Bockau
Bockau is a community in the district of Erzgebirgskreis in the Free State of Saxony in Germany. The community is known for growing and researching herbs. Owing to its centuries-old cultivation of angelica, whose roots are used in making liqueurs, Bockau is also known locally by the nickname ''Wurzelbucke'' (''Wurzel'' is German for “root”). Geography Location The place lies in the western Ore Mountains in a sheltered hollow in a side valley off the Zwickauer Mulde valley, stretching up to the ''Ochsenkopf bei Jägerhaus'', an 823-m-high mountain. Neighbouring communities Bordering on Bockau are Aue, Lauter, Schwarzenberg, Sosa and Zschorlau. History In the late 15th century, farmers began gathering medicinal herbs from meadows and woods and to ply a trade with them. Important to the herbal lore were, among others, spignel, lovage, angelica, valerian and rhubarb. From the roots’ essential oils they mixed medicinal tinctures, essences and pills. Not least of ...

Schwarzenberg, Saxony
Schwarzenberg is a town in the district of Erzgebirgskreis in Saxony’s Ore Mountains, near the German–Czech border. The town lies roughly 15 km southeast of Aue, and 35 km southwest of Chemnitz. Founded in the 12th century to protect a trade road, the small mountain town became the centre of a territory known as '' Herrschaft Schwarzenberg'' and later ''Amt Schwarzenberg''. During the division of Germany, Schwarzenberg was part of East Germany and became the greatest producer of washing machines in Eastern Europe. Schwarzenberg became more widely known in 1987, when Stefan Heym coined the term Free Republic of Schwarzenberg for a small gap between the Soviet and American occupation zones in May/June 1945. Geography Schwarzenberg is in the southwestern Ore Mountains. It lies at elevations stretching from above sea level. The Old Town with church and castle is located on a rock (the Schlossberg, ) around which a meander of the River Schwarzwasser has formed; the ...

Zschorlau
Zschorlau () is a community in the district of Erzgebirgskreis in Saxony, Germany. Geography Location Zschorlau lies nestled in the gentle hills in the western Ore Mountains some 5 km from Aue and is overhung in the south by the ''Steinberg''. The community, as is so with many former forest homestead villages (''Waldhufendörfer'') in the Ore Mountains, grew up on a stream, in this case the Zschorlaubach, which rises southwest of the community on a broad moory plateau known in the local speech as ''Dr Forst'' or ''Hoher Forst'' (“The Forest” or “High Forest”). Before the stream reaches the community, its waters feed the Filzteich (pond), a popular recreation area. At the end of the community’s area at the Gößnitzgrund comes a glen through which the Zschorlauer Talstraße (Zschorlau Valley Road) was built in 1907. Also in this glen is found the ''St. Anna am Freudenstein'' visitor mine. Geology The community lies on the southeast flank of the ''Schneeberger ...

Sulphuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid ( Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula . It is a colorless, odorless and viscous liquid that is miscible with water. Pure sulfuric acid does not exist naturally on Earth due to its strong affinity to water vapor; it is hygroscopic and readily absorbs water vapor from the air. Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals, since it is an oxidant with powerful dehydrating properties. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid, but to the contrary dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is released; thus the reverse procedure of adding water to the acid should not be performed since the heat released may boil ...

Sulphur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrite
The mineral pyrite (), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Iron, FeSulfur, S2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic Luster (mineralogy), luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of ''fool's gold''. The color has also led to the nicknames ''brass'', ''brazzle'', and ''Brazil'', primarily used to refer to pyrite found in coal. The name ''pyrite'' is derived from the Greek language, Greek (), 'stone or mineral which strikes fire', in turn from (), 'fire'. In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what we now call pyrite. By Georgius Agricola's time, , the term had become a generic term for all of the pyrite group, sulfide minerals. Pyrite is usua ...

Medicine
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...
