Compagnie Minière De L'Ogooué
The Compagnie minière de l'Ogooué, or COMILOG, is a manganese mining and processing company based in Moanda, Gabon. It is a subsidiary of the French metallurgical group Eramet. The company is the world's second largest producer of manganese ore. At first the ore was carried by a cableway to the border with the Republic of the Congo, then by rail to the sea at Pointe-Noire. In the 1980s a railway was built to carry the ore through Gabon to the sea near Libreville. Ore deposits Manganese was first reported in the Franceville region in 1895. Further discoveries were made in 1934, 1944 and 1945. Systematic exploration began in 1951. In 1951 a joint mission of the Bureau Minier de la France d'Outre-Mer and U.S. Steel found a large deposit estimated at over 100 million tonnes of marketable ore. The ore is high quality with a manganese content of 45–50%. The deposits are found in five plateaus around Moanda in the Haut-Ogooué Province and were formed by supergene enrichment of Preca ...

Moanda
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 Tra ...

Ramsdellite
Ramsdellite (Mn4+O2) is an orthorhombic manganese dioxide mineral. It is relatively uncommon, and is usually found in deposits containing other manganese oxide crystals. Name Ramsdellite is named after the American mineralogist, Lewis Stephen Ramsdell (1895–1975). Ramsdell spent almost all his career at the University of Michigan as a professional mineralogist. Ramsdellite was one of the new phases he first recognized in the "black manganese oxide" minerals. It was later named in his honour by Michael Fleischer and W. E. Richmond, who fully described the mineral in 1943. The mineral is also called Groutellite. Chemistry and crystallography The chemical formula for Ramsdellite is MnO2. The empirical formula is Mn4+O2. Ramsdellite has the same chemistry as the more common pyrolusite, but is orthorhombic where pyrolusite is tetragonal. Ramsdellite belongs to the Orthorhombic crystal system and Dipyramidal crystal class. Properties: Classification The Dana classification is 4. ...

Trans-Gabon Railway
The Trans-Gabon Railway (french: Transgabonais) is the only railway in Gabon. It runs east from Owendo port station in Libreville to Franceville via numerous stations, the main ones being Ndjolé, Lopé, Booué, Lastoursville and Moanda. History A railway was first planned in 1885. Investigations into the line were conducted in 1968, funding was agreed in 1973, and construction began the following year. The first section, from Owendo to Ndjolé, opened in 1978, with the remaining sections opening in stages until December 1986. Costs were well over budget and almost bankrupted the country. The Trans-Gabon Railway is overall adjacent the Ogooue River until Ndjolé. Most important constructions are the Juckville Tunnel, the viaduct over the Abanga swamp, and the bridge over the confluence between the Ogooue and the Ivindo Rivers. The line to Franceville was completed in 1987. Originally intended to reach Makokou and carry iron ore, its route was changed for politica ...

COMILOG Cableway
The COMILOG Cableway was one of the longest cableways in the world, until its closure in 1986. The ropeway conveyor ran for 76 km from Moanda in the Haut-Ogooué Province of south eastern Gabon to Mbinda in the Republic of Congo. In 1954, the Compagnie Minière de l'Ogooué (COMILOG), a French-American company formed the previous year, decided to begin mining manganese in the Gabonese town of Moanda. The town lay deep in the rainforest, and export of the metal was a problem. The nearest reliable transport route was the Congo-Ocean Railway, but this lay more than 250km away, across difficult terrain. George Perrineau was charged with constructing a transport link between the two. It was decided to construct a cableway from Moanda to Mbinda, and then branch of the Congo-Ocean Railway to Mont Bello, from which the existing railway would link to the port of Pointe-Noire.Ya SanzaDossiers spéciaux: COMILOG pecial Dossier: COMILOG/ref> The conveyor was routed via the small t ...

Henri Lafond
Henri Lafond (20 August 1894 – 6 March 1963) was a French mining engineer and businessman who headed or sat on the board of numerous large companies and was involved in various industrial associations and committees both before and after World War II (1939–45). During the war he held a senior position in the Vichy government's Ministry of Industrial Production from 1940 to 1942. He was assassinated in March 1963, apparently by an OAS member due to his refusal to support the movement to oppose Algerian independence. Early years (1894–1939) Henri Lafond was born on 20 August 1894 in Thaumiers, Cher. His parents were Joseph Lafond, a tobacconist, and Juliette Alexandrine Guénard. His father was the son of a laborer. Henri Lafond studied at the Thaumiers commune school, then at the Bourges ''lycée''. He entered the École Polytechnique in 1914. He was described as having brown hair, vertical brow, straight nose, chestnut eyes, oval face, height . Lafond was awarded the Croix d ...

Port
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhou ...

Congo–Ocean Railway
The Congo–Ocean Railway (COR; french: Chemin de fer Congo-Océan, ) links the Atlantic port of Pointe-Noire (now in the Republic of Congo) with Brazzaville, a distance of . It bypasses the rapids on the lower Congo River; from Brazzaville, river boats are able to ascend the Congo River and its major tributaries, including the Oubangui River to Bangui. the railroad was regularly operating freight and passenger services along the length of the line despite the poor state of the track. A luxury passenger train, ''La Gazelle'', using Korean-manufactured passenger cars, was introduced in 2012; as of 2014 it operated between Pointe-Noire and Brazzaville every other day, and was scheduled to take 14–16 hours to complete the journey. History Under French colonial administration, in 1921 they contracted Société de Construction des Batignolles to construct the railway using forced labour, recruited from what is now southern Chad and the Central African Republic.

Cableway
Cable transport is a broad class of transport modes that have cables. They transport passengers and goods, often in vehicles called cable cars. The cable may be driven or passive, and items may be moved by pulling, sliding, sailing, or by drives within the object being moved on cableways. The use of pulleys and balancing of loads moving up and down are common elements of cable transport. They are often used in mountainous areas where cable haulage can overcome large differences in elevation. Common modes of cable transport Aerial transport Forms of cable transport in which one or more cables are strung between supports of various forms and cars are suspended from thes cables. * Aerial tramway * Chairlift * Funitel * Gondola lift * Ski lift * Zip line Cable railways Forms of cable transport where cars on rails are hauled by cables. The rails are usually steeply inclined and usually at ground level. * Cable car * Funicular Other Other forms of cable-hauled transpo ...
