This is the preferred method to extract these metals, though, because alternative methods are far more expensive. For example, the first attempts to extract aluminum (or aluminium, if you prefer) by Ørsted, Berzelius and Wöhler between the 1820's and 1845 reacted potassium with aluminum compounds. The metal thus produced was costly, valued ...
