How is aluminium extracted by electrolysis

WebAluminium is the most abundant metal on Earth, but it is expensive, largely because of the amount of electricity used in the extraction process. Aluminium ore is called bauxite (Al 2 O 3). The bauxite is purified to yield a white powder – aluminium oxide (also known as alumina) – from which aluminium can be extracted. Web4. Electrolysis In the electrolysis department, the zinc contained in the solution is deposited onto aluminum cathodes in a process called electrowinning. This happens by passing an electric current through cathodes and anodes. The cathodes are removed from the cells and the zinc sheets are stripped from the cathodes and sent to casting.
