Wheal Peevor
Wheal Peevor was a metalliferous mine located on North Downs about 1.5 miles north-east of Redruth, Cornwall, England. The first mining sett was granted here in around 1701 on land owned by the St Aubyn family. It was originally mined at shallow depths for copper, but when the price for that metal slumped after 1788, the mine was able to change to mining tin ore, which was found deeper down. In the late 18th century Wheal Peevor had the advantage of being drained by the Great County Adit which was around 100 metres deep here. The mine covered only 12 acres (4.8 ha) but had rich tin lodes. In addition to tin and copper, pyrite was also mined here between 1872 and 1887. History In 1790, the mine was considered part of Great North Downs mine; it was opened separately in 1872 as Wheal Peevor. By 1878 the mine was described as the ″surprise of Cornish mining″ because it was making a profit from tin while other Cornish mines were making a loss or closing. It was also described ...

Winch
A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a spool (or drum) attached to a hand crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called capstans. Despite this, sailboat capstans are most often referred to as winches. Winches are the basis of such machines as tow trucks, steam shovels and elevators. More complex designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. It might include a solenoid brake and/or a Mechanical brake stretch wrapper, mechanical brake or ratchet (device), ratchet and pawl which prevents it unwinding unless the pawl is retracted. The rope may be stored on the winch. When trimming a line on a sailboat, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Mines In Cornwall
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create bronze, c. 350 ...

World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain " cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. A ...

Cornwall And West Devon Mining Landscape
The Cornwall and West Devon Mining Landscape is a World Heritage Site which includes select mining landscapes in Cornwall and West Devon in the south west of England. The site was added to the World Heritage List during the 30th Session of the UNESCO World Heritage Committee in Vilnius, July 2006. Following plans in 2011 to restart mining at South Crofty, and to build a supermarket at Hayle Harbour, the World Heritage Committee drafted a decision in 2014 to put the site on the List of World Heritage in Danger, but this was rejected at the 38th Committee Session at Doha, Qatar (July 2014), in favour of a follow-up Reactive Monitoring Mission. History Up to the mid-16th century, Devon produced approximately 25-40% of the amount of tin that Cornwall did but the total amount of tin production from both Cornwall and Devon during this period was relatively small. After the 1540s, Cornwall's production took off and Devon's production was only about between a ninth to a tenth of that of C ...

Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...

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 ...

Great County Adit
The Great County Adit, sometimes called the County Adit, or the Great Adit was a system of interconnected adits that helped drain water from the tin and copper mines in the Gwennap area of Cornwall, in the United Kingdom. Construction started in 1748 and it eventually reached a length of over of a tunnel, providing drainage to over 100 mines at an average depth of . The adit was the brainchild of John Williams (born 1714) of Scorrier who was the manager of Poldice mine. Although work was started in 1748, it did not reach Poldice mine until the late 1760s. By 1778 the adit had been extended past Wheal Busy to Wheal Peevor, and another branch, known as the Consols Adit was driven west in the 1770s and 80s to drain the Consolidated Mines and United Mines. By 1792 a branch from Poldice extended to Wheal Unity. The portal of the adit is in the Carnon Valley below the hamlet of Twelveheads. In 1839, probably at its peak, it discharged over 14.5 million gallons (66 million litres) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
