Native aluminium metal is extremely rare and can only be found as a minor phase in low oxygen fugacity environments, such as the interiors of certain volcanoes. [71] Native aluminium has been reported in cold seeps in the northeastern continental slope of the South China Sea.
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.
For example, metallic cadmium was only found at two locations including the Vilyuy River basin in Siberia. [15] Native molybdenum has been found in lunar regolith and in the Koryakskii volcano in Kamchatka Oblast of Russia. [16] Elsewhere in this region native indium, aluminium, tantalum, tellurium, and other metals have been reported.
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.
Aluminium forms one stable oxide with the chemical formula Al 2 O 3, commonly called alumina. [15] It can be found in nature in the mineral corundum, α-alumina; [16] there is also a γ-alumina phase. [13]
Aluminum can prices vary by region and are based on weight. The average recycling value per pound of cans in the U.S. is currently $0.56. How many aluminum cans are in a pound?
Aluminium is soft and light, but it was soon discovered that alloying it with other metals could increase its hardness while preserving its low density. Aluminium alloys found many uses in the late 19th and early 20th centuries.
