Coopers Creek, Victoria
Coopers Creek is a locality and mine in the Gippsland region of Victoria, Australia. In the 1860s, Coopers Creek was settled during the Victorian gold rush and, throughout its history, gold, copper and lime have been mined there. Today, Coopers Creek is effectively limited to two camping sites, the first near the site of the mining town and the second to the east at Bruntons Bridge. Ruins from the locality's mining history, and the Copper Mine Hotel are all of the locality's history which survives. In August 2022, the 21 properties that comprise the town were listed for sale. Geography Coopers Creek is in the Shire of Baw Baw in Victoria's Gippsland region. It is located in the Great Dividing Range, in the steep forested slopes of the Thomson River valley. The original township was located around the confluence of the Thomson River and Coopers Creek which is where mining operations were centred. The area gazetted as Coopers Creek is partially bounded by the Thomson River and by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erica, Victoria
Erica is a town in Victoria, Australia, on Rawson Road, in the Shire of Baw Baw. The area was generally known as Upper Moondarra in the early 1900s, the township of Erica beginning to grow after construction of the railway line from Moe to Walhalla, which passed through the area. When the station opened in 1910 it was named Harris, but had been renamed Erica after a nearby mountain by 1914. As a consequence, the Post Office opened on 14 July 1910 as Upper Moondarra and was renamed Erica in 1914. The township of Erica lived mainly from forestry and agriculture, and owing to Walhalla's decline by the 1920s was the largest town on the Moe-Walhalla railway. The section of line past Erica closed to traffic in 1944, save for occasional goods services to Platina station, and the line from Moe to Erica closed completely in 1954. The Erica Court of Petty Sessions closed in 1968. Erica still maintains agricultural and timber industry connections, as well as being a service town for ...

Silver
Silver is a chemical element; it has Symbol (chemistry), symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native metal, native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in currency and as an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarry
A quarry is a type of open-pit mining, open-pit mine in which dimension stone, rock (geology), rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to manage their safety risks and reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. History For thousands of years, only hand tools had been used in quarries. In the eighteenth century, the use of drilling and blasting operations was mastered. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Scoria, Cinder *Clay *Coal *Construction aggregate (sand and gravel) *Coquina *Diabase *Gabbro *Granite *Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone *Slate *Travertine Methods of quarrying The method of removal of stones from their natural bed by using different operations is called quarryin ...

Lime (material)
Lime is an Inorganic compound, inorganic material composed primarily of calcium oxides and hydroxides. It is also the name for calcium oxide which is used as an industrial mineral and is made by heating calcium carbonate in a kiln. Calcium oxide can occur as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities in the manufacture of steel and as building and engineering materials (including limestone products, cement, concrete, and mortar (masonry), mortar), as chemical feedstocks, for sugar refining, and other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for was ...

Happy-Go-Lucky, Victoria
Pearson was a town in Victoria, Australia, located southwest of Walhalla. It was in the local government area of the Shire of Baw Baw The Shire of Baw Baw () is a local government area in Victoria, Australia, in the eastern part of the state. It covers an area of and in 2021 had a population of 57,626. It includes the towns of Drouin, Longwarry, Neerim South, Trafalgar .... It was also known as The Happy, and Happy Go Lucky. The town's history began with the discovery of a quartz reef outcrop or 'blow' by prospector William McGregor in 1863. McGregor was cutting an access track into the mining town of Walhalla when he came across this feature. He examined the rock but failed to find any gold in it. He later showed this to a workmate William Cummin, whose sharper eyes noted that this was not the case. Cummin kept this discovery to himself and soon after he left McGregor's prospecting party and went to Seaton to register a prospecting claim on the site. He later gave ...

Australian Science And Technology Heritage Centre
The Australian Science and Technology Heritage Centre (Austehc), lasted from 1999 to 2006, was a non-profit organisation that received the majority of its funding from collaborative works with the government and industry groups. Austehc was a part of the Department of History and Philosophy of Science at the University of Melbourne. The main purpose and objective of the centre was to help preserve all the historical works relating to Australian science, technology, and medicine. By utilising more advanced technology, all the information within the centre could be easily accessed by anyone. Originally, Austehc was called the Australian Science Archives Project (ASAP), but was later changed after facing some challenges in May 1999. Their two most popular projects were Bright Sparc, which was developed in 1994, and Australian Science at Work, developed in 1999. Later on, these two projects merged with each other and became known as Encyclopedia of Australian Science during the time o ...

Walhalla Railway Line
The Walhalla railway line was a Narrow gauge railway, narrow gauge railway located in Gippsland, Victoria (Australia), Victoria, Australia. The line ran from Moe, Victoria, Moe to the former gold-mining town and popular tourist destination of Walhalla, Victoria, Walhalla. Construction began in 1904. The line closed in sections from 1944 to 1954. History The last of the four narrow gauge lines of the Victorian Railways to be opened, construction of the Moe–Walhalla railway began in 1904 but was not completed until 1910 due to the difficult mountainous terrain to be contended with. The railway was expected to be a boon for the town, which was in a state of economic and population decline due to gold mining operations becoming increasingly uneconomical, with the largest gold mining company closing in 1914. However, the arrival of the railway did not save the town. After the closure of the Walhalla mines, substantial timber traffic was carried from sawmills in the Erica ar ...

Metallurgical Furnace
A metallurgical furnace, often simply referred to as a furnace when the context is known, is an industrial furnace used to heat, melt, or otherwise process metals. Furnaces have been a central piece of equipment throughout the history of metallurgy; processing metals with heat is even its own engineering specialty known as pyrometallurgy. One important furnace application, especially in iron and steel production, is smelting, where metal ores are Redox, reduced under high heat to separate the metal content from mineral gangue. The heat energy to fuel a furnace may be supplied directly by fuel combustion or by electricity. Different processes and the unique properties of specific metals and ores have led to many different furnace types. Air blast furnaces Many furnace designs for smelting combine ore, fuel, and other reagents like flux in a single chamber. Mechanisms, such as bellows or motorized fans, then drive pressurized blasts of air into the chamber. These blasts make the ...

Kilns
A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles and bricks. Various industries use rotary kilns for pyroprocessing (to calcinate ores, such as limestone to lime for cement) and to transform many other materials. Etymology According to the Oxford English Dictionary, kiln was derived from the words cyline, cylene, cyln(e) in Old English, in turn derived from Latin ''culina'' ('kitchen'). In Middle English, the word is attested as kulne, kyllne, kilne, kiln, kylle, kyll, kil, kill, keele, kiele. In Greek the word ''καίειν, kaiein'', means 'to burn'. Pronunciation The word 'kiln' was originally pronounced 'kil' with the 'n' silent, as is referenced in ''Webster's Dictionary of 1828'' and in ''English Words as Spoken and Written for Upper Grades'' by James A. Bowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mill (grinding)
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically, mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind ( windmill) or water (watermill). In the modern era, they are usually powered by electricity. The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
