Aluminium recycling is the process in which secondary commercial aluminium is created from scrap or other forms of end-of-life or otherwise unusable aluminium. [1] It involves re-melting the metal, which is cheaper and more energy-efficient than the production of virgin aluminium by electrolysis of alumina (Al 2 O 3 ) refined from raw bauxite ...
The aluminium industry began promoting the recycling of aluminium cans in an attempt to avoid restrictions on them. [103] This sparked recycling of aluminium previously used by end-consumers: for example, in the United States, levels of recycling of such aluminium increased 3.5 times from 1970 to 1980 and 7.5 times to 1990.

Nine-year pro Jalen Ramsey has a chance at a revenge game on "Monday Night Football" as his Dolphins take on his former team, the Los Angeles Rams.
Additionally, one of the main motifs of boron chemistry is regular icosahedral structures, and aluminium forms an important part of many icosahedral quasicrystal alloys, including the Al–Zn–Mg class. [42] Aluminium has a high chemical affinity to oxygen, which renders it suitable for use as a reducing agent in the thermite reaction.
