Aluminium | Geoscience Australia

Bauxite is the most common aluminium ore. Bauxite occurs as a weathered cover or blanket, known as laterite or duricrust, over a variety of alumina-bearing rocks. It forms when large amounts of rainfall leach away the more mobile elements in the host rock leaving the relatively immobile aluminium with some silicon, iron and titanium.

Bauxite - aluminium from laterites - Earth Sci

After many millions of years what is left is called a "laterite", which can be either iron-rich, or in extreme cases, aluminium-rich (i.e. bauxite). Most lateritic bauxites were formed in a period from the mid-Cretaceous to the late-Tertiary, that is, 100 million to 2 million years ago. During this time, laterite formation was not continuous.
