Bauxite Used for Aluminum Production. 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.

Abstract A process for producing alumina from bauxite by the Bayer process. Bauxite slurry is pressure digested in caustic soda solution to dissolve aluminum hydroxides in the bauxite as sodium aluminate while leaving most of the remaining constituents of the bauxite in solid form as red mud. The red mud is separated from the digested slurry to obtain a causticaluminate pregnant liquor

2019719 Bauxite is the main source of the rare metal gallium.. During the processing of bauxite to alumina in the Bayer process gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ionexchange resin. Achievable extraction efficiencies critically depend on the original concentration in the feed bauxite.
