Batts Combe Quarry
Batts Combe quarry, is a limestone quarry on the edge of Cheddar village on the Mendip Hills, Somerset, England. It has been operating since the early 20th century and is currently owned and operated by Singleton Birch Ltd. The output in 2005 was around 4,000 tonnes of limestone per day, one third of which was supplied to an on-site lime kiln, the remainder being sold as coated or dusted aggregates. The limestone at this site is close to 99% carbonate of calcium and magnesium (dolomite). In former years it was a major supplier of limestone for railway track ballast purposes. A lime-burning kiln at the site was closed for a while in 2006 after testing showed quicklime dust was escaping into the atmosphere. The kiln, which produced 200,000 tonnes of quicklime a year for use in the steel industry, required £300,000 of investment to resolve the problems. The closure followed an earlier warning from the Environment Agency when the company was notified that it should tighten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Calcium Oxide
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "''lime''" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. By contrast, ''quicklime'' specifically applies to the single chemical compound calcium oxide. Calcium oxide that survives processing without reacting in building products such as cement is called free lime. Quicklime is relatively inexpensive. Both it and a chemical derivative ( calcium hydroxide, of which quicklime is the base anhydride) are important commodity chemicals. Preparation Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above ,Me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarries In The Mendip Hills
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk * China clay * Cinder *Clay *Coal * Construction aggregate (sand and gravel) * Coquina * Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone * Marble * Ores *Phosphate rock *Quartz *Sandstone * Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarries Of The Mendip Hills
The Mendip Hills, (Mendips) in northern Somerset, are the most southerly Carboniferous Limestone uplands in Britain. The Mendips comprise three major anticlinal structures, each with a core of older Devonian sandstone and Silurian volcanic rocks. The latter, after crushing, is use in road construction and concrete. Devonian Sandstone is visible around Black Down and Downhead. Carboniferous Limestone, dominates the hills and surround the older rock formations. An outcrop of basalt is also quarried at Moon's Hill. For centuries the stone of the Mendips, and the Cotswolds to the north, have been used to build the cities of Bristol and Bath, and many Somerset towns. As stone transportation is expensive, the Mendips, and Leicestershire, are important as the nearest sources of hard stone for London and the South East. The Mendip quarries produce twelve million tonnes of stone a year, employ two thousand people, and have an annual turnover of £150m. Five million tonnes of s ...

Dormice
A dormouse is a rodent of the family Gliridae (this family is also variously called Myoxidae or Muscardinidae by different taxonomists). Dormice are nocturnal animals found in Africa, Asia, and Europe. They are named for their long, dormant hibernation period of six months or longer. As only one species of dormouse – the hazel dormouse – is native to the United Kingdom, in everyday English usage "dormouse" can refer either to that one species or to the family as a whole. The English name of the species derived from the French ''dormeuse'', and the latter in turn possibly from the Languedocien ''radourmeire''. Etymology Concerning the dormouse's name, etymonline says "long-tailed Old World rodent noted for its state of semi-hibernation in winter, early 15c., possibly from Anglo-French ''dormouse'' 'tending to be dormant' (from stem of ''dormir'' 'to sleep,' see ''dormant''), with the second element mistaken for ''mouse''; or perhaps it is from a Middle English dialectal c ...

Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end of ...

Dolomite (rock)
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 million years in age). The first geologist to distinguish dolomite rock from limestone was Belsazar Hacquet in 1778. Most dolomite was formed as a magnesium replacement of limestone or of lime mud before lithification. The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past geologic record in contrast to the limited amounts of dolomite formed in modern times. Recent research has revealed sulfate-reducing bacteria living in anoxic conditions precipitate dolomite which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnesium
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium. In the cosmos, magnesium is produced in large, aging stars by the sequential addition of three helium nuclei to a carbon nucleus. When such stars explode as supernovas, much of the magnesium is expelled into the interstellar medium where it m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
