Too reactive to be reduced by carbon
Aluminium
Bauxite
Al2O3Al_2O_3Al2O3
Lowers the melting point of the bauxite mixture
Graphite
Al3+Al^{3+}Al3+ ions gain electrons (reduction)
Al3++3e−→Al(l)Al^{3+} + 3e^- \rightarrow Al(l)Al3++3e−→Al(l)
O2−O^{2-}O2− ions lose electrons (oxidation)
2O2−→O2(g)+4e−2O^{2-} \rightarrow O_2(g) + 4e^-2O2−→O2(g)+4e−
Denser than the surrounding mixture
Oxygen gas and carbon dioxide
