A large number of silicates in the Earth's crust contain aluminium. [66] In contrast, the Earth's mantle is only 2.38% aluminium by mass. [67] Aluminium also occurs in seawater at a concentration of 0.41 µg/kg. [68] Because of its strong affinity for oxygen, aluminium is almost never found in the elemental state; instead it is found in oxides ...
Most of the aluminum on Earth is located in the mantle and crust of the lithosphere. [3] From various processes, this aluminum is uplifted through the soil and into the biotic cycle. Most notably, humans find mineral deposits of aluminum in the earth and dig it up to use in various products.
Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal, in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminium metal is too reactive chemically to occur natively. Instead, it is found combined in over 270 different minerals. [7] The chief ore of aluminium is ...
The Earth's crust is one "reservoir" for measurements of abundance. A reservoir is any large body to be studied as unit, like the ocean, atmosphere, mantle or crust. Different reservoirs may have different relative amounts of each element due to different chemical or mechanical processes involved in the creation of the reservoir.
Renaissance scientists believed that alum was a salt of a new earth; during the Age of Enlightenment, it was established that this earth, alumina, was an oxide of a new metal. Discovery of this metal was announced in 1825 by Danish physicist Hans Christian Ørsted , whose work was extended by German chemist Friedrich Wöhler .

Zones with highest aluminium content are frequently located below a ferruginous surface layer. The aluminium hydroxide in the lateritic bauxite deposits is almost exclusively gibbsite. In the case of Jamaica , recent analysis of the soils showed elevated levels of cadmium , suggesting that the bauxite originates from Miocene volcanic ash ...
