Hillgrove, New South Wales
Hillgrove is a Northern Tablelands (New South Wales) village with population of about 95. The village is located approximately 30 km east of Armidale and is 5 kilometres south of the Waterfall Way. Hillgrove is part of the Armidale Regional Council local government area and is in Sandon County. This historic goldmining town is situated at elevation of 1,000 metres on a granite plateau above Bakers Creek and near the Oxley Wild Rivers National Park. History The town was first known as ''Eleanora Township'', named after the antimony mine that for nearly a decade after 1876 was the sole reason for its existence. The name ''Hillgrove'' was given to the town in 1888. Hillgrove was one of the major gold fields in New South Wales, with a recorded production of over 15,000 kg of gold. It has also been a significant producer of antimony (14,700 tons) and tungsten (at least 2,000 tons of scheelite). Although some alluvial gold was discovered in Bakers Creek gorge as early as ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Towns In New England (New South Wales)
A town is a human settlement. Towns are generally larger than villages and smaller than cities, though the criteria to distinguish between them vary considerably in different parts of the world. Origin and use The word "town" shares an origin with the German word , the Dutch word , and the Old Norse . The original Proto-Germanic word, *''tūnan'', is thought to be an early borrowing from Proto-Celtic *''dūnom'' (cf. Old Irish , Welsh ). The original sense of the word in both Germanic and Celtic was that of a fortress or an enclosure. Cognates of ''town'' in many modern Germanic languages designate a fence or a hedge. In English and Dutch, the meaning of the word took on the sense of the space which these fences enclosed, and through which a track must run. In England, a town was a small community that could not afford or was not allowed to build walls or other larger fortifications, and built a palisade or stockade instead. In the Netherlands, this space was a garden, more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining Towns In New South Wales
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, and fi ...

Australian Gold Rushes
During the Australian gold rushes, starting in 1851, significant numbers of workers moved from elsewhere in Australia and overseas to where gold had been discovered. Gold had been found several times before, but the colonial government of New South Wales (Victoria did not become a separate colony until 1 July 1851) had suppressed the news out of the fear that it would reduce the workforce and so destabilise the economy. After the California Gold Rush began in 1848, many people went there from Australia, so the New South Wales government sought approval from the British Colonial Office for the exploitation of mineral resources, and offered rewards for finding gold. History of discovery The first gold rush in Australia began in May 1851 after prospector Edward Hargraves claimed to have discovered payable gold near Orange, at a site he called Ophir. Hargraves had been to the Californian goldfields and had learned new gold prospecting techniques such as panning and cradling. H ...

Wyong
Wyong () is a town in the Central Coast of New South Wales, located approximately 63 km SSW of Newcastle and 89 km NNE of Sydney. Established in 1888, it is one of the two administrative centres for the local government area. History Wyong is an indigenous word meaning either 'an edible yam' or 'place of running water'. William Cape was the first European settler to settle in the area and bring cattle and sheep into the district, on a land grant bordering Jilliby Creek in 1825. Cape had two sons who also held land grants.

Mount Barney National Park
Mount Barney National Park is a national park in Queensland (Australia), 90 km southwest of Brisbane. It amalgamated the adjacent Mount Lindesay (Queensland), Mount Lindesay National Park in 1980.

Register Of The National Estate
The Register of the National Estate was a heritage register that listed natural and cultural heritage places in Australia that was closed in 2007. Phasing out began in 2003, when the Australian National Heritage List and the Commonwealth Heritage List were created and by 2007 the Register had been replaced by these and various state and territory heritage registers. Places listed on the Register remain in a non-statutory archive and are still able to be viewed via the National Heritage Database. History The register was initially compiled between 1976 and 2003 by the Australian Heritage Commission, after which the register was maintained by the Australian Heritage Council. 13,000 places were listed. The expression "national estate" was first used by the British architect Clough Williams-Ellis, and reached Australia in the 1970s.Heritage of Australia, pp. 9–13 It was incorporated into the ''Australian Heritage Commission Act 1975'' and was used to describe a collection o ...

Scheelite
Scheelite is a calcium tungstate mineral with the chemical formula Ca W O4. It is an important ore of tungsten (wolfram). Scheelite is originally named after Swedish chemist K. Scheele (1742-1786). Well-formed crystals are sought by collectors and are occasionally fashioned into gemstones when suitably free of flaws. Scheelite has been synthesized using the Czochralski process; the material produced may be used to imitate diamond, as a scintillator, or as a solid-state lasing medium. It was also used in radium paint in the same fashion as was zinc sulphide, and Thomas Edison invented a fluoroscope with a calcium tungstate-coated screen, making the images six times brighter than those with barium platinocyanide; the latter chemical allowed Röntgen to discover X-rays in early November 1895. Properties Its crystals are in the tetragonal crystal system, appearing as dipyramidal pseudo-octahedra. Colors include golden yellow, brownish green to dark brown, pinkish to reddish ...

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 ...
