Aluminium production process

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. The ore is loaded into autoclaves and treated with lime–caustic soda.

Bauxite Mining and Alumina Refining: Process Description

Some alumina refineries are located close to their bauxite mines. Bauxite mines typically employ 500 to 1000 people. PROCESS DESCRIPTION: ALUMINA REFINING. 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:
