Kayelekera Mine
Kayelekera uranium mine is an open cast uranium mine 52 kilometers west of the regional administrative and commercial centre Karonga in Malawi, Africa and was the country's largest mine. Production at the mine has been paused since February 2014, due to a fall in global uranium prices. History Kayelekera was owned 100% by Paladin (Africa) Limited (PAL), an 85% subsidiary of Australian and Canadian listed Paladin Energy and in July 2009, Paladin issued 15% of the equity in Paladin (Africa) Ltd to the Government of MalawiAnnual Report and Financial Statements Paladin Energy Ltd. 2009-01-01. Retrieved 2016-09-22. under the terms of the Mining Development Agreement signed between PAL and the Government in February 2007. The mine was officially opened on 17 April 200 ...

Malawi
Malawi (; or aláwi Tumbuka: ''Malaŵi''), officially the Republic of Malawi, is a landlocked country in Southeastern Africa that was formerly known as Nyasaland. It is bordered by Zambia to the west, Tanzania to the north and northeast, and Mozambique to the east, south and southwest. Malawi spans over and has an estimated population of 19,431,566 (as of January 2021). Malawi's capital (and largest city) is Lilongwe. Its second-largest is Blantyre, its third-largest is Mzuzu and its fourth-largest is its former capital, Zomba. The name ''Malawi'' comes from the Maravi, an old name for the Chewa people who inhabit the area. The country is nicknamed "The Warm Heart of Africa" because of the friendliness of its people. The part of Africa now known as Malawi was settled around the 10th century by migrating Bantu groups . Centuries later, in 1891, the area was colonised by the British and became a protectorate of the United Kingdom known as Nyasaland. In 1953, it became ...

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] |
Karonga
Karonga is a township in the Karonga District in Northern Region of Malawi. Located on the western shore of Lake Nyasa, it was established as a slaving centre sometime before 1877. As of 2018 estimates, Karonga has a population of 61,609. History Pre-historic tools and remains of hominids discovered in Malawi's remote northern district of Karonga provides further proof that the area could be the cradle of humankind. Professor Friedemann Schrenk of the Goethe University in Frankfurt told Reuters News that two students working on the excavation site in September 2009 had discovered prehistoric tools and a tooth of a hominid. "This latest discovery of prehistoric tools and remains of hominids provides additional proof to the theory that the Great Rift Valley of Africa and perhaps the excavation site near Karonga can be considered the cradle of humankind." Schrenk said. The site also contains some of the earliest dinosaurs which lived between 100 million and 140 million years ...

Paladin Energy
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. As of February 2018, Paladin is in the process of restructuring, having filed for insolvency in July 2017. History Uranerz Australia started operations in Perth, Western Australia, in 1970 with John Borshoff, Paladin's managing director/CEO, serving as Chief executive from 1986 to 1991. Uranerz, the Australian arm of German-based uranium mining house Uranerzbergbau, explored throughout Australia, New Zealand, and Africa, focusing primarily on uranium. When Uranerz decided to close its Australian operations, John Borshoff acquired its extensive proprietary databases, which subsequently formed the nucleus for the public float of Pala ...

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] |
Uranium Oxide
Uranium oxide is an oxide of the element uranium. The metal uranium forms several oxides: * Uranium dioxide or uranium(IV) oxide (UO2, the mineral uraninite or pitchblende) * Diuranium pentoxide or uranium(V) oxide (U2O5) * Uranium trioxide or uranium(VI) oxide (UO3) * Triuranium octoxide (U3O8), the most stable uranium oxide; yellowcake typically contains 70 to 90 percent triuranium octoxide) * Uranyl peroxide (UO2O2 or UO4) * Amorphous uranium(VI) oxide (''Am''-U2O7) Uranium dioxide is oxidized in contact with oxygen Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as wel ... to form triuranium octoxide. :3 UO2 + O2 → U3O8; at 700 °C (970 K) Preparation 38 During World War II, "Preparation 38" was the codename for uranium oxide used by German scientists.

Walvis Bay
Walvis Bay ( en, lit. Whale Bay; af, Walvisbaai; ger, Walfischbucht or Walfischbai) is a city in Namibia and the name of the bay on which it lies. It is the second largest city in Namibia and the largest coastal city in the country. The city covers a total area of of land. The bay is a safe haven for sea vessels because of its natural deepwater harbour, protected by the Pelican Point sand spit, being the only natural harbour of any size along the country's coast. Being rich in plankton and marine life, these waters also drew large numbers of southern right whales, attracting whalers and fishing vessels. A succession of colonists developed the location and resources of this strategic harbour settlement. The harbour's value in relation to the sea route around the Cape of Good Hope had caught the attention of world powers since it was discovered by the outside world in 1485. This explains the complicated political status of Walvis Bay down the years. The town is situated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kanyika Mine
The Kanyika mine is an open pit mine which extracts niobium ore from a large deposit located in northern Malawi in the Northern Region, about 250 kilometers north of Lilongwe. It will be the second-largest mining operation in the country, behind the Kayelekera mine. Kanyika represents one of the largest niobium mineral resource in Malawi having estimated resources of 60 million tonnes of ore grading 0.29% niobium metal. The mine is the main project of the Australia-based ''Globe Metals & Mining Ltd.'' History Prospecting began in 2006, when Globe Metals received an Exclusive Prospecting License from the Malawian government. The project was initially planned to be developed as a joint venture between globe and the South Africa based engineering firm ''Thuthuka Group''. In 2011, Globe Metals was joined by the Nanjing based state owned enterprise ''East China Mineral Exploration and Development Bureau'', which acquired a 51% stake in Globe Metals based on a $47 million investment.
