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.
ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites.
Bauxite is transported by any number of means including off and on road trucks, rail, conveyor systems, ships and even as piped slurries. Typical mining and transport equipment.
