Laterite - Wikipedia

Bauxite ore is the main source for aluminium.: 65 Bauxite is a variety of laterite (residual sedimentary rock), so it has no precise chemical formula. It is composed mainly of hydrated alumina minerals such as gibbsite [Al(OH) 3 or Al 2 O 3. 3H 2 O)] in newer tropical deposits; in older subtropical, temperate deposits the major minerals are boehmite [γ-AlO(OH) or Al 2 O 3.H 2 O] and some ...

Australian bauxite: Aluminium and beyond - Industrial Minerals

Australia is the world's largest producer of bauxite, with the majority used to produce alumina for the aluminium industry. Non-metallurgical applications such as refractories, proppants, building materials and pharmaceuticals make up around 10% of bauxite's end uses, however, and many Australian miners are looking at ways to diversify.

Mining and Refining – Process

The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.
