Electrolysis is the preferred method for extracting aluminium over other methods because aluminium oxide (Al₂O₃) is not easily reduced by chemical methods. Other methods, such as reacting aluminium oxide with carbon, require very high temperatures and are economically unviable.

The electrolysis process provides a direct and efficient way to obtain pure aluminium. The molten state of the electrolyte ensures good electrical conductivity, leading to a high current efficiency. Furthermore, the process produces a high-purity aluminium product.
