Mining In The Republic Of The Congo
Oil and gas dominate the extraction industries of the Republic of the Congo (), also referred to as Congo-Brazzaville. The petroleum industry accounted for 89% of the country’s exports in 2010. Among African crude oil producers in 2010, The Congo ranked seventh. Nearly all of the country's hydrocarbons were produced off-shore. The minerals sector is administered by the Department of Mines and Geology. Presently no major mining activities are underway, although there are some small-scale domestic operations. However, the country does have numerous large-scale undeveloped resources. The country has recently attracted a strong influx of international companies seeking to tap into the vast mineral wealth. As of 2012: *32 prospecting licenses granted to 28 companies *42 exploration licenses granted to 26 companies *7 mining licenses granted to companies Natural resources History Colonial During the colonial period, the Republic of the Congo saw small-scale mechanized mining ...

Mineral Extraction
Mining is the Resource extraction, extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agriculture, agricultural processes, or feasibly created Chemical synthesis, artificially in a laboratory or factory. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even fossil water, water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final mine reclamation, reclamation or restoration of the land after the mine is closed.

Sundance Resources
Sundance Resources Limited is an Australian mining company, based in Perth, Western Australia, whose main assets are iron ore leases in Cameroon near Mbalam, and across the border in the Republic of Congo. Following the loss of the Congo mining licence in 2020, Sundance Resources delisted from the Australian Securities Exchange and sued Congo to acquire $8.76 billion in compensation. To exploit these leases, a 500 km railway (or perhaps a slurry pipeline) is required to a new multi-user port at Lolabé on the Atlantic coast. However, the development of the project has been postponed due to the market conditions for ore. The company made headlines in June 2010 when all of the company's directors and some other officers were killed in an airplane crash in the Republic of Congo.Missing Aircraft Update Sundance ...

Gabon
Gabon ( ; ), officially the Gabonese Republic (), is a country on the Atlantic coast of Central Africa, on the equator, bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo to the east and south, and the Gulf of Guinea to the west. It has an area of and a population of million people. There are coastal plains, mountains (the Crystal Mountains (Africa), Cristal Mountains and the Chaillu Massif in the centre), and a savanna in the east. Libreville is the country's capital and largest city. Gabon's original inhabitants were the African Pygmies, Bambenga. In the 14th century, Bantu expansion, Bantu migrants also began settling in the area. The Kingdom of Orungu was established around 1700. France colonised the region in the late 19th century. Since its independence from France in 1960, Gabon has had four President of Gabon, presidents. In the 1990s, it introduced a multi-party system and a democratic constitution that aimed for a more tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moanda, Gabon
Moanda is one of the largest towns in Gabon, lying on the N3 road in Haut Ogooué. It is also one of the most important manganese mining towns in the world, under the auspices of the '' Compagnie minière de l'Ogooué'' (COMILOG), which began mining in 1957. Moanda has a population of around 39,298 inhabitants (2010 est.) and is the second largest city in the Haut Ogooué Region, after Franceville. It is also a border town, lying 100 km away from the border with the Republic of Congo. History Moanda was originally a village lying on the swampy banks of the Miosso River. The discovery and exploitation of manganese in the nearby Bangombe Plateau from 1953 led to the emergence of the city. In 1977 Moanda had an estimated 230 million tons of manganese, some one-fifth of the world's deposits. In 1959, the 75 km COMILOG Cableway to the railway at Mbinda in the Republic of Congo was constructed to export the manganese, but it was eventually closed in 1986 when the ...

Manganese
Manganese is a chemical element; it has Symbol (chemistry), symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. It 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 is commonly found in labo ...

Congo Basin
The Congo Basin () is the sedimentary basin of the Congo River. The Congo Basin is located in Central Africa, in a region known as west equatorial Africa. The Congo Basin region is sometimes known simply as the Congo. It contains some of the largest tropical rainforests in the world and is an important source of water used in agriculture and energy generation. The rainforest in the Congo Basin is the largest rainforest in Africa and second only to the Amazon rainforest in size, with 300 million hectares compared to the 800 million hectares in the Amazon. Because of its size and diversity the basin's forest is important for mitigating climate change in its role as a carbon sink. However, deforestation and degradation of the ecology by the impacts of climate change may increase stress on the forest ecosystem, in turn making the hydrology of the basin more variable. A 2012 study found that the variability in precipitation caused by climate change will negatively affect economic a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnallite
Carnallite (also carnalite) is an evaporite mineral, a hydrated potassium magnesium chloride with formula KCl.MgCl2·6(H2O). It is variably colored yellow to white, reddish, and sometimes colorless or blue. It is usually massive to fibrous with rare pseudohexagonal orthorhombic crystals. The mineral is deliquescent (absorbs moisture from the surrounding air) and specimens must be stored in an airtight container. Carnallite occurs with a sequence of potassium and magnesium evaporite minerals: sylvite, kainite, picromerite, polyhalite, and kieserite. Carnallite is an uncommon double chloride mineral that only forms under specific environmental conditions in an evaporating sea or sedimentary basin. It is mined for both potassium and magnesium and occurs in the evaporite deposits of Carlsbad, New Mexico; the Paradox Basin in Colorado and Utah; Stassfurt, Germany; the Perm Basin, Russia; and the Williston Basin in Saskatchewan, Canada. These deposits date from the Devonian through the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
