ZISCO Steel
Zimbabwe Iron and Steel Company is the largest steel works in Zimbabwe. It is located just outside Kwekwe, in Redcliff, Kwekwe District. Over the years the company has faced many operational problems and corruption scandals. History In 1942, the colonial government founded the Rhodesian Iron and Steel Commission (Riscom). It was sited at the steel plant at Redcliff, to develop the huge iron and limestone deposits nearby. In 1957, it changed its name to the Rhodesian Iron and Steel Company (Risco). It suffered from a lack of experienced personnel and low level of production which meant high unit costs. In 1954, a debt of 1.7 million pounds sterling had to been written off as irrecoverable. In 1956, the loss-making situation was turned into a profit-making situation due to the formation of the Federation of Rhodesia and Nyasaland and the denationalisation of the industry. In 1956, iron ore output from the company was 127,954 tons. By 1957, this had doubled to 257,166 tons.Leonard To ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel Works
A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished casting products are made from molten pig iron or from scrap. History Since the invention of the Bessemer process, steel mills have replaced ironworks, based on puddling or fining methods. New ways to produce steel appeared later: from scrap melted in an electric arc furnace and, more recently, from direct reduced iron processes. In the late 19th and early 20th centuries the world's largest steel mill was the Barrow Hematite Steel Company steelworks located in Barrow-in-Furness, United Kingdom. Today, the world's largest steel mill is in Gwangyang, South Korea. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zimbabwe
Zimbabwe (), officially the Republic of Zimbabwe, is a landlocked country located in Southeast Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa to the south, Botswana to the south-west, Zambia to the north, and Mozambique to the east. The capital and largest city is Harare. The second largest city is Bulawayo. A country of roughly 15 million people, Zimbabwe has 16 official languages, with English, Shona language, Shona, and Northern Ndebele language, Ndebele the most common. Beginning in the 9th century, during its late Iron Age, the Bantu peoples, Bantu people (who would become the ethnic Shona people, Shona) built the city-state of Great Zimbabwe which became one of the major African trade centres by the 11th century, controlling the gold, ivory and copper trades with the Swahili coast, which were connected to Arab and Indian states. By the mid 15th century, the city-state had been abandoned. From there, the Kingdom of Zimbabwe was established, fol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Federation Of Rhodesia And Nyasaland
The Federation of Rhodesia and Nyasaland, also known as the Central African Federation or CAF, was a colonial federation that consisted of three southern African territories: the Self-governing colony, self-governing British colony of Southern Rhodesia and the British protectorates of Northern Rhodesia and Nyasaland. It existed between 1953 and 1963. The Federation was established on 1 August 1953, with a Governor-General of the Federation of Rhodesia and Nyasaland, Governor-General as the Queen's representative at the centre. The constitutional status of the three territories a self-governing Colony and two Protectorates was not affected, though certain enactments applied to the Federation as a whole as if it were part of Her Majesty's dominions and a Colony. A novel feature was the African Affairs Board, set up to safeguard the interests of Africans and endowed with statutory powers for that purpose, particularly in regard to discriminatory legislation.

Lancaster House Agreement
The Lancaster House Agreement, signed on 21 December 1979, declared a ceasefire, ending the Rhodesian Bush War; and directly led to Rhodesia achieving internationally recognised independence as Zimbabwe. It required the full resumption of direct British rule, nullifying the Unilateral Declaration of Independence of 1965. British governance would be strictly prescribed to the duration of a proposed election period followed by a formal power transfer back to a recognised, sovereign state. Constitutional instruments would thus be transferred from the British state to a popularly elected government, under an unqualified universal franchise vote. Crucially, the political wings of the black nationalist groups ZANU and ZAPU, who had been waging an increasingly violent insurgency, would be permitted to stand candidates in the forthcoming elections. This was however conditional to compliance with the ceasefire and the verified absence of voter intimidation. The Agreement would lead t ...

Blast Furnaces
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. ''Blast'' refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace, fuel ( coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and waste gases (flue gas) exiting from the top of the furnace. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process. In contrast, air furnaces (such as reverberator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (, 72.4% Fe), hematite (, 69.9% Fe), goethite (, 62.9% Fe), limonite (, 55% Fe) or siderite (, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the ''Financial Times'' quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity, except perhaps oil". Sources Metallic iron is virtually unknown on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel Companies Of Zimbabwe
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iron () is a chemical element with Symbol (chemistry), symbol Fe (from la, Wikt:ferrum, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 element, group 8 of the periodic table. It is, Abundance of the chemical elements#Earth, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer core, outer and inner core. It is the fourth most common abundance of elements in Earth's crust, element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or Metallurgical furnace, furnaces capable of reaching or higher, about higher than that required to smelting, smelt copper.
