How is aluminum made?

Aluminum is made through a process called electrolysis. The primary source of aluminum is bauxite ore, which is first refined to produce aluminum oxide. This aluminum oxide is then dissolved in a molten cryolite bath and subjected to electrolysis. A large electric current is passed through the bath, causing the aluminum oxide to break down into aluminum metal and oxygen gas. The aluminum metal sinks to the bottom of the cell and is then tapped off and further processed. This process, known as the Hall-H茅roult process, is the predominant method for producing aluminum on an industrial scale.
