Bauxite: The principal ore of aluminum.
The aluminum hydroxide is then calcined to form alumina, Al 2 O 3. Aluminum is smelted from the alumina using the Hall-Heroult Process. In the Hall-Heroult Process, the alumina is dissolved in a molten bath of cryolite (Na 3 AlF 6). Molten aluminum is removed from the solution by electrolysis. This process uses an enormous amount of electricity.
