Aug 15, 2020 · Bauxite Ore Processing. Aluminum is found in varying amounts in nature as aluminosilies (contains aluminum, silicon, and oxygen) in various types of clay. As the minerals are weathered they gradually breakdown into various forms of hydrated aluminum oxide, Al 2 O 2 O, known as bauxite. The bauxite is purified by the Bayer Process. First ...

Aluminium production process

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 is refined to alumina using the Bayer process. This process relies on the principal that aluminium is an element with a high solubility in alkaline solution, whereas most of the other elements in bauxite ore (except silica) are not. The process uses sodium hydroxide to digest (leach) alumina from the bauxite.
