• |
Aluminum ore, called bauxite, is most commonly formed in deeply weathered rocks
|
• |
Approximately 95% of the world's bauxite production is processed into aluminium
|
• |
Bauxites are heated in pressure vessels with sodium hydroxide solution at 150-200 °C through which aluminium is dissolved as aluminate
|
• |
Most materials used for transportation use large amounts of aluminum: cars, trucks, boats, aircraft, and aircraft engines
