Difference Between Bauxite and Aluminum ...

Bauxite is a sedimentary rock type, which is the mineral ore of aluminum. It mostly contains aluminum hydroxide, Al(OH) 3 and aluminum oxide (it is a mixture of gibbsite, boehmite and diaspore). In addition, there are iron oxides, hydroxides and other trace material mixed in it too.

CHEMICAL-MINERАLOGICAL CHARACTERIZATION OF BAUXITES …

Although it is often classified as a mineral, bauxite is a sedimentary rock, a polymineral aggre-gate composed of aluminium hydroxides known as mineral hydrargilite (gibbsite) Аl(OH)3, boehmite АlOOH and diaspore AlOOH. These three minerals are the main components of bauxite. The chemical and mineralogical composition varies within very wide limits. Depending on the mineralogical form of the ...
