Kediet Ej Jill
Kediet ej Jill () is a mountain in Tiris Zemmour, Mauritania, with the city of Zouérat on its east and Fderick at west. At tall, Kediet ej Jill includes the highest peak in Mauritania. The mountain and its surrounding area are rich in iron deposits, thought to have been mined here since the 11th century and commercially exploited since 1952. The current mines are connected to Nouadhibou on the Atlantic coast by a 700-km long railway. The mountain appears bluish because of the high concentration of magnetite Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe2+Fe3+2O4.

Mauritania
Mauritania (; ar, موريتانيا, ', french: Mauritanie; Berber: ''Agawej'' or ''Cengit''; Pulaar: ''Moritani''; Wolof: ''Gànnaar''; Soninke:), officially the Islamic Republic of Mauritania ( ar, الجمهورية الإسلامية الموريتانية), is a sovereign country in West Africa. It is bordered by the Atlantic Ocean to the west, Western Sahara to the north and northwest, Algeria to the northeast, Mali to the east and southeast, and Senegal to the southwest. Mauritania is the 11th-largest country in Africa and the 28th-largest in the world, and 90% of its territory is situated in the Sahara. Most of its population of 4.4 million lives in the temperate south of the country, with roughly one-third concentrated in the capital and largest city, Nouakchott, located on the Atlantic coast. The country's name derives from the ancient Berber kingdom of Mauretania, located in North Africa within the ancient Maghreb. Berbers occupied what is now Mauritania ...

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Zouérat
Zouérat ( ar, الزويرات) is the largest town in northern Mauritania and the capital of Tiris Zemmour region, with an approximate population of 44,649 (2013). It lies at the eastern end of the Mauritania Railway to Nouadhibou. History The town developed from its importance to iron ore mining. It is surrounded by the hematite mines of Fderîck, Tazadit and Rouessa. The town houses the regional administration and military for Tiris Zemmour. Most of the town's population are employed directly and indirectly in the mining industry. A sizeable number of foreign workers from other African countries live in the town. Amenities include a medical clinic, social club, pool, school and shop. Since 2006, a shanty town has grown around the town. In response authorities have begun construction of a wall, nicknamed locally as the "''mur de la honte''" (wall of shame), to separate the two areas. Mining Mining at the mountain was first recorded from the Kediet ej Jill in the 11th c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nouadhibou
Nouadhibou (; ar, نواذيبو, Nwādībū, Berber: Nwadibu, formerly in French: ) is the second largest city in Mauritania and serves as a major commercial centre. The city itself has about 118,000 inhabitants expanding to over 140,000 in the larger metropolitan area. It is situated on a 65-kilometre peninsula or headland called Ras Nouadhibou (Berber: ''Ighef Nwadibu''), , or , of which the western side has the Western Saharan city of La Güera. Nouadhibou is consequently located merely a couple of kilometres from the border between Mauritania and Western Sahara. Its current mayor is Elghassem Ould Bellali, who was installed on 15 October 2018. Overview The city consists of four major areas: the city centre, including the airport; Numerowatt to the north; Cansado, the main residential area, to the south; and a dormitory town for the workers of the harbour facilities which are located a few kilometers south of the city, near the tip of the Ras Nouadhibou peninsula, at Por ...

Mauritania Railway
The Mauritania Railway is the national railway of Mauritania. Construction of the line began in 1960, with it opening in 1963. It consists of a single, railway line linking the iron mining centre of Zouérat with the port of Nouadhibou, via Fderik and Choum. The state agency ''Société Nationale Industrielle et Minière'' (National Mining and Industrial Company, SNIM) controls the railway line. Since the closure of the Choum Tunnel, a section of the railway cuts through the Polisario Front- controlled part of the Western Sahara (). History The line was a success and provided a major portion of Mauritania's GDP; as a result the line was nationalised in 1974. Following Mauritania's annexation of southern Western Sahara in 1976, the line came under constant attack by Polisario militia, effectively putting the line out of use and thereby crippling Mauritania's economy. This played a major role in prompting the army to overthrow Mauritanian president Moktar Ould Daddah in 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetite
Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe2+Fe3+2O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and leaves a black streak. Small grains of magnetite are very common in igneous and metamorphic rocks. The chemical IUPAC name is iron(II,III) oxide and the common chemical name is ''ferrous-ferric oxide''. Properties In addition to igneous rocks, magnetite also occurs in sedimentary rocks, including banded iron formations and in lake and marine sediments ...

Landforms Of Mauritania
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
