Bauxite Processing Equipment For Ceramic Additives

Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to bauxite mines and/or ports for efficient transport of raw materials and of the final product.

The addition of finely divided solid fuel to bauxite charge has been proposed as a strategy for improving the technical and economic parameters of the process of sintering bauxite charge in a rotary furnace. The additive, which marginally deteriorates the quality of the initial components, contributes to the development of internal crystallochemical transformations in …

Bauxite is a mineral that contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant. It is found in a belt around the equator and is generally extracted by open-cast mining. ... this is done by filter cake. Chemical additives are added to assist the sedimentation process ...

The Bayer process is the most commonly used refinement route, though certain countries use alternatives called the combined or parallel Bayer-Sinter process and the Nepheline-based process [20, 37].This section describes purely the Bayer Process. Due to the impurities in the bauxite ore, it requires treatment to produce purer alumina, Al 2 O 3 [18].This is achieved by …

In the lime sinter process the additive is a calcium salt ... have the same objective with respect to high silica bauxite processing, i.e. they both allow the digestion of bauxite at temperatures sufficiently lower than normal for boehmitic ores, to reduce the degree of quartz attack (and therefore soda loss). ... Journal of the American ...
