Bwana Mkubwa
Bwana Mkubwa (or Bwana M'kubwa; meaning "big chief"; or "great master") is a settlement and a mine in Copperbelt Province, Zambia. It is the oldest mine in Zambia's Copperbelt region. As a settlement with no municipal status, it became a locale due to the abundant copper deposits found in the area. Today, it is part of Ndola. Etymology Several versions of the origin of the name have been given. Mostly likely, William Collier and Jack Donohoe, who were led to the ancient workings, named the mining area "Bwana Mkubwa" after Francis Emilius Fletcher Jones, Native Commissioner, who was known to the locals as the 'Bwana Mkubwa'. Geography Bwana Mkubwa is located at the southern extension of the Zambian Copperbelt, near the Kafue River, east of the T3 Highway. The city centre of Ndola is to the northwest. It is in the Bwana Mkubwa Protected Forest Area at an elevation of . It is located in the Constituency of the same Name. Politics The town is represented in the National Assembly ...

Provinces Of Zambia
Zambia is divided into 10 provinces for administrative purposes. Each province is headed by a minister appointed by the President and there are ministries of central government for each province. The administrative head of each province is the Permanent Secretary, appointed by the President. There are Deputy Permanent Secretary, heads of government departments and civil servants at the provincial level. Provinces are further divided into districts and almost all the district headquarters are the same as the district names. Each of the 116 districts in the 10 provinces has a council which is headed by an elected representative, called councilor. Each councilor holds office for five years. Each council is responsible for raising and collecting local taxes and the budgets of the council are audited and submitted every year after the annual budget. Zambia has predominantly rural provinces and hence there are only three municipal councils. The government stipulates 63 different funct ...

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. Rev VIII, 154 Although under the BSAC charter it had features of a charter colony, the BSAC's treaties with local rulers, and British legisla ...

Sulphuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid ( Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula . It is a colorless, odorless and viscous liquid that is miscible with water. Pure sulfuric acid does not exist naturally on Earth due to its strong affinity to water vapor; it is hygroscopic and readily absorbs water vapor from the air. Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals, since it is an oxidant with powerful dehydrating properties. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid, but to the contrary dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is released; thus the reverse procedure of adding water to the acid should not be performed since the heat released may boil ...

Copper Cathode
A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic ''CCD'' for ''Cathode Current Departs''. A conventional current describes the direction in which positive charges move. Electrons have a negative electrical charge, so the movement of electrons is opposite to that of the conventional current flow. Consequently, the mnemonic ''cathode current departs'' also means that electrons flow ''into'' the device's cathode from the external circuit. For example, the end of a household battery marked with a + (plus) is the cathode. The electrode through which conventional current flows the other way, into the device, is termed an anode. Charge flow Conventional current flows from cathode to anode outside of the cell or device (with electrons moving in the opposite direction), regardless of the cell or device type and operating mode. Cathode polarity with respect to the anode can be positive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernest Oppenheimer

Malachite
Malachite is a copper carbonate hydroxide mineral, with the formula Cu2CO3(OH)2. This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation. Individual crystals are rare, but occur as slender to acicular prisms. Pseudomorphs after more tabular or blocky azurite crystals also occur. Etymology and history The stone's name derives (via la, molochītis, frm, melochite, and Middle English ''melochites'') from Greek Μολοχίτης λίθος ''molochites lithos'', "mallow-green stone", from μολόχη ''molochē'', variant of μαλάχη ''malāchē'', "mallow". The mineral was given this name due to its resemblance to the leaves of the mallow plant. Malachite was mined from deposits near the Isthmus of Suez and the Sinai as early as 4000 BCE. It wa ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nkana
Nkana is a section of the city of Kitwe, Copperbelt Province, Zambia which started off in the early part of the 20th century as a railway station to support the growing complex of copper mining operations. It was named after Chief Nkana, the local traditional ruler. The copper mines of Nkana (South Ore Body, Nkana Mine and Mindola Shaft) were originally owned by the Anglo-American Corporation of South Africa.

Susman Brothers
Susman Brothers was a business partnership that united brothers Elie Susman and Harry Susman after they crossed the Zambezi river in 1901. The brothers were Jewish businessmen from Rietavas, western part of Russian Empire, now Lithuania. They founded, owned, and operated several large businesses in Africa. Elie Susman, the younger of the two, was the founder of Susman Brothers. However, it was not until 1907 that the business name of "E. Susman" was changed to "Susman Brothers". Retail stores in Northern Rhodesia (now Zambia) date to the Susman brothers. Their business empire lasted over a century by overcoming logistical difficulties, physically challenging obstacles, and political changes. They developed an extensive trading, transport and ranching network, which stretched from Botswana to the Democratic Republic of the Congo. Though they operated in many different places, their main focus was always the country now known as Zambia. Early years Harry Susman worked as a pedd ...
