Bauxites - «Mining Encyclopedia»

Bauxites are the main ore for the extraction of alumina (Al 2 O 3) and aluminium; they are used within the abrasive industry (electro-corundum), within the ferrous metallurgy (flux during the smelting of the open-hearth steel); the low-iron bauxites are used for the obtainment of the high-alumina mullitized refractories, of the fast-hardening alumina cements, and so on. Bauxites are the ...

Bauxite - Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small ...

The invention provides a method for modifying a Bayer process, processing low-grade diaspore bauxite and producing alumina. The method comprises steps that: (1) silicon is chemically pre-removed, wherein the low-grade bauxite is immersed into a sodium aluminate solution containing a stabilizing agent, such that a slurry containing dissolved silica is obtained; (2) obtained high-silicon sodium ...

This paper presents a review of existing and potential processes from the open literature that have been proposed for high silica bauxites. The processes have been divided into three strategies for reducing soda loss. These are (i) reduce the input of reactive silica into the process (ii) modify the process to produce a low soda residue and (iii) recover caustic soda by re-processing residue ...

Bauxite - AIMR 2013 - Australian Mines Atlas

Despite the low grade, the mines accounted for 23% of global alumina production as they also have low reactive silica, making the bauxite relatively easy to refine. Bauxite resources also occur in New South Wales (NSW) and Tasmania (Tas) but these are small (<25 Mt). More than 85% of the bauxite mined globally is converted to alumina for the production of aluminium metal. An additional 10% ...
