Mining In Benin
The mineral industry, which is limited to the production of cement, clay, gold, sand, and gravel, does not play a significant role in the Benin's economy.Omayra Bermúdez-Lugo"The Mineral Industry of Benin, Burkina Faso, and Sao Tome e Principe". ''2006 Minerals Yearbook''. U.S. Geological Survey (October 2007). ''This article incorporates text from this U.S. government source, which is in the public domain''. Cement was produced by Ciments du Benin S.A., Société des Ciments d’Onigbolo, and Société des Ciments du Benin. These companies had a combined cement production capacity of 1.43 million metric tons per year (Mt/yr). Gold was produced by artisanal miners from gold veins near the villages of Kwatena and Tchantangou, in the Atakora Mountains in northwestern Benin, and from alluvial sediments along the Perma River and its tributaries. Benin ceased petroleum production from its Seme oilfield in 1998; however, at least one company, Kosmos Energy LLC of the United States ...

Mineral
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or are organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct ...

Seismic
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. It also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, glacial, fluvial, oceanic, atmospheric, and artificial processes such as explosions. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of Earth motion as a function of time is called a seismogram. A seismologist is a scientist who does research in seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE), Aristotle (c. 340 BCE), and Zhan ...

Kosmos Energy
Kosmos Energy is an American upstream oil company founded and based in Dallas, Texas. While previously incorporated in Bermuda, Kosmos has reincorporated in Delaware. The company holds production and development operations offshore Ghana, Equatorial Guinea, and Gulf of Mexico, while holding a development project offshore Mauritania and Senegal, and exploration licenses offshore Namibia, São Tomé and Príncipe and Suriname. It was previously involved in exploration offshore Morocco and Western Sahara. It discovered the Jubilee oil field off the coast of Ghana and the cross-border Tortue gas field offshore Mauritania and Senegal. Kosmos was the focus of a documentary '' Big Men'' that followed the company as it worked to establish the Jubilee oil field in Ghana. History Kosmos Energy was established in 2003 by founding partners James C. Musselman, Brian F. Maxted, W. Greg Dunlevy, and Paul Dailly. Initial backing came from American private equity firms Warburg Pincus and The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Atakora Mountains
The Togo Mountains is a mountain range which stretches across the central region of the West African country of Togo and across the eastern and western borders of that country into Ghana and Benin. In Ghana, the range is also known as the Akwapim Hills, and in Benin it is also known as the Atakora Mountains . Part of the range is associated with the country of Niger, where the W National Park is found.W National Park of Niger. 2009 The African wild dog, ''Lycaon pictus'', was historically found in this region but may now be extirpated from this locale.C. Michael Hogan. 2009 Geography The Togo Mountains run across the central region of Togo, ranging from the southwest to the northeast. To the northeast, the mountain range extends into Benin where it is known as the Atakora Mountains, and to the southwest it extends into Ghana where it is known as the Akwapim Hills. The average elevation of these mountains is and the highest peak in Togo is Mount Agou, with a height of . It is in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artisanal
An artisan (from french: artisan, it, artigiano) is a skilled craft worker who makes or creates material objects partly or entirely by hand. These objects may be functional or strictly decorative, for example furniture, decorative art, sculpture, clothing, food items, household items and tools and mechanisms such as the handmade clockwork movement of a watchmaker. Artisans practice a craft and may through experience and aptitude reach the expressive levels of an artist. History The adjective "artisanal" is often used in describing hand-processing in contrast to an industrial process, such as in the phrase ''artisanal mining''. Thus, "artisanal" is sometimes used in marketing and advertising as a buzz word to describe or imply some relation with the crafting of handmade food products, such as bread, beverages or cheese. Many of these have traditionally been handmade, rural or pastoral goods but are also now commonly made on a larger scale with automated mechanization i ...

Cement
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource. Cements used in construction are usually inorganic, often lime or calcium silicate based, which can be characterized as hydraulic or the less common non-hydraulic, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable in wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
