Aluminium (or aluminum) metal is very rare in native form, and the process to refine it from ores is complex, so for most of human history it was unknown. However, the compound alum has been known since the 5th century BCE and was used extensively by the ancients for dyeing .
The great expense of refining the metal made the small available quantity of pure aluminium more valuable than gold. [16] Bars of aluminium were exhibited at the Exposition Universelle of 1855, [17] and Napoleon III's most important guests were given aluminium cutlery, while those less worthy dined with mere silver.

This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero. For elements whose radiological properties are important, individual isotopes and isomers are listed. The price listing for radioisotopes is not exhaustive.
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 ]
