Aluminium: ores • It occurs as bauxite ore which is a form of aluminium oxide. • Because aluminium is so reactive carbon is unable to pull away the oxygen from it. • It is extracted by electrolysis of moltenmolten bauxite. Early attempts at this failed because bauxite is so hard to melt. • If cryolite is added, the bauxite melts more easily.

How Aluminium is extracted from bauxite? Aluminium ore is called bauxite. The bauxite is purified to yield a white powder, aluminium oxide, from which aluminium can be extracted. The extraction is done by electrolysis. But first the aluminium oxide must be made molten so that electricity can pass through it.

aluminum is bauxite. Bauxite consists of 45-60% aluminum oxide, along with various impurities such as sand, iron, and other metals. Although some bauxite deposits are hard rock, most consist of relatively soft dirt that is easily dug from open-pit mines. Australia produces more than one-third of the world's supply of bauxite.
