About Bauxite

Characteristics

Non-ferrous metallic mineral
Principal ore of aluminium
Generally reddish-brown, white, grey or yellow in colour
Composed mainly of hydrated aluminium oxides (gibbsite, boehmite, diaspore)
Lightweight, low-density but high-strength (via aluminium extraction)
Formed by intense chemical weathering (laterisation) in tropical and subtropical climates
Occurs as residual deposits, not associated with veins or lodes
Typically found on plateaus, uplands and hilltops

Uses

Aluminium used in transport, construction, and packaging)
Electrical transmission lines and cables
Aircraft, automobiles, ships and rail coaches (lightweight metal)
Packaging industry (cans, foils)
Defence, aerospace and renewable energy sectors
Alumina is used in refractories, abrasives, cement and chemicals

World’s largest producer: Guinea
