Aluminum is very important in construction, car and aircraft manufacturing, as well as in packaging due to its lightweight. The main ore of aluminum is bauxite, which is a combination of a number of minerals. The typical bauxite grade useable in the Bayer process consists of 50 - 55 % Al 2 O 3, up to 30% of Fe 2 O 3, and up to 1.5% of SiO 2.
