Concentration of ore. The bauxite ore contains ferric oxide and silica as impurities. Gravity separation removes silica from crushed ore and magnetic separation separates ferric oxide impurities from the ore. The ore is then concentrated by a chemical process. Bauxite is the name given to aluminium ore.

Bauxite Formula. The most common metal on Earth is aluminium, but it is costly, mainly because of the amount of energy required in the production process. Bauxite (Al 2 O 3) is called aluminium ore. The bauxite is purified to yield a white powder from which aluminium can be extracted-aluminium oxide (also known as alumina).
