Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH)3 in lateric bauxite. Besides these compounds, bauxite contains iron oxide, which usually gives it a reddish-brown colour, as well as silicates (clay, quartz) and titanium oxide.
