Mining Industry Of Guinea
The mining industry of Guinea was developed during colonial rule. The minerals extracted consisted of iron, gold, diamond, and bauxite. Guinea ranks first in the world in bauxite reserves and 6th in the extraction of high-grade bauxite, the aluminium ore. The mining industry and exports of mining products accounted for 17% of Guinea's gross domestic product (GDP) in 2010. Mining accounts for over 50% of its exports. The country accounts for 94% of Africa's mining production of bauxite. The large mineral reserve, which has mostly remained untapped, is of immense interest for international firms. In recent years, the mining industry in Guinea has suffered from controversy, specifically with respect to the iron ore mining industry and the block of mines in Northern Guinea. In 2019, the country was the world's 3rd largest producer of bauxite. History The mining tradition of Guinea is ancient and can be traced to a period before the Middle Ages, when gold and salt were trading com ...

Executive power is exercised by the government. Legislative power is vested in both the government and the National Assembly. Political history Conté era (1984–2008) A military dictatorship, led by then-Lt. Col. Lansana Conté and styling itself the Military Committee of National Recovery (CMRN), took control of Guinea in April 1984, shortly after the death of independent Guinea's first president, Sékou Touré. With Conté as president, the CMRN set about dismantling Touré's oppressive regime, abolishing the authoritarian constitution, dissolving the sole political party and its mass youth and women's organizations, and announcing the establishment of the Second Republic.

Fria
Fria is a town and Sub-prefecture in Lower Guinea, lying north of Conakry near the Amaria Dam on the Konkouré River. As of 2014 it had a population of 61,691 people. Overview There are some variations in the name of the town: Friguia, Kimbo or Kimbo-city. Fria is known for its local caves, the Grottes de Bogoro and the Grottes de Konkouré). The town's economy relies heavily upon bauxite mining and aluminum production. The town of Fria was built around a company called Kimbo-Fria, now ACG Fria (Aluminum Company of Guinea), Africa's first aluminum factory. ACG-Fria is the only operating alumina refinery in Guinea, producing 600,000 tonnes of alumina and 2.8 million tonnes of bauxite per year. Recently, the president of Guinea, Lansana Conte, signed an agreement with RUSAL privatizing the bauxite and aluminum complex in Fria run by the Alumina Company of Guinea. This will allow for eventual doubling of the company's capacity. The town is served by Fria Airport. Railwa ...

Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an e ...

Manganese
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese was first isolated in 1774. It is familiar in the laboratory in the form of the ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ...
