However, aluminum is the primary component of many minerals, the most common being bauxite. Bauxite is a mixture of aluminum oxides and hydroxides. Other minerals containing aluminum include:
* Feldspar: A group of minerals containing aluminum, silicon, oxygen, and various alkali and alkaline-earth metals.
* Kaolinite: A clay mineral containing aluminum, silicon, oxygen, and hydrogen.
* Corundum: A crystalline mineral composed of aluminum oxide, found in various forms including ruby and sapphire.
* Cryolite: A mineral containing sodium, aluminum, and fluorine.
So, while aluminum itself isn't a mineral, it's a major component in various minerals.
