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.

The chemistry of steelmaking. The big picture.

Most workable iron ores are rich in iron (III) oxide, Fe 2 O 3. Making iron by removing oxygen from the ore is the first step in the manufacture of steel. Reduction and oxidation: Removing oxygen chemically from a substance is called reduction. The industrial production of iron involves reducing iron (III) oxide in a Blast Furnace. Most of the
