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 ...

Cinnabar - Wikipedia
