Arlit Mine
The Arlit mine is a large mine located near Arlit, in the northern part of Niger in Agadez Region. Arlit represents one of the largest uranium reserves in Niger having estimated reserves of 47.5 million tonnes of ore grading 0.014% 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 ....

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] |

Privately-held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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).
