kilometre bauxite mining lease by the Western Australian Government. In December 1961, ground was broken for the Kwinana Alumina Refinery near Perth and the Point Henry Aluminium Smelter and a semifabriing plant near Geelong in Victoria. This was an immense project at the time. The expenditure for initial production capacity was 50 per cent more than the combined market value of the three ...
SUSTAINABLE SOLID/LIQUID SEPARATION
bauxite slurry caustic soda • Red mud, named after its color, is the main byproduct of making alumina by the Bayer process • The red mud is separated from the pregnant liquor (sodium aluminate remains in solution) via sedimentation in a clarifier • The amount of red mud (as dry matter) varies from ton to 2 ton per ton of alumina product, depending on the quality of the bauxite ...

bauxite is ready to be mined. An excavator or loader is used to load the bauxite onto haul trucks for transport to the crusher. The crusher is used to break the ore down to a smaller size suitable for transport along conveyor belts to the refineries.

Predesiliion and digestion of gibbsitic bauxite with ...
· The effect of lime on the predesiliion and digestion of gibbsitic bauxite in synthetic sodium aluminate liquor at different temperatures was investigated. The bauxite is comprised of gibbsite, aluminogoethite, hematite, kaolin, quartz, and minor boehmite. Lime increases the desiliion efficiency of the bauxite during the predesiliion process by promoting the conversion of sodalite ...

Chapter 2. Production and Processing of Aluminum
Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH) 3 in lateric bauxite. Besides these compounds, bauxite contains iron oxide, which usually gives it a reddishbrown colour, as well as silies (clay, quartz) and titanium oxide. The crys tal structure also contains 12–20% by ...
Mining and Refining – Process
The bauxite is washed and crushed, reducing the particle size and increasing the available surface area for the digestion stage. Lime and "spent liquor" (caustic soda returned from the precipitation stage) are added at the mills to make a pumpable slurry. 2. Desiliion. Bauxites that have high levels of silica (SiO 2) go through a process to remove this impurity. Silica can cause problems ...
