Alaska, Zimbabwe
Alaska is a small town in central northern Zimbabwe in Makonde District, Mashonaland West Province. Location The town is located approximately west of the city of Chinhoyi, the location of the district and provincial headquarters. Approximately to the northeast of Alaska are the Chinhoyi Caves in the Chinhoyi Caves National Park, a local tourist attraction. The town sits at an elevation of , above sea level. History Alaska grew up around the eponymous Alaska Mine, where pre-colonial miners are believed to have mined about a million tonnes of ore. Messina Transvaal Development Company (MTD) started producing copper in 1959 and the Mine closed in 1977. MTD built a smelter nearby in 1966 and a Refinery in 1980. Other mines in the district also produced copper flotation concentrate which was brought to Alaska for smelting and refining. These Mines included MTD's Mhangura copper mine in Mhangura and Shackleton mine near Lions Den. The smelter and refinery closed in late 2000 by wh ...

Flag Of Zimbabwe
The national flag of Zimbabwe consists of seven even horizontal stripes of green, gold, red and black with a white triangle containing a red five-pointed star with a Zimbabwe Bird. The present design was adopted on 18 April 1980. The soapstone bird featured on the flag represents a statuette of a bird found at the ruins of Great Zimbabwe. The bird symbolises the history of Zimbabwe; the red star beneath it officially stands for the nation's aspirations but is commonly thought to symbolise socialism, and the revolutionary struggle for freedom and peace. The design is based on the flag of Zimbabwe's ruling party, the Zimbabwe African National Union – Patriotic Front. History The country now known as Zimbabwe was formally known as Southern Rhodesia from 1895 to 1980—although simply Rhodesia was used locally between 1964 until June 1979 after Northern Rhodesia obtained its independence—and then Zimbabwe Rhodesia between June and December 1979. Southern Rhodesia achieve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Populated Places In Mashonaland West Province
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations. Ecology In ecology, a population is a group of organisms of the same species who inhabit the same particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with ind ...

Economy Of Zimbabwe
The economy of Zimbabwe mainly relies on the tertiary sector of the economy, also known as the service sector of the economy, which makes up to 60% of total GDP as of 2017. Zimbabwe has the second biggest Informal economy in the world as a percentage of its economy, with a score of 60.6%.https://www.herald.co.zw/zim-has-worlds-second-largest-informal-economy-imf/ /ref> Agriculture and mining largely contribute to exports. After continuous negative growth between 1999 and 2008, the economy of Zimbabwe grew at a meteoric annual rate of 34% from 2008 to 2013, rendering it the fastest-growing economy in the world. Its economy then stagnated again through 2020, before seeing another extremely sharp increase (45%) in the most recent year. The country has reserves of metallurgical-grade Chromite. Other commercial mineral deposits include Coal, asbestos, copper, nickel, gold, platinum and Iron ore. Current economic conditions In 2000, Zimbabwe planned a land redistribution act to co ...

Refining
{{Unreferenced, date=December 2009 Refining (also perhaps called by the mathematical term affining) is the process of purification of a (1) substance or a (2) form. The term is usually used of a natural resource that is almost in a usable form, but which is more useful in its pure form. For instance, most types of natural petroleum will burn straight from the ground, but it will burn poorly and quickly clog an engine with residues and by-products. The term is broad, and may include more drastic transformations, such as the reduction of ore to metal (for which see Refining (metallurgy)). The refining of liquids is often accomplished by distillation or fractionation; this process is useful, for example, for isolating different fractions of petroleum. Gases can be refined in this way as well, by being cooled and/or compressed until they liquefy. Gases and liquids can also be refined by extraction with a selective solvent that dissolves away either the substance of interest, or the ...

Smelting
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures due to the lower potential energy of the bonds in carbon dioxide (). Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal element as a product. The carbon source is oxidized in two stages. First, the carbon (C) combusts with oxygen (O2) in the air to produce carbon monoxide (CO). Second, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Humid Subtropical Climate
A humid subtropical climate is a zone of climate characterized by hot and humid summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates. It is also known as warm temperate climate in some climate classifications. Under the Köppen climate classification, ''Cfa'' and ''Cwa'' climates are either described as humid subtropical climates or warm temperate climates. This climate features mean temperature in the coldest month between (or ) and and mean temperature in the warmest month or higher. However, while some climatologists have opted to describe this climate type as a "humid subtropical climate", Köppen himself never used this term. The humid subtropical climate classification was officially created under the Trewartha climate classification. In this classification, climates are termed humid subtropical when the ...

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] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Africa Time
Central Africa Time or CAT, is a time zone used in central and southern Africa. Central Africa Time is two hours ahead of Coordinated Universal Time ( UTC+02:00), which is the same as the adjacent South Africa Standard Time, Egypt Standard Time, Eastern European Time, Kaliningrad Time and Central European Summer Time. As this time zone is in the equatorial and tropical regions, there is little change in day length throughout the year and so daylight saving time is not observed. Central Africa Time is observed by the following countries: * * * (eastern side only) * * * * * * * * The following countries in Africa also use an offset of UTC+02:00 all-year round: * (observes Egypt Standard Time) * (observes South African Standard Time) * (observes South African Standard Time) * (observes Eastern European Time) * (observes South African Standard Time) See also * Egypt Standard Time, an equivalent time zone covering Egypt, also at UTC+02:00 * Kaliningrad Time, an equivalent time ...
