Ural Region
Ural () is a geographical region located around the Ural Mountains, between the East European and West Siberian plains. It is considered a part of the Eurasian Steppe, extending approximately from the North to the South; from the Arctic Ocean to the end of the Ural River near Orsk city. The border between Europe and Asia runs along the Eastern side of the Ural Mountains. Ural mostly lies within Russia but also includes a small part of Northwestern Kazakhstan. This is historical, not an official entity, with borders overlapping its Western Volga and Eastern Siberia neighboring regions. At some point in the past, parts of the currently existing Ural region were considered a gateway to Siberia, or even Siberia itself, and were combined with the Volga administrative the divisions. Today, there are two official namesake entities: the Ural Federal District and the Ural economic region. While the latter follows the historical borders, the former is a political product; the District ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bauxite
Bauxite () is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (), boehmite (γ-AlO(OH)), and diaspore (α-AlO(OH)), Mixture, mixed with the two iron oxides goethite (FeO(OH)) and haematite (), the aluminium Clay minerals, clay mineral kaolinite () and small amounts of anatase () and ilmenite ( or ). Bauxite appears dull in Lustre (mineralogy), luster and is reddish-brown, white, or tan. In 1821, the French people, French geologist Pierre Berthier discovered bauxite near the village of Les Baux-de-Provence, Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished Laterite, lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and ...

Chelyabinsk Oblast
Chelyabinsk Oblast; , is a federal subjects of Russia, federal subject (an oblast) of Russia in the Ural Mountains region, on the border of Europe and Asia. Its administrative center is the types of inhabited localities in Russia, city of Chelyabinsk. History During the Middle Ages, Bashkirs, Bashkir tribes inhabited the Southern Ural (region), Urals; they formed part of the Golden Horde, Nogai Horde, and smaller Bashkir unions. The Tsardom of Russia Russian conquest of Siberia, incorporated the area in the late 16th century. However, Russian colonization of the region only began in the 18th century, with the establishment of a system of fortresses and trade posts on the then-Russian border by the in 1734. Many cities of Chelyabinsk Oblast, including the city of Chelyabinsk itself, trace their history back to those forts.

Magnetite
Magnetite is a mineral and one of the main iron ores, with the chemical formula . It is one of the iron oxide, oxides of iron, and is ferrimagnetism, ferrimagnetic; it is attracted to a magnet and can be magnetization, 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 scale of mineral hardness, Mohs hardness of 5–6 and leaves a black streak (mineralogy), streak. Small grains of magnetite are very common in igneous rocks, 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 als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromite
Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of Iron, FeChromium, Cr2Oxygen, O4. It is an oxide mineral belonging to the spinel group. The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (Magnesium, MgChromium, Cr2Oxygen, O4). Substitution of the element aluminium can also occur, leading to hercynite (Iron, FeAluminum, Al2Oxygen, O4). Chromite today is mined particularly to make stainless steel through the production of ferrochrome (Iron, FeChromium, Cr), which is an iron-chromium alloy. Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and India. Chromite is iron-black in color with a metallic Lustre (mineralogy), luster, a dark brown Streak (mineralogy), streak and a hardness on the Mohs scale of mineral hardness, Mohs scale of 5.5.

Chalcopyrite
Chalcopyrite ( ) is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS2 and crystallizes in the tetragonal system. It has a brassy to golden yellow color and a Mohs scale, hardness of 3.5 to 4 on the Mohs scale. Its Streak (mineralogy), streak is diagnostic as green-tinged black. On exposure to air, chalcopyrite tarnishes to a variety of oxides, hydroxides, and sulfates. Associated copper minerals include the sulfides bornite (Cu5FeS4), chalcocite (Cu2S), covellite (CuS), digenite (Cu9S5); carbonates such as malachite and azurite, and rarely oxides such as cuprite (Cu2O). It is rarely found in association with native copper. Chalcopyrite is a conductor of electricity. Copper can be extracted from chalcopyrite ore using various methods. The two predominant methods are pyrometallurgy and hydrometallurgy, the former being the most commercially viable. Etymology The name chalcopyrite comes from the Greek words , which means cop ...
