331313 Alumina Refining and Primary Aluminum Production

This U.S. industry comprises establishments primarily engaged in one or more of the following: (1) refining alumina (i.e., aluminum oxide) generally from bauxite; (2) making aluminum from alumina; and/or (3) making aluminum from alumina and rolling, drawing, extruding, or casting the aluminum they make into primary forms. Establishments in this industry may make primary aluminum or aluminum-based alloys from alumina.

Cross-references. Establishments primarily engaged in--
  • Manufacturing aluminum oxide abrasives and refractories--are classified in Subsector 327, Nonmetallic Mineral Product Manufacturing; and
  • Recovering aluminum from scrap or alloying purchased aluminum--are classified in U.S. Industry 331314, Secondary Smelting and Alloying of Aluminum.
