Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the Caribbean, South America and Australia. Australia is the largest producer of bauxite, with five large mines supplying around 30 per cent of global production. Bauxite mining has five steps: preparation of the mining area; bauxite mining; crushing; ore transport; and; rehabilitation

Australian bauxite deposits have high grades and are shallow and relatively easy to mine. To learn more about the bauxite mining process go to our Bauxite Mining Chart. The quality of Australian bauxite means there are a number of small new mines either operating or in the exploration and approvals phase in Australia including: VBX; Bauxite Hills
catchment areas, but Alcoa is mining the bauxite to within 200 metres of the water's edge at one of the dams, the South Dandalup Dam, which provides Perth with its purest drinking water. In addition, Alcoa's mining operations are destroying the irreplaceable Jarrah forest for ever. It is doing this in two ways. Firstly, mining operations
Alcoa’s Mining and Restoration Process in South Western. 12/12/2007 This paper describes the sequence of Alcoa’s bauxite mining and restoration operations in Western Australia, commencing with pre‐mining surveys and geological exploration through to the preparation and extraction of the bauxite ore, the restoration process, and then monitoring These methods have changed continually
The award was presented at the 2010 Australian Engineering Excellence Awards which took place in Canberra, Australia. Oxalate forms in the alumina refining process as a result of organic material in bauxite ore. Organics enter the refinery liquor stream when bauxite is digested in caustic soda
Mining Process Alcoa’s bauxite mining operations in Western Australia occur in the Darling Range. The bauxite occurs as a result of a lateritic weathering process and is often found on the sides of the hills. To access the bauxite there are a number of steps involved in the mining process
Restoration Following Bauxite Mining In Western Australia . Paul W. Hinds . Introduction . The Darling range of south-western Australia is the world’s leading producer of aluminum, accounting for approximately 38% of the world production in 1994 (Matlox 1999). In 1995/96
May 01, 2014 The bauxite ore, Bayer process materials before precipitation, mud residue, and sand residue are therefore of radiological interest, whereas the alumina product is not.8 Positional and personal monitoring data from bauxite mines and alumina refineries in Western Australia have been used to assess the above-background annual doses for the
