Aluminium – Tracking Industry 2019 – 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. The energy intensity of alumina refining decreased less in 2017 (‑2.8%) than in 2010‑16 (‑3.8% on average), while that of aluminium smelting declined more in 2017 (‑1.1%) than the 2010‑16 average
