization". The Center is affiliated with the American Association for the Advancement of Science. NCSE is currently a member of the National Coalition Against Censors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pegmatite
A pegmatite is an igneous rock showing a very coarse texture, with large interlocking crystals usually greater in size than and sometimes greater than . Most pegmatites are composed of quartz, feldspar, and mica, having a similar silicic composition to granite. However, rarer intermediate composition and mafic pegmatites are known. Many of the world's largest crystals are found within pegmatites. These include crystals of microcline, quartz, mica, spodumene, beryl, and tourmaline. Some individual crystals are over long. Most pegmatites are thought to form from the last fluid fraction of a large crystallizing magma body. This residual fluid is highly enriched in volatiles and trace elements, and its very low viscosity allows molecules to migrate rapidly to join an existing crystal rather than coming together to form new crystals. This allows a few very large crystals to form. While most pegmatites have a simple composition of minerals common in ordinary igneous rock, a few ...

Radon
Radon is a chemical element with the symbol Rn and atomic number 86. It is a radioactive, colourless, odourless, tasteless noble gas. It occurs naturally in minute quantities as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into various short-lived radioactive elements and lead. Radon itself is the immediate decay product of radium. Its most stable isotope, 222Rn, has a half-life of only 3.8 days, making it one of the rarest elements. Since thorium and uranium are two of the most common radioactive elements on Earth, while also having three isotopes with half-lives on the order of several billion years, radon will be present on Earth long into the future despite its short half-life. The decay of radon produces many other short-lived nuclides, known as "radon daughters", ending at stable isotopes of lead. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...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 ...
