In the Earth's crust, aluminium is the most abundant metallic element (8.23% by mass [33]) and the third most abundant of all elements (after oxygen and silicon). [65] 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]
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.
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.
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 ...

Aluminium was used heavily in aircraft production and was a strategic material of extreme importance; so much so that when Alcoa (successor of Hall's Pittsburgh Reduction Company and the aluminium production monopolist in the United States at the time) did not expand its production, the United States Secretary of the Interior proclaimed in 1941 ...

The aluminum industry in the United States in 2023 produced 860 thousand metric tons of aluminum from refined metal ore (primary production), at six smelters. In addition, US industry recycled 3.4 million tons of aluminum (so-called secondary production aluminum). [ 1 ]
