They are also used for the extraction of aluminium from bauxite. Another notable application of electrolytic cells is in electroplating, which is the process of forming a thin protective layer of a specific metal on the surface of another metal. The electrorefining of many non-ferrous metals is done with the help of electrolytic cells.
