Langer Heinrich Mine
The Langer Heinrich Mine (LHM) is a large open pit mine located in the western part of Namibia in the Erongo Region. Langer Heinrich represents one of the largest uranium reserves in Namibia having estimated reserves of 57,000 tonnes of ore grading 0.055% uranium. The Langer Heinrich Mine is currently owned by Paladin Energy Ltd with a 75% stake and CNNC Overseas Uranium Holding Ltd with a 25% stake. Paladin Energy sold the 25% to the Chinese National Nuclear Corporation (CNNC) in 2014 for a reported $190 million. The mine is under care and maintenance since 2018. History The uranium deposit was discovered at the Langer Heinrich Mine in 1973, however the mine only commenced uranium mining operations in 2007 after the mine had been unused for nearly 7 years. Development In 2008, Paladin Energy announced that the Langer Heinrich Mine had achieved its production target for December 2007. In 2008 though, two incidents occurred that halted production: The open pit was flooded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paladin Energy Ltd
Paladin Energy Ltd is a Western Australian based uranium production company. It currently has one operating mine in Africa; the Langer Heinrich Mine (LHM) in Namibia. Paladin was listed on the Australian, OTC and Namibian Stock Exchanges, as well as the Munich, Berlin, Stuttgart and Frankfurt Exchanges. It also owns deposits in Western Australia. History In February 2009, Paladin completed the takeover of Fusion Resources, adding the Duke Batman and Honey Pot deposits to the existing Mount Isa project area. The capacity of the LHM operation has been successfully expanded to a production rate of 5.2Mlb per annum. According to diplomatic cables leaked in 2010, BHP Billiton attempted to lobby the Australian government in order to block the Aluminium Corporation of China (Chinalco) investment in Rio Tinto. In 2012, Paladin joined forces with Rio Tinto to block the sales of BHP Billiton's Australian uranium deposit to Canadian mining company, Cameco. Founder of Paladin, John ...

Uranium
Uranium is a chemical element; it has chemical symbol, 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 radioactive decay, radioactively decays, usually by emitting an alpha particle. The half-life of this decay varies between 159,200 and 4.5 billion years for different isotopes of uranium, isotopes, making them useful for dating the age of the Earth. 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 primordial nuclide, 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 notation#Parts-per expressions, parts per million in soil, ... [...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 that extracts rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin. In contrast, deeper mineral deposits can be reached using underground mining. Open-pit mining is considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners' health, as well as damage to the ecological land and water. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used. Extraction Miners typically drill a series of test holes to locate an underground ore body. From ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namibia
Namibia, officially the Republic of Namibia, is a country on the west coast of Southern Africa. Its borders include the Atlantic Ocean to the west, Angola and Zambia to the north, Botswana to the east and South Africa to the south; in the northeast, approximating a quadripoint, Zimbabwe lies less than 200 metres (660 feet) away along the Zambezi, Zambezi River near Kazungula, Zambia. Namibia's capital and largest city is Windhoek. Namibia is the driest country in sub-Saharan Africa, and has been inhabited since prehistoric times by the Khoekhoe, Khoi, San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. From 1600 the Ovambo people#History, Ovambo formed kingdoms, such as Ondonga and Oukwanyama. In 1884, the German Empire established rule over most of the territory, forming a colony known as German South West Africa. Between 1904 and 1908, German troops waged a punitive ...

Care And Maintenance
Care and maintenance is a term used in the mining industry to describe processes and conditions on a closed mine site at which there is the potential to recommence operations at a later date. During the 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 provide 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heap Leaching
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to In situ leach, in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas ''in situ'' mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used in modern large-scale mining operations as it produces the desired concentrates at a lower cost compared to conventional processing methods such as flotation, agitation, and vat leaching. Additionally, dump leaching is an essential part of most copper mining operations and determines the quality grade of the produced material along with other factors Due to the profitability that the dump leaching has on the mining process, i.e. it can contri ...
