HISTORY

FROM RED EARTH TO SILVERY METAL

HistoryBauxite, aluminium's ore is the third most abundant compound in the Earth's crust. The Bayer process of refining bauxite is used to obtain most commercially produced alumina. In this process, the bauxite is refined to aluminium-oxide which is mixed with cryolite and then electrolytically reduced to pure aluminium. The end product is a hard and strong, silvery-white metal with an oxide layer that protects the metal and eliminates the need for finishing.
