Ashanti Mine
The Obuasi Gold Mine is an underground gold mine situated near Obuasi, in the Ashanti Region of Ghana. It was at one time one of the world's ten largest gold mines. The mine is in Obuasi Municipal District, southwest of the regional capital Kumasi. In 2008, AngloGold Ashanti's Ashantiland operations, consisting of Obuasi and the Iduapriem Gold Mine, contributed 11% to the company's annual production. At its temporary closure in 2014 Obuasi had past gold production plus current resource of 62 million troy ounces. History There is a long history of mining in the area, with mining from the Ashanti region providing the gold for which the Gold Coast got its name. Large scale commercial and industrial mining began at Obuasi in 1897 with the formation of Ashanti Goldfields Corporation. ayiajavon.com, accessed: 9 August 2010 ...

Gold Coast (region)
The Gold Coast was the name for a region on the Gulf of Guinea in West Africa that was rich in gold, petroleum, sweet crude oil and natural gas. This former region is now known as the country Ghana. Etymology and position The Gold Coast, Slave Coast, Pepper Coast (or Grain Coast) and Ivory Coast were named after the main export resources found there, respectively. Early uses of the term ''Gold Coast'' refer strictly to the coast and not the interior. It was not until the 19th century that the term came to refer to areas that are far from the coast. The Gold Coast was to the east of the Ivory Coast and to the west of the Slave Coast. Territorial entities Gold Coast region territorial entities were: * Portuguese Gold Coast (Portuguese, 1482–1642) * Dutch Gold Coast (Dutch, 1598–1872) * Swedish Gold Coast (Swedes, 1650–1658; 1660–1663) * Couronian Gold Coast (Duchy of Courland and Semigallia, 1651–1661) * Danish Gold Coast ( Denmark-Norway, 1658–1850) * Bran ...

Surface Mines In Ghana
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called ''surface'', sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfac ...

Gold Mines In Ghana
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is i ...

African, Caribbean And Pacific Group Of States
The Organisation of African, Caribbean and Pacific States (OACPS) is a group of countries in Africa, the Caribbean, and the Pacific that was created by the Georgetown Agreement in 1975. Formerly known as African, Caribbean and Pacific Group of States (ACP), the organisation's main objectives are sustainable development and poverty reduction within its member states, as well as their greater integration into the world's economy. All of the member states, except Cuba, are signatories to the Cotonou Agreement with the European Union. The Cotonou Agreement (signed in Cotonou, Benin, in June 2000) is the successor to the Lomé Conventions. One of the major differences from the Lomé Convention is that the partnership is extended to new actors such as civil society, private sector, trade unions and local authorities. These will be involved in consultations and planning of national development strategies, provided with access to financial resources and involved in the implementati ...

Birimian
The Birimian rocks are major sources of gold and diamonds that extend through Ghana, Côte d'Ivoire, Guinea, Mali and Burkina Faso. They are named after the Birim River, one of the main tributaries of the Pra River in Ghana and the country's most important diamond-producing area. Ghana and Mali are the second and third largest producers of gold in Africa, respectively. The Birimian terranes in the southern part of the West African craton are a mix of metamorphosed volcanic, sedimentary, and plutonic rocks and low-grade metavolcanics and metasediments. Almost half of the terranes consist of alkaline granites. The rocks formed over a period of about 50 million years between 2.200 Ga and 2.100 Ga years ago. Location The Birimian rocks stretch across the countries to the north of the Gulf of Guinea, forming parallel belts that generally trend northeasterly and are wide and about apart. They consist of interlayered sedimentary and volcanic flow rocks metamorphosed to low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Ghana
The geology of Ghana is primarily very ancient crystalline basement rock, volcanic belts and sedimentary basins, affected by periods of igneous activity and two major orogeny mountain building events. Aside from modern sediments and some rocks formed within the past 541 million years of the Phanerozoic Eon, along the coast, many of the rocks in Ghana formed close to one billion years ago or older leading to five different types of gold deposit formation, which gave the region its former name Gold Coast (region), Gold Coast. Stratigraphy, Tectonics & Geologic History Ancient rocks from the Paleoproterozoic, Neoproterozoic and perhaps early Paleozoic cover almost all of Ghana, except near the coast where Paleozoic, Mesozoic and Cenozoic rocks are common. Main Precambrian rock units include the metamorphosed and fold (geology), folded Dahomeyan, Birimian, Tarkwaian system (geology), System, Togo series (geology), Series, and the Buem formation (geology), Formation.

United States Dollar
The United States dollar ( symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Care And Maintenance
Care and maintenance is a term used in the mining industry to describe processes and conditions on a closed minesite where there is potential to recommence operations at a later date. During a care and maintenance phase, production is stopped but the site is managed to ensure it remains in a safe and stable condition. Causes The mine might be considered to be temporarily unviable, due to current economic conditions or unfavourable resource prices, which are expected to improve at a later date. Declining ore grades at some mines can also be a reason for care and maintenance announcements. In some cases controlling interest companies decide not to further funding for subsidiary operations. During closure While the mine is closed, a care and maintenance program will manage environmental risks associated with tailings dumps, hazardous materials and open and underground pits. Care of idle plant and machinery will also be included in the program. Public health and safety consideratio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
