- FACTS
- - Aluminum ore is known as bauxite. - Electrolysis is used in the purification of aluminum. - It is the second most abundant metallic element in the Earth's crust after silicon. - Aluminum oxidizes very easily and pieces of aluminum are normally coated with a layer of aluminum oxide. - The metal was first extracted by Hans Christian Ørsted in 1825.
