Alcoa World Alumina And Chemicals
Alcoa World Alumina and Chemicals is a joint venture between Alumina Limited (40% share) and Alcoa (60% share) and is abbreviated to AWAC. AWAC's business is the mining of bauxite, the extraction of alumina ( aluminium oxide) and the smelting of aluminium. It has about 25% of the global alumina market. Alcoa acts as the day-to-day manager. Australian operations Alcoa has two smelters in Victoria, located at Portland and Point Henry in Victoria.

Alumina Limited
Alumina Limited is an Australian holding company. Spun off from Western Mining Corporation in 2002, its sole asset is a 40% shareholding in Alcoa World Alumina & Chemicals. History Alumina was founded in December 2002 when Western Mining Corporation spun off its aluminium and bauxite assets. Alumina's only business activity is as the owner of a 40% share in Alcoa World Alumina & Chemicals (AWAC), a joint venture with Alcoa. AWAC owns two bauxite mines and three refineries (to extract aluminium oxide from bauxite) in Western Australia and owns a smelter (to extract pure aluminium metal) and has a 55% interest in the Portland aluminium smelter. AWAC also has operations or interests in Brazil, Guinea, Saudi Arabia and Spain. In 2016, Alumina Limited achieved great short term authority over its interest in AWAC with more influence over a broader suite of operational and investment decisions. Having been a dual-listed company with shares on both the Australian Securities Exchan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wagerup, Western Australia
Wagerup is a town located in the Peel region of Western Australia just off the South Western Highway. It is located between Waroona and Harvey, south of Waroona. History The town's name was initially spelt Waigerup or Waigeerup, derived from an Aboriginal name meaning "the place of the emu" (waitch), and was applied to a brook in the area. The same spelling was used when the railway station opened in 1896. However, by 1899, when the townsite was gazetted, the current spelling had been adopted (according to local legend, the man who painted the sign for the railway station misspelt the name). In the mid 1970s serious community concern about impending mining in jarrah forests saw considerable protests about the construction of the Wagerup refinery. The Campaign to Save Native Forests and South West Forests Defence Foundation challenged the planned mining venture, and the conditions under which Alcoa was to be mining. Present day Alcoa have operated an alumina refinery in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium Companies Of Australia
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards ox ...

Aluminium Smelting
Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery. This is an electrolytic process, so an aluminium smelter uses huge amounts of electric power; smelters tend to be located close to large power stations, often hydro-electric ones, in order to hold down costs and reduce the overall carbon footprint. Smelters are often located near ports, since many smelters use imported alumina. Layout of an aluminium smelter The Hall-Héroult electrolysis process is the major production route for primary aluminium. An electrolytic cell is made of a steel shell with a series of insulating linings of refractory materials. The cell consists of a brick-lined outer steel shell as a container and support. Inside the shell, cathode blocks are cemented together by ramming paste. The top lining is in contact with the molten metal and ...

Anglesea Power Station, Victoria (Australia)
The Anglesea Power Station was a brown coalpowered thermal power station located at Anglesea, in Victoria, Australia. The station had one steam turbine, with a capacity of . It was operated by Alcoa of Australia and supplied almost 40% of the electricity used by the company's Point Henry aluminium smelter, until the smelter's closure in August 2014. The power station was brought online on 20 March 1969, and was supplied with brown coal from the adjacent open cut mine, transported to the power station along a -long private road. Overburden was stripped and backfilled into the mined area by earthmoving contractors, using conventional power shovels and trucks. About 80 people worked at the mine and power station.Murphy, Noel, 20 February 2014, 80 jobs in doubt at Alcoa’s Anglesea power station'', The Independent, Retrieved 28 August 2014 In June 2015, Alcoa announced that the power plant and mine would close at the end of August 2015, after the company was unable to find a buyer ...

Lignite
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials may be present in lignite which are left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinjarra, Western Australia
Pinjarra is a town in the Peel region of Western Australia along the South Western Highway, from the state capital, Perth and south-east of the coastal city of Mandurah. Its local government area is the Shire of Murray. At the 2016 census, Pinjarra had a population of 4910. Pinjarra is an area rich in history, and is the home town of a former State Premier - Sir Ross McLarty. It is near the site of the Pinjarra massacre, where between 14 and 80 Noongar people were killed by British colonists in 1834. History The name was often shown spelt "Pinjarrup" on early maps, while the accepted spelling for many years was "Pinjarrah". There are conflicting theories regarding the meaning of the name, and it is usually said to mean "place of a swamp", as a corruption of the Aboriginal word "beenjarrup". However, Pinjarra is more likely to have been named after the Pindjarup people who frequented the area. Pinjarra is one of the earliest European settlements to occur in Western Aust ...
