Trepča Mines
The Trepča Mines ( al, Miniera e Trepçës, sr, Рудник Трепча / ''Rudnik Trepča'') is a large industrial complex in Kosovo, located northeast of Mitrovica. The mine is located on the southern slopes of the Kopaonik mountain, between the peaks of Crni Vrh () and Majdan , and it is Europe's largest lead-zinc and silver ore mine. With up to 23,000 employees, Trepča was once one of the biggest companies in Yugoslavia. In the 1930s, the Selection Trust gained the rights to exploit the Stari Trg mine close to Mitrovica. After World War II, under socialist management, the company further expanded. Overview The enterprise known as Trepča was a conglomerate of 40 mines and factories, located mostly in Kosovo but also in locations in Montenegro. But the heart of its operations, and the source of most of its raw material, is the vast mining complex to the east of Mitrovica in the north of Kosovo, famous since Roman times. However, with the closure of several mines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitrovica, Kosovo
Mitrovica ( sq-definite, Mitrovicë; sr-cyrl, Митровица) or Kosovska Mitrovica ( sr-cyrl, Косовска Митровица) is a city and municipality located in Kosovo. Settled on the banks of Ibar and Sitnica rivers, the city is the administrative center of the District of Mitrovica. In 2013, following the North Kosovo crisis, the Serb-majority municipality of North Mitrovica was created, dividing the city in two administrative units. According to the 2011 Census, in Mitrovica live 97,686 inhabitants, 85,360 of which in the southern municipality and 12,326 in North Mitrovica. Name The name of Mitrovica derives from the name ''Demetrius''. It was most probably named after the 8th century Byzantine church ''St. Demetrius'' which was built near Zvečan Fortress, just above the modern Mitrovica, in honor of Saint Demetrius of Thessaloniki. The city was called ''D(i)mitrovica'' until it fell under the Ottoman rule. In 1660, the Ottoman explorer Evliya Çel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stefan Uroš I
Stefan Uroš I ( sr-cyr, Стефан Урош I; 1223 – May 1, 1277), known as Uroš the Great (Урош Велики) was the King of Serbia from 1243 to 1276, succeeding his brother Stefan Vladislav. He was one of the most important rulers in Serbian history. Early life Stefan Uroš was the youngest son of Stefan the First-Crowned and Anna, the granddaughter of Enrico Dandolo, Doge of Venice. He had two older half-brothers, on his father's side, kings Stefan Radoslav and Stefan Vladislav. Scholars have argued that Bulgarian influence had been strong and unpopular, causing opposition that led to Vladislav's deposition after the death of Asen. The revolting nobility had chosen Uroš as their candidate for king; from 1242 to spring 1243, a war for the throne was fought, which ended with Vladislav being forced to give up the crown in favour of Uroš. It seems that Uroš captured Vladislav. The main resistance against Uroš was led by Vladislav's wife, Beloslava. The hostil ...

Byzantine Empire
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient Rome a ...

Dardani
The Dardani (; grc, Δαρδάνιοι, Δάρδανοι; la, Dardani) or Dardanians were a Paleo-Balkan people, who lived in a region that was named Dardania after their settlement there. They were among the oldest Balkan peoples, and their society was very complex. The Dardani were the most stable and conservative ethnic element among the peoples of the central Balkans, retaining for several centuries an enduring presence in the region. Most ancient sources classify Dardanians as Illyrians. Strabo and Appian explicitly referred to them as Illyrians. Strabo, in particular – also mentioning Galabri and Thunatae as Dardanian tribes – describes the Dardani as one of the three strongest Illyrian peoples, the other two being the Ardiaei and Autariatae. There were Thracian names in the eastern strip of Dardania but Illyrian names dominated the rest The Kingdom of Dardania was attested since the 4th century BC in ancient sources reporting the wars the Dardanians waged ag ...

Municipium Dardanorum
Municipium Dardanorum or Municipium DardanicumThe Illyrians by J. J. Wilkes, 1992, , p. 258,"In the south the new city named municipium Dardanicum, was another 'mining town' connected with the local workings (Metalla Dardanica)." was a Roman mining town whose life lasted from the 2nd to the 4th century AD, that was connected with the workings of (''Metalla Dardanica''). Its remains are situated in the northern part of Kosovo, located approximately 27 kilometres north of Mitrovica, about 65 km northeast of Ulpiana in the Municipality of Leposavic, localized in the village of Sočanica in the province of Moesia Superior, later the Roman province of Dardania. Location The site has excellent geography, located between the Ibar and Sočanica rivers flowing one side, and surrounded by the Rogozna and Kopaonik mountains on the other side. The surrounding area used to be rich in precious metals (gold and silver), and because of these natural resources, the occupancy grew ...

Dross
Dross is a mass of solid impurities floating on a molten metal or dispersed in the metal, such as in wrought iron. It forms on the surface of low- melting-point metals such as tin, lead, zinc or aluminium or alloys by oxidation of the metal. For higher melting point metals and alloys such as steel and silver, oxidized impurities melt and float making them easy to pour off. With wrought iron, hammering and later rolling remove some dross. With tin and lead the dross can be removed by adding sodium hydroxide pellets, which dissolve the oxides and form a slag. If floating, dross can also be skimmed off. Dross, as a solid, is distinguished from slag, which is a liquid. Dross product is not entirely waste material; for example, aluminium dross can be recycled and is also used in secondary steelmaking for slag deoxidation. Etymology and usage The term ''dross'' derives from the Old English word ''dros'', meaning the scum produced when smelting metals (extracting them from their ores ...

Roman Empire
The Roman Empire ( la, Imperium Romanum ; grc-gre, Βασιλεία τῶν Ῥωμαίων, Basileía tôn Rhōmaíōn) was the post-Roman Republic, Republican period of ancient Rome. As a polity, it included large territorial holdings around the Mediterranean Sea in Europe, North Africa, and Western Asia, and was ruled by Roman emperor, emperors. From the Constitutional reforms of Augustus, accession of Caesar Augustus as the first Roman emperor to the Crisis of the Third Century, military anarchy of the 3rd century, it was a Principate with Roman Italy, Italia as the metropole of Roman province, its provinces and the Rome, city of Rome as its sole capital. The Empire was later ruled by dominate, multiple emperors who shared control over the Western Roman Empire and the Byzantine Empire#Early history, Eastern Roman Empire. The city of Rome remained the nominal capital of both parts until AD 476 when the imperial insignia were sent to Constantinople following the capture of ...

Silver
Silver is a chemical element with the symbol Ag (from the Latin ', derived from the Proto-Indo-European ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures.

Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. I ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
