The waste solid, bauxite tailings, is removed and aluminium hydroxide is precipitated from the remaining solution of sodium aluminate. This aluminium hydroxide can be converted to aluminium oxide or alumina by calcination. The residue or bauxite tailings, which is mostly iron oxide, is highly ...
In addition to this method, the industrial synthesis entails the initial preparation of sodium aluminium hydride from the elements under high pressure and temperature: Na + Al + 2 H2 → NaAlH4 LiAlH4 is then prepared by a salt metathesis reaction according to: ...
