Between 2008 and 2024, the energy intensity of metallurgical alumina refining dropped significantly from some * megajoules per metric ton of alumina in 2008 to just under * megajoules per metric ton of alumina in 2024. Once alumina has been refined from its ore, it may be used to produce aluminum or as a product itself in electronics.
