Katangese
Katanga was one of the four large provinces created in the Belgian Congo in 1914. It was one of the eleven provinces of the Democratic Republic of the Congo between 1966 and 2015, when it was split into the Tanganyika, Haut-Lomami, Lualaba, and Haut-Katanga provinces. Between 1971 and 1997 (during the rule of Mobutu Sese Seko when Congo was known as Zaire), its official name was Shaba Province. Katanga's area encompassed . Farming and ranching are carried out on the Katanga Plateau. The eastern part of the province is considered to be a rich mining region, which supplies cobalt, copper, tin, radium, uranium, and diamonds. The region's former capital, Lubumbashi, is the second-largest city in the Congo. History Copper mining in Katanga dates back over 1,000 years, and mines in the region were producing standard-sized ingots of copper for international transport by the end of the 10th century CE. In the 1890s, the province was beleaguered from the south by Cecil Rhodes' Nort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lubumbashi
Lubumbashi (former names: ( French), (Dutch)) is the second-largest city in the Democratic Republic of the Congo, located in the country's southeasternmost part, along the border with Zambia. The capital and principal city of the Haut-Katanga Province, Lubumbashi is the center of mining in the region, acting as a hub for many of the country's largest mining companies. No definite population figures are available, but the population of the city's urban area is estimated to be around 2,584,000 in 2021. History Élisabethville under Belgian rule The Belgian government established the modern-day government in the city of ''Élisabethville'' (sometimes Elizabethville, both in French, or Elisabethstad in Dutch) in 1910, named in honour of Queen Elisabeth, consort to King Albert I of the Belgians. By that time, the government had taken over the colony from King Leopold II, and renamed it as the Belgian Congo. This site was chosen by Vice-Governor-General Emile Wangermée becaus ...

Zaire
Zaire (, ), officially the Republic of Zaire (french: République du Zaïre, link=no, ), was a Congolese state from 1971 to 1997 in Central Africa that was previously and is now again known as the Democratic Republic of the Congo. Zaire was, by area, the third-largest country in Africa (after Sudan and Algeria), and the 11th-largest country in the world. With a population of over 23 million inhabitants, Zaire was the most-populous officially Francophone country in Africa, as well as one of the most populous in Africa. The country was a one-party totalitarian military dictatorship, run by Mobutu Sese Seko and his ruling Popular Movement of the Revolution party. Zaire was established following Mobutu's seizure of power in a military coup in 1965, following five years of political upheaval following independence from Belgium known as the Congo Crisis. Zaire had a strongly centralist constitution, and foreign assets were nationalized. The period is sometimes referred to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Msiri

Northern Rhodesia
Northern Rhodesia was a British protectorate in southern Africa, south central Africa, now the independent country of Zambia. It was formed in 1911 by Amalgamation (politics), amalgamating the two earlier protectorates of Barotziland-North-Western Rhodesia and North-Eastern Rhodesia.''Commonwealth and Colonial Law'' by Kenneth Roberts-Wray, London, Stevens, 1966. P. 753 It was initially administered, as were the two earlier protectorates, by the British South Africa Company (BSAC), a chartered company, on behalf of the British Government. From 1924, it was administered by the British Government as a protectorate, under similar conditions to other British-administered protectorates, and the special provisions required when it was administered by BSAC were terminated.Northern Rhodesia Order in Council, 1924, S.R.O. 1924 No. 324, S.RO. & S.I.

Cecil Rhodes
Cecil John Rhodes (5 July 1853 – 26 March 1902) was a British mining magnate and politician in southern Africa who served as Prime Minister of the Cape Colony from 1890 to 1896. An ardent believer in British imperialism, Rhodes and his British South Africa Company colonised the southern African territory of Rhodesia (now Zimbabwe and Zambia), which the company named after him in 1895. South Africa's Rhodes University is also named after him. He also devoted much effort to realising his vision of a Cape to Cairo Railway through British territory. Rhodes set up the provisions of the Rhodes Scholarship, which is funded by his estate. The son of a vicar, Rhodes was born at Netteswell House, Bishop's Stortford, Hertfordshire. A sickly child, he was sent to South Africa by his family when he was 17 years old in the hope that the climate might improve his health. He entered the diamond trade at Kimberley in 1871, when he was 18, and, thanks to funding from Rothschild & Co, beg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ingots
An ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing. In steelmaking, it is the first step among semi-finished casting products. Ingots usually require a second procedure of shaping, such as cold/hot working, cutting, or milling to produce a useful final product. Non-metallic and semiconductor materials prepared in bulk form may also be referred to as ingots, particularly when cast by mold based methods. Precious metal ingots can be used as currency (with or without being processed into other shapes), or as a currency reserve, as with gold bars. Types Ingots are generally made of metal, either pure or alloy, heated past its melting point and cast into a bar or block using a mold chill method. A special case are polycrystalline or single crystal ingots made by pulling from a molten melt. Single crystal Single crystal ingots (called boules) of materials are grown (crystal growth) using methods such as the Czoc ...

Copper Mining
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of mines and smelters was more typical in the 19th and early 20th centuries, when smaller smelters could be economic. The sulfide concentrates are typically smelted in such furnaces as the Outokumpu or Inco f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamond
Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the Chemical stability, chemically stable form of carbon at Standard conditions for temperature and pressure, room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest Scratch hardness, hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of lattice defect, defects or impurities (about one per million of lattice atoms) color diamond blue (bor ... [...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] |
