331410 Nonferrous Metal (except Aluminum) Smelting and Refining

This industry comprises establishments primarily engaged in (1) smelting ores into nonferrous metals and/or (2) the primary refining of nonferrous metals (except aluminum) by electrolytic methods or other processes.

Cross-References. Establishments primarily engaged in--
  • Mining and making copper and other nonferrous concentrates (including gold and silver bullion), by processes, such as solvent extraction or electrowinning--are classified in Industry Group 2122, Metal Ore Mining;
  • Recovering copper or copper alloys from scrap or dross and/or alloying, rolling, drawing, and extruding purchased copper--are classified in Industry 331420, Copper Rolling, Drawing, Extruding, and Alloying;
  • Rolling, drawing, and/or extruding nonferrous metal shapes (except copper and aluminum) from purchased nonferrous metals (except copper and aluminum) or by recovering nonferrous metals (except copper and aluminum) and rolling, drawing, or extruding--are classified in U.S. Industry 331491, Nonferrous Metal (except Copper and Aluminum) Rolling, Drawing, and Extruding;
  • Recovering nonferrous metals (except copper and aluminum) from scrap and making primary forms and/or alloying purchased nonferrous metals (except copper and aluminum)--are classified in U.S. Industry 331492, Secondary Smelting, Refining, and Alloying of Nonferrous Metal (except Copper and Aluminum);
  • Making aluminum from alumina--are classified in U.S. Industry 331313, Alumina Refining and Primary Aluminum Production;
  • Operating facilities where commingled recyclable materials, such as paper, plastics, used beverage cans, and metals, are sorted into distinct categories without also smelting or refining--are classified in Industry 562920, Materials Recovery Facilities; and
  • Sorting, breaking up, and wholesaling scrap metal without also smelting or refining--are classified in Industry 423930, Recyclable Material Merchant Wholesalers.
