Uranium In Africa
Uranium production is an important part of the African economy, with Niger, Namibia and South Africa creating up to 18% of the world's annual production. Many African countries produce uranium or have untapped uranium ore deposits.

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] |
Mounana
Mounana is a town in Gabon. It lies on the N3 road and from 1958 until the 1990s was a major uranium mining centre. The mine is now closed, and it is now primarily a centre for agriculture Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people .... According to the 1993 census it had a population of 6,372 and in 2013 it had an estimated population of 12,437.

Arlit
Arlit is an industrial town and capital of the Arlit Department of the Agadez Region of northern-central Niger, built between the Sahara Desert and the eastern edge of the Aïr Mountains. It is 200 km south by road from the border with Algeria. As of 2011, the commune had a total population of 112,432 people. Uranium industry Founded in 1969 following the discovery of uranium, it has grown around the mining industry, developed by the French government. Two large uranium mines, at Arlit and nearby Akouta, are exploited by open top strip mining. One open pit mine was built in 1971 by the National Mining Company of Niger, SOMAIR. The Second open pit mine, as well as a third underground mine, was built by the French Compagnie Minière d'Akouta (or COMINAK). All the ore from both is now processed and transported by a French company Orano Cycle, a holding of the Orano group, itself a state owned operation of the French ''Commissariat à l'énergie atomique'' (CEA).

Agadez Region
Agadez Region is one of the seven regions of Niger. At , it covers more than half of Niger's land area, and is the largest region in the country, as well as the largest African state subdivision. The capital of the department is Agadez. History The region is a centre for palaeontology, with numerous dinosaur skeletons being found here, including the ''Ouranosaurus nigeriensis''. Cave painting and the remains of ancient human settlements are also located here. Tuareg peoples began migrating to the region from the mid-8th century. From the mid-15th century to the early 20th, much of the region was under the control of the Sultanate of Agadez, except for a period when the area came under the rule of the Songhai Empire in the 1500s. The region suffered with the advent of French colonialism as power shifted away to the southwest; Tuareg disaffection with French rule resulted in the Kaocen revolt in 1916–17. This process continued following Niger's independence in 1960; local Tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aïr Mountains
The Aïr Mountains or Aïr Massif ( tmh, Ayăr; Hausa: Eastern ''Azbin'', Western ''Abzin'') is a triangular massif, located in northern Niger, within the Sahara. Part of the West Saharan montane xeric woodlands ecoregion, they rise to more than and extend over . Lying in the midst of desert north of the 17th parallel, the Aïr plateau, with an average altitude between , forms an island of Sahel climate which supports a wide variety of life, many pastoral and farming communities, and dramatic geological and archaeological sites. There are notable archaeological excavations in the region that illustrate the prehistoric past of this region. The endangered African wild dog (''Lycaon pictus'') once existed in this region, but may now be extirpated due to human population pressures in this region. Geology The Precambrian to Cenozoic Aïr Mountains consist of peralkaline granite intrusions which appear dark in colour (unusual since most granitic masses are light-ton ...

Areva NC
Orano Cycle, formerly COGEMA (''Compagnie générale des matières nucléaires'') and Areva NC, is a French nuclear company. It is the main subsidiary of Orano S.A. It is an industrial group active in all stages of the uranium fuel cycle, including uranium mining, conversion, enrichment, spent fuel reprocessing, and recycling. The company was originally created in 1976. In 2001, it became part of Areva; its name was changed to ''Areva NC'' in March 2006.

Valerie Plame Affair
The Plame affair (also known as the CIA leak scandal and Plamegate) was a political scandal that revolved around journalist Robert Novak's public identification of Valerie Plame as a covert Central Intelligence Agency officer in 2003. In 2002, Plame wrote a memo to her superiors in which she expressed hesitation in recommending her husband, former diplomat Joseph C. Wilson, to the CIA for a mission to Niger to investigate claims that Iraq had arranged to purchase and import uranium from the country, but stated that he "may be in a position to assist". After President George W. Bush stated that "Saddam Hussein recently sought significant quantities of uranium from Africa" during the run-up to the 2003 invasion of Iraq, Wilson published a July 2003 op-ed in ''The New York Times'' stating his doubts during the mission that any such transaction with Iraq had taken place. A week after Wilson's op-ed was published, Novak published a column in ''The Washington Post'' which mentioned cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trekkopje
Trekkopje is a mountain in the Erongo Region of Namibia, north-east of Swakopmund on the road to Usakos. History The Swakopmund–Windhoek railway line goes past the mountain. When the Swakopmund-Windhoek line was converted from to in 1910, a patch of railway west of Karibib was not completed, and passengers and load had to be moved twice, in Karibib and at Trekkopje. Today the railway station no longer stands, and the railway stop is not in use anymore, either. Trekkopje was the site of the Battle of Trekkopjes, a World War I battle aimed at preventing South African troops from rebuilding the railway line. A war cemetery, ''Trekkopje Cemetery'' () features 16 graves of railway protection troops from this battle. Trekkopje mine Trekkopje mine, a currently unused Uranium mine of Areva is situated about north of the mountain. Trekkopje desalination plant is in turn named after the mine, as it was built to provide the mine with water. The desalination plant is situated at ...
