How is aluminum extracted from aluminum oxide
WebThe chromium (III) oxide is reduced to chromium by O loss, the aluminium is oxidised to aluminium oxide by O gain, and the aluminium is the reducing agent i.e. the O remover. These are examples of metal displacement reactions e.g. the less reactive chromium or titanium are displaced by the more reactive sodium, magnesium or aluminium. WebThe extraction process ( digestion) converts the aluminium oxide in the ore to soluble sodium aluminate, NaAlO 2, according to the chemical equation : Al 2 O 3 + 2 NaOH → 2 NaAlO 2 + H 2 O This treatment also dissolves …
