Mining in Gabon

Last updated

Gabon was the richest of the former French Equatorial African colonies in known mineral deposits. In addition to oil, which accounted for 80% of the country's exports in 2004, Gabon is a world leader in manganese. Potash, uranium, niobium, iron ore, lead, zinc, diamonds, marble, and phosphate have also been discovered, and several deposits are being exploited commercially. Ownership of all mineral rights is vested in the government, which has increased its share of the profits accruing to foreign companies under development contracts.

Gabon country in Africa

Gabon, officially the Gabonese Republic, is a country on the west coast of Central Africa. Located on the equator, Gabon is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of nearly 270,000 square kilometres (100,000 sq mi) and its population is estimated at 2.1 million people. Its capital and largest city is Libreville.

Manganese Chemical element with atomic number 25

Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is 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.

Potash salt mixtures that contain potassium in water-soluble form, mainly: halite, sylvite, carnallite, kieserite

Potash includes various mined and manufactured salts that contain potassium in water-soluble form. The name derives from pot ash, which refers to plant ashes soaked in water in a pot, the primary means of manufacturing the product before the industrial era. The word potassium is derived from potash.

Manganese

The high-grade manganese deposits at Moanda, near Franceville, are among the world's richest. Reserves were estimated at 250 million tons with a metal content of 48%–52%. Production had been limited to a ceiling of 2.8 million tons a year, corresponding closely to the capacity of the cableway—at 76 km, Africa's longest overhead cable—used to transport the mineral to the Congo border, from where it was carried by rail to the port of Pointe Noire. The newer Trans-Gabon Railway provided an alternate export outlet through the Gabonese port of Owendo, and the cableway was made redundant. Use of the railroad has cut shipping costs by $20 million per year. Before nationalization, Manganese was exploited by the Mining Co. of L’Ougoué (Comilog, an international consortium), which ranked among the world's lowest-cost producers. In 2004, an estimated 2.4 million metric tons of metallurgical-grade ore were extracted, up from 1.95 million metric tons in 2003. Annual production capacity at the Moanda Mine was 2.5 million tons, which amounts to around $5,442,000,000 a year, with reserves estimated to last 100 years.

Moanda Place in Haut-Ogooué Province, 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 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.

Franceville Place in Haut-Ogooué Province, Gabon

Franceville is one of the four largest cities in Gabon, with a population of around 110,568 people. It lies on the River Mpassa and at the end of the Trans-Gabon Railway and the N3 road. It grew from a village named Masuku when Pierre Savorgnan de Brazza chose it to resettle former slaves and renamed it "Francheville" in 1880. The city later came to be called Franceville.

Trans-Gabon Railway railway in Gabon

The Trans-Gabon Railway is the only railway in Gabon. It runs 670 km east from Owendo port station in Libreville to Franceville via numerous stations, the main ones being Ndjolé, Lopé, Booué, Lastoursville and Moanda.

In 2012, BHP Billiton were developing a second manganese deposit. [1]

Cement

Gabon also produced an estimated 350,000 metric tons each of clinker and hydraulic cement in 2004. Also in that year an estimated 500 carats (100 g) of diamonds (gem and industrial) were produced, along with 70 kg of gold.

Iron

The Mékambo and Belinga iron fields in the northeastern corner of Gabon are ranked among the world's richest. Reserves are estimated as high as 1 billion tons of ore of 60%–65% iron content, and production could reach 20 million tons a year. Although iron was discovered there in 1895, it was not until 1955 that a full-scale commercial license was issued. Exploitation still awaited the establishment of a 225 km extension of the Trans-Gabon Railroad from Booué to Belinga; construction has been considered unprofitable, because of unfavorable market conditions.

Mékambo Place in Ogooué-Ivindo Province, Gabon

Mékambo is a small town in north-eastern Gabon on the banks of the Zadié river. It is located in the Ogooué-Ivindo province of Gabon and is the seat of the Zadié Department. It has received international press for recent outbreaks of Ebola hemorrhagic fever in 1994 and 1997.

Belinga is a location in Gabon with as yet unexploited iron ore deposits. These ore deposits extend into neighbouring Cameroon and Congo.

Booué Town in Ogooué-Ivindo Province, Gabon

Booué is a small town in central Gabon. It is situated in Lopé Department, southwest side of the Ogooué-Ivindo Province. The town lies just 6.6 miles to the south of the Equator and is the province's only Department capital in the Southern Hemisphere.

Other minerals

The potential for new developments in niobium, gold, manganese, and possibly phosphate suggests a continued role for mining in the economy. The lack of adequate infrastructure inhibits new grassroots exploration and remains a major constraint on development of the well-defined iron ore deposit at Bélinga.

Economy of Gabon economy of the country

The economy of Gabon is characterized by strong links with France, large foreign investments, dependence on skilled foreign labor, and decline of agriculture. Gabon enjoys a per capita income four times that of most nations of sub-Saharan Africa, its reliance on resource extraction industry releasing much of the population from extreme poverty.

Modes of transport in Gabon include rail, road, water, and air. The one rail link, the Trans-Gabon Railway, connects the port of Owendo with the inland town of Franceville. Most but not all of the country is connected to the road network, much of which is unpaved, and which centres on seven "national routes" identified as N1 to N7. The largest seaports are Port-Gentil and the newer Owendo, and 1,600 km of inland waterways are navigable. There are three international airports, eight other paved airports, and over 40 with unpaved runways. Nearly 300 km of pipelines carry petroleum products, mainly crude oil.

Iron ore ore rich in iron or the element Fe

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe
3O
4, 72.4% Fe), hematite (Fe
2O
3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe).
