How aluminium is extracted using electrolysis
WebAluminum Electrolysis. Although aluminum is abundant in nature, it occurs chemically bound to other elements, and there is no known way to smelt aluminum using traditional smelting methods. Because of this limitation, before the 19 th century, pure aluminum was rarer than gold. In the 19 th century, people learned how to use electrolysis to ...
