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]
This is a list of countries by primary aluminium production in 2023. [1] Primary aluminium is produced from aluminium oxide which is obtained from bauxite and excludes recycled aluminium. Only countries with a minimum production of 100,000 tonnes are listed.
Reddish-brown bauxite Bauxite with US penny for comparison QEMSCAN mineral maps of bauxite ore-forming pisoliths. Bauxite (/ ˈ b ɔː k s aɪ t /) is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.
Aluminum enters the biosphere through water and food as soluble aluminum, Al 3+ or AlF 2+. It is then cycled through the food chain. [1] Aluminum has a low abundance in the biosphere but can be found in all organisms. [1] Humans, animals, and plants accumulate aluminum throughout their lives as it cycled throughout the food chain.
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.
It is also commonly referred to as alumina or aloxite [1] in the mining, ceramic and materials science communities. It is produced by the Bayer process from bauxite. Its most significant use is in the production of aluminium metal, although it is also used as an abrasive due to its hardness and as a refractory material due to its high melting ...
Native aluminium (IMA1980-085a) is a natural occurrence of aluminium metal. Its (co)-type localities are the Billeekh intrusion and the dike OB-255, Sakha Republic . In a gabbro - dolerite of the Billeekh intrusion it occurs with copper , zinc , tin , lead , cadmium , iron , antimony and moissanite .
Three precious metals found in Earth's interior. Aquelium is a bright green metal derived from the interior ocean, and terrelium is a vermilion metal found only in Atvatabar. When these two metals come in contact, they produce a harnessable form of energy called magnicity. Arenak Skylark: A synthetic metal made by Osnomians.
