Impeller from a three-stage air compressor. An impeller, or impellor, [1] is a driven rotor used to increase the pressure and flow of a fluid. It is the opposite of a turbine, which extracts energy from, and reduces the pressure of, a flowing fluid. Strictly speaking, propellers are a sub-class of impellers where the flow both enters and leaves ...
The facility, New Zealand's only aluminium smelter, [3] is at Tiwai Point, near Bluff. It imports alumina and processes it into primary aluminium. The plant's alumina is supplied from refineries in Queensland and the Northern Territory of Australia. Around 90 per cent of the aluminium produced at NZAS is exported, mainly to Japan.
Mozal is an aluminium smelter joint project in Beluluane Industrial Park, Maputo, Mozambique. [2] The project is a smelting facility that began operations as a producer of aluminium exclusively for export. The smelter is located 20 kilometres (12 mi) west of the city of Maputo in the south of the country. Mozal was a joint venture between BHP ...

The Tomago aluminium smelter is located at Tomago, New South Wales, Australia, approximately 13 km west of Newcastle, within the Port Stephens LGA. The smelter has a production capacity of 590,000 tonnes of aluminium (ingot, billet and slab) per year. [1] It is operated by Tomago Aluminium Company, an independently managed joint venture owned ...
Aluminium ( Aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
Category. : Aluminium smelters. Wikimedia Commons has media related to Aluminium smelters. The Aluminium smelters category lists the primary aluminium smelters of the world. Aluminium is produced in over 200 smelters in approximately 40 countries.
The vast majority of compounds, including all aluminium-containing minerals and all commercially significant aluminium compounds, feature aluminium in the oxidation state 3+. The coordination number of such compounds varies, but generally Al 3+ is either six- or four-coordinate. Almost all compounds of aluminium (III) are colorless.
