							<noteParagraph><text>Dans cette sous-classe, les groupes se rapportant à l'obtention de métaux comprennent l'obtention des métaux par des procédés non métallurgiques et l'obtention des composés métalliques par des procédés métallurgiques. Ainsi, p.ex. le groupe <sref ref="C22B0011000000" refType="/" refLevel="c"/> couvre la production de l'argent par réduction de l'oxyde d'argent ammoniacal en solution, et le groupe <sref ref="C22B0017000000" refType="/" refLevel="c"/> comprend la production de l'oxyde de cadmium par un procédé métallurgique. En outre, quoique les composés de l'arsenic et de l'antimoine soient classés en <sref ref="C01B" refType="/" refLevel="c"/>, la production des éléments eux-mêmes a été inscrite en <sref ref="C22B" refType="/" refLevel="c"/>, de même que la production de leurs composés par procédés métallurgiques.</text>
