Berggeschrey
Berggeschrey or Berggeschrei ("mining clamour") was a German term for the rapid spread of news on the discovery of rich ore deposits that led to the rapid establishment of a mining region, as in the silver rush in the early days of silver ore mining in the Ore Mountains. It is similar in some respects to the gold rush in North America. First Berggeschrey Even as the first settlements were established there were small finds tin, iron and copper. But when, in 1168, rich silver finds were discovered in the area of Freiberg, it precipitated the ''First Berggeschrey''. Upon hearing the news of rich silver deposits miners, traders, charcoal burners and vagabonds quickly poured into this, at that time, inhospitable area. ''"Where a man wants to look for ore, he is allowed to do so with rights"'' the Margrave of Meissen, owner of the rights to use the mountain (mining rights), had asserted to the settlers flooding into the area. In order to settle the miners, who mostly came from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Rush
A silver rush is the silver-mining equivalent of a gold rush, where the discovery of silver-bearing ore sparks a mass migration of individuals seeking wealth in the new mining region. Notable silver rushes have taken place in Mexico, Chile, the United States (Colorado, Nevada, California, Utah), and Canada ( Cobalt, Ontario, and the Kootenay district of British Columbia). Several famous tourist towns owe their existence to silver rushes. History Historically there were other "silver rushes", such as on the Attic peninsula near Athens, Greece, thousands of years ago. The silver mines of Laurion became famous for their exploitation and helped fund the new state of Athens. The term is also widely applied to the New World. Despite the larger-than-life image of the gold rush, the history of towns and industry in the North American West revolves much more around silver. This is partly because of the other minerals usually found with it – lead, tin, copper – and the more complic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freiberg (Saxony)
Freiberg is a university and former mining town in Saxony, Germany. It is a so-called ''Große Kreisstadt'' (large county town) and the administrative centre of Mittelsachsen district. Its historic town centre has been placed under heritage conservation and is a part of the UNESCO World Heritage Site known as the Ore Mountain Mining Region, due to its exceptional testimony to the development of mining techniques across many centuries. Until 1969, the town was dominated for around 800 years by the mining and smelting industries. In recent decades it has restructured into a high technology site in the fields of semiconductor manufacture and solar technology, part of Silicon Saxony. It is home of the oldest university of mining and metallurgy in the world – the Freiberg University of Mining and Technology. Geography Location The town lies on the northern declivity of the Ore Mountains, with the majority of the borough west of the Eastern or Freiberger Mulde river. Part ...

Schreckenberg
The Schreckenberg is a mountain near Frohnau in the county of Erzgebirgskreis in the central Ore Mountains of Germany. It is . It is located one kilometre northwest of the town of Annaberg-Buchholz in the borough of Frohnau. History The mountain is primarily of historical importance, since it is where Annaberg's silver ore mining began. On 28 October 1491, Caspar Nietzel came across a vein of silver ore not far from the Frohnau Upper Mill. As a result, in 1496, on the opposite bank of the river Sehma, the new town of Neustadt am Schreckenberg grew up, which soon received the name Sankt Annaberg ("Saint Anna's Mountain"). In 1498, Annaberg received the right to mint coins from the Wettins. The Annaberg Mint was set up in or next to the upper mill and for a short time minted the coin known as the '' Schreckenberger'', a widespread means of payment in the Holy Roman Empire. The saying ''You're a rich Annaberger, you've got a bag full of Schreckenbergers'' probably dates to this ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III-V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in rats, ham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miner
A miner is a person who extracts ore, coal, chalk, clay, or other minerals from the earth through mining. There are two senses in which the term is used. In its narrowest sense, a miner is someone who works at the rock face; cutting, blasting, or otherwise working and removing the rock. In a broader sense, a "miner" is anyone working within a mine, not just a worker at the rock face. Mining is one of the most dangerous trades in the world. In some countries, miners lack social guarantees and in case of injury may be left to cope without assistance. In regions with a long mining tradition, many communities have developed cultural traditions and aspects specific to the various regions, in the forms of particular equipment, symbolism, music, and the like. Roles Different functions of the individual miner. Many of the roles are specific to a type of mining, such as coal mining. Roles considered to be "miners" in the narrower sense have included: *Hewer (also known as "cake" or "pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johanngeorgenstadt
Johanngeorgenstadt () is a mining town in Saxony’s Ore Mountains, 17 km south of Aue, and 27 km northwest of Karlovy Vary. It lies in the district of Erzgebirgskreis, on the border with the Czech Republic, is a state-recognized health resort (''Erholungsort''), and calls itself ''Stadt des Schwibbogens'' (“Schwibbogen Town”). Its population decline since the 1950s has been extremely severe falling from 45,000 residents in 1953 to only about one tenth of that now. Geography Location The town stretches predominantly from the eastern ridge of the almost 900-m-high Fastenberg to where the Breitenbach, which forms part of the border with the Czech Republic, empties into the river Schwarzwasser.

Wismut (company)
SAG/SDAG Wismut was a uranium mining company in East Germany during the time of the Cold War. It produced a total of 230,400 tonnes of uranium between 1947 and 1990 and made East Germany the fourth largest producer of uranium ore in the world at the time. It was the largest single producer of uranium ore in the entire sphere of control of the USSR. In 1991 after German reunification it was transformed into the Wismut GmbH company, owned by the Federal Republic of Germany, which is now responsible for the restoration and environmental cleanup of the former mining and milling areas. The head office of SDAG Wismut / Wismut GmbH is in Chemnitz-Siegmar. History The Ore Mountains (german: Erzgebirge; cs, Krušné hory) in southern East Germany at the border with the Czech Republic are closely connected to the history of uranium exploitation. The metal was discovered in a sample from a silver mine in the mountain range, and uranium was produced first as a by-product in the early ...

Post-war Years
In Western usage, the phrase post-war era (or postwar era) usually refers to the time since the end of World War II. More broadly, a post-war period (or postwar period) is the interval immediately following the end of a war. A post-war period can become an interwar period or interbellum, when a war between the same parties resumes at a later date (such as the period between World War I and World War II). By contrast, a post-war period marks the cessation of armed conflict entirely. Post–World War II Chronology of the post–World War II era The term "post-war" can have different meanings in different countries and refer to a period determined by local considerations based on the effect of the war there. Some examples of post-war events are (in chronological order) ;The Cold War (1947–1991) The Cold War was a geopolitical conflict between the capitalist and liberal democratic United States of America, the authoritarian and Communist Marxist–Leninist Union of Soviet Soc ...
