The raw material for the Bayer process is most commonly mined bauxite, a rock containing aluminium, which – as we already know – also contains many other substances (admixtures) in addition to aluminium oxide hydrates‑, such as iron‑, titanium and silicon oxides in particular. The main task of the process is to remove these admixtures.
