Sintered bauxite is used in drilling for oil and natural gas by hydraulic fracturing. The reservoir rock is often fractured by pumping fluids into the well under extremely high pressures. The rocks in shale reservoirs crack, allowing water and bauxite "proppants" to rush in. The proppant particles clog the reservoir cracks when the pumps are shut.

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 ...

Bauxite — after smelting by Hall-Herault process — is converted into alumina. Alumina can be used and converted into casts or sheets. Compared to other metals, aluminium is very light, yet strong, durable, tough and good conductor. Replacing iron, copper and other metals in various fields, it became the champion metal of the 20th century.

Since 2002, China has developed over 50Mt of alumina refining capacity. Chinese alumina production was based on two approaches: • Development of merchant refining capacity in Shangdong based on imported Indonesian bauxite. • Processing of domestic ore. New refining capacity has lead to record increase in bauxite demand and imports.

An electrical current is run through the mixture, causing the carbon from the carbon anode to attach to the oxygen component in the alumina, yielding aluminum and carbon dioxide: 2 Al2O3 + 3 C > 4 Al + 3 CO2. This process takes place at temperatures between 940-980º C and yields an aluminum of high purity.
