Worsley, Western Australia
Worsley is a town in Western Australia located in the South West region near the town of Collie. The town is within the Shire of Collie. The town's name comes from the Worsley River, a tributary of the Collie River, which is located nearby. The river was named after Charles Anderson-Pelham, Lord Worsley, a member of the Western Australian Land and Emigration Committee, which also included James Stirling, John Hutt, William Hutt (MP), Edward Barrett-Lennard and Captain Bunbury. The committee promoted emigration to the Swan River colony and the Western Australian Land Company, which established the Australind land settlement project in 1841 under Marshall Waller Clifton. The name was first recorded in surveys performed in the area in 1845. In the 1890s a railway siding was constructed in the area to service the timber industry, and later in 1906 the state government decided to create a town-site in the area. Lots were surveyed in 1907 and the town was gazetted in 1909. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
States And Territories Of Australia
The states and territories are federated administrative divisions in Australia, ruled by regional governments that constitute the second level of governance between the federal government and local governments. States are self-governing polities with incomplete sovereignty (having ceded some sovereign rights to federation) and have their own constitutions, legislatures, departments, and certain civil authorities (e.g. judiciary and law enforcement) that administer and deliver most public policies and programs. Territories can be autonomous and administer local policies and programs much like the states in practice, but are still constitutionally and financially subordinate to the federal government and thus have no true sovereignty. The Federation of Australia constitutionally consists of six federated states (New South Wales, Queensland, South Australia, Tasmania, Victoria, and Western Australia) and ten federal territories,Section 2B, Acts Interpretation Act 1901 out of ...

Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ea ...

Bauxite
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). Bauxite appears dull in luster and is reddish-brown, white, or tan. In 1821, the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and Jamaica above carbonate rocks (limestone and do ...

Boddington, Western Australia
Boddington is a town and Shire of Boddington, shire in the Peel (Western Australia), Peel region of Western Australia, located south-east of Perth. The town sits on the road from Pinjarra, Western Australia, Pinjarra to Williams, Western Australia, Williams on the Hotham River. The population of the town was 1,844 at the 2016 Census. History The town owes its name to an early settler, Henry Boddington, who was a farmer and shepherd in the 1860s and 1870s and leased land in the area in 1875, later moving to Wagin, Western Australia, Wagin. His name became associated with a pool in the Hotham River at which he frequently camped. The original settled locality was called Hotham, west of the town at what is now the end of Farmers Avenue, named for the Farmer family, and a post office and school were established. When the Hotham Valley Railway was being constructed in 1912 to meet demand created by the local timber industry, a townsite was chosen adjacent to the town, and subsequen ...

Bunbury, Western Australia
Bunbury is a coastal city in the Australian state of Western Australia, approximately south of the state capital, Perth. It is the state's third most populous city after Perth and Mandurah, with a population of approximately 75,000. Located at the south of the Leschenault Estuary, Bunbury was established in 1836 on the orders of Governor James Stirling, and named in honour of its founder, Lieutenant (at the time) Henry Bunbury. A port was constructed on the existing natural harbour soon after, and eventually became the main port for the wider South West region. Further economic growth was fuelled by completion of the South Western Railway in 1893, which linked Bunbury with Perth. Greater Bunbury includes four local government areas (the City of Bunbury and the shires of Capel, Dardanup, and Harvey), and extends between Yarloop in the north, Boyanup to the south and Capel to the southwest. History Pre-European history The original inhabitants of Greater Bunbury are the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bayer Process
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al2O3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be further purified before it can be refined into aluminium metal. Process Bauxite ore is a mixture of hydrated aluminium oxides and compounds of other elements such as iron. The aluminium compounds in the bauxite may be present as gibbsite 2(Al(OH)3), böhmite (γ-AlO(OH)) or diaspore (α-AlO(OH)); the different forms of the aluminium component and the impurities dictate the extraction conditions. Aluminum oxides and hydroxides are amphoteric, meaning that they are both acidic and basic. The solubility of Al(III) in water is very low but increases substantially at either high or low pH. In the Bayer process, bauxite ore is heated i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
