Aluminium – Analysis - IEA

Primary aluminium production involves two key steps: alumina refining, to refine bauxite ore into alumina (aluminium oxide), and aluminium smelting, to convert alumina to pure aluminium. Average annual drops in alumina refining energy intensity for 2019 and 2020 were similar to those during 2010-2018 (an average 3.0% per year).
