Trekkopje Mine
The Trekkopje mine is a shallow open pit mine which has been under care and maintenance since 2012. It is located at Trekkopje in the western part of Namibia in Erongo Region. Trekkopje represents one of the largest uranium reserves in Namibia, having estimated reserves of 340 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 ....

Erongo Region
Erongo is one of the 14 regions of Namibia. The capital is Swakopmund. It is named after Mount Erongo, a well-known landmark in Namibia and in this area. Erongo contains the municipalities of Walvis Bay, Swakopmund, Henties Bay and Omaruru, as well as the towns Arandis, Karibib and Usakos. All the main centres within this region are connected by paved roads. The Erongo Region had a population of 150,809 in 2011. As of 2020, it had 119,784 registered voters. In the west, Erongo has a shoreline on the Atlantic Ocean. On land, it borders the following regions: * Kunene - north *Otjozondjupa - northeast *Khomas - southeast *Hardap - south Economy and infrastructure Various mining operations occur within this region at places such as Navachab and on a smaller scale at places surrounding Uis and the desert area. Karibib also has a marble industry. Walvis Bay, fully incorporated into the Erongo Region in 1994, is the principal home of Namibia's fishing industry. Walvis Bay also b ...

Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although Kazungula, it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi, Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Areva
Areva S.A. is a French multinational group specializing in nuclear power headquartered in Courbevoie, France. Before its 2016 corporate restructuring, Areva was majority-owned by the French state through the French Alternative Energies and Atomic Energy Commission (54.37%), Banque publique d'investissement (3.32%), and Agence des participations de l'État (28.83%). Électricité de France, of which the French government has a majority ownership stake, owned 2.24%; Kuwait Investment Authority owned 4.82% as the second largest shareholder after the French state. As a part of the restructuring program following its insolvency, Areva sold out or discontinued its renewable energy businesses, sold its reactors business subsidiary Areva NP (now: Framatome) to EDF and its nuclear propulsion and research reactors subsidiary Areva TA (now: Technicatome) to Agence des participations de l'État, and separated its nuclear cycle business into a separate company New Areva (later: Orano).

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] |
Open Pit
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting eac ...

Care And Maintenance
Care and maintenance is a term used in the mining industry to describe processes and conditions on a closed minesite where there is potential to recommence operations at a later date. During a care and maintenance phase, production is stopped but the site is managed to ensure it remains in a safe and stable condition. Causes The mine might be considered to be temporarily unviable, due to current economic conditions or unfavourable resource prices, which are expected to improve at a later date. Declining ore grades at some mines can also be a reason for care and maintenance announcements. In some cases controlling interest companies decide not to further funding for subsidiary operations. During closure While the mine is closed, a care and maintenance program will manage environmental risks associated with tailings dumps, hazardous materials and open and underground pits. Care of idle plant and machinery will also be included in the program. Public health and safety consideratio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Nuclear Association
World Nuclear Association is the international organization that promotes nuclear power and supports the companies that comprise the global nuclear industry. Its members come from all parts of the nuclear fuel cycle, including uranium mining, uranium conversion, uranium enrichment, nuclear fuel fabrication, plant manufacture, transport, and the disposition of spent nuclear fuel, used nuclear fuel as well as electricity generation itself. Together, World Nuclear Association members are responsible for 70% of the world's nuclear power as well as the vast majority of world uranium, conversion and Enriched uranium, enrichment production. The Association says it aims to fulfill a dual role for its members: Facilitating their interaction on technical, commercial and policy matters and promoting wider public understanding of nuclear technology. It has a secretariat of around 30 staff. The Association was founded in 2001 on the basis of the Uranium Institute, itself founded in 1975. ...

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 ...
