Primary metal manufacturing

331 - Primary metal manufacturing

This subsector comprises establishments primarily engaged in smelting and refining ferrous and non-ferrous metals from ore, pig or scrap in blast or electric furnaces. Metal alloys are made with the introduction of other chemical elements. The output of smelting and refining, usually in ingot form, is used in rolling and drawing operations to produce sheet, strip, bars, rods and wire, and in molten form to produce castings and other basic metal products.

• Exclusion(s)

  • manufacturing metal forgings or stampings(332)

3314 - Non-ferrous metal (except aluminum) production and processing

This industry group comprises establishments primarily engaged in smelting, refining, rolling, drawing, extruding and alloying non-ferrous metal, except aluminum.

• Exclusion(s)

  • smelting, refining, rolling, drawing, extruding and alloying aluminum (See 3313 Alumina and aluminum production and processing)

33141 - Non-ferrous metal (except aluminum) smelting and refining

This industry comprises establishments primarily engaged in smelting non-ferrous metals, except aluminum, from ores; and refining these metals by electrolytic or other processes. Establishments engaged in secondary activities, such as rolling or extruding basic shapes, from metal produced in the same establishment, are included.

331410 - Non-ferrous metal (except aluminum) smelting and refining^US

This Canadian industry comprises establishments primarily engaged in smelting non-ferrous metals, except aluminum, from ores; and refining these metals by electrolytic or other processes. Establishments engaged in secondary activities, such as rolling or extruding basic shapes, from metal produced in the same establishment, are included.
