Physical Properties and Uses of Bauxite
geology/minerals/bauxite.shtmlHow Bauxite is used to make aluminum?Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.
Bauxite: The principal ore of aluminum.
geology/minerals/bauxite.shtmlHow is bauxite made?The ore must first be chemically processed to produce alumina (aluminum oxide). Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide.

How alumina is produced from bauxite?The bauxite ore contains aluminum trihydrate (Al (OH) 3 ). Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3: The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite.
