Division 10Aluminium smelting

### Division 10—Aluminium smelting 310 (1) Aluminium smelting is the physical and chemical transformation of alumina (aluminium oxide (Al2O3)) into aluminium metal (Al) of saleable quality. (2) Aluminium smelting is specified as an emissions‑intensive trade‑exposed activity. (3) Aluminium smelting is a highly emissions‑intensive activity. > Note: See Part 4. (4) The basis for the issue of free carbon units is by a tonne of primary aluminium that: (a) has a concentration of aluminium of at least 98%; and (b) is produced as part of carrying on the emissions‑intensive trade‑exposed activity; and (c) is weighed after electrolysis but before casting.
