Bauxite is one of the world''s most abundant minerals and is strip-mined in many places. Nearly all is processed into alumina for aluminium production. Bauxite contains iron-bearing clay or red mud, which often leaves stains on the hold paint that can prove difficult to remove. Bauxite is an aluminium ore and is the main source of aluminium.
· "Drilling usually occurs a week ahead of blasting and involves several drilling machines to produce a 5 m x 5 m (16 ft x 16 ft) grid of boreholes," Shiliang explained. "Around a week after the drilling process is complete, we will then come through and blast. Around 55 000 - 110 000 t of bauxite is extracted each time.

· A new process is suggested in the present work turning bauxite residue (BR) into a ready-made mortar for the synthesis of inorganic polymers, effectively transforming the Bayer process into a zero-waste process. This was achieved by firing BR at 1100 °C which supports the formation of liquid phase and results after subsequent fast cooling in a semivitreous material.
· Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides that formed from intense chemical weathering of a soil in tropical environments. Soils formed under these conditions are termed laterites. In Arkansas, the aluminum-enriched soils are the result of the decomposition and lateritic weathering of nepheline syenite, an intrusive igneous rock. During the ...
