Mining and Refining – Process
Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location Before mining can commence the land needs to be cleared of timber and vegetation Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which There are currently five bauxite mines in Australia providing feedstock for the seven alumina refineries, which in turn supply alumina to the six Australian aluminium smelters and the export market Australia is the largest producer of bauxite in the world, with 749 million tonnes produced in 2011Australian Bauxite The Australian Aluminium CouncilFeb 12, 2018 An overview of our bauxite position on Australia’s Cape York Duration: Rio Tinto 23,216 views 5:33 The Mining Process at Copper Mountain Mine Duration: 7:13 CopperMountainMining Producing Endless Possibilities: Alcoa Global Bauxite

Mining Extraction of aluminium metal takes place in three main stages¿mining of bauxite ore, refining the ore to recover alumina and smelting alumina to produce aluminium Bauxite is mined by surface methods (opencut mining) in which the topsoil and overburden are removed by bulldozers and scrapersThe Bayer process, discovered in 1887, extracts alumina from bauxite through crushing, dissolving it in caustic soda, filtration and an electrolytic process A white powder, similar to table salt, called alumina is produced and can then be smelted into aluminium metal to be used in things like cars, packaging, powering the nation and consumer AluminaAustralia is the largest producer of bauxite, followed by China In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuriesBauxite Wikipedia
