### Division 8—Smelting zinc 308 (1) Smelting zinc is the chemical transformation of either or both of: (a) concentrated mineralised zinc compounds; and (b) zinc‑bearing secondary materials; to produce zinc metal (Zn) with a concentration of zinc of at least 99.95%. (2) Smelting zinc is specified as an emissions‑intensive trade‑exposed activity. (3) Smelting zinc 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 zinc that: (a) has a concentration of zinc of at least 99.95%; and (b) is produced by carrying on the emissions‑intensive trade‑exposed activity; and (c) is of saleable quality. > Note: Saleable quality is explained in Part 2.
