  • How Is Aluminum Extracted From Its Ore?

     · Aluminum is extracted from bauxite ore by way of the Bayer process. This requires a great deal of electricity; consequently, a large amount of aluminum is processed in Iceland, which gets its electricity through geothermal energy. To extract aluminum, the bauxite ore is first crushed, then mixed with lime, hot water and soda ash.
