    2015-6-19  Antimony is produced from minerals. The most important mineral source of the metal is stibnite (antimony trisulfide), but it is also found in trace amounts in silver, copper and lead ores (EU-RAR 2008). Antimony trioxide is obtained by roasting stibnite ores (Sb 2 S 3) which are reported to contain 55% antimony (IARC 1989).

    2020-7-25  The mineral breithauptite (NiSb) contains nickel and the semimetal antimony, which acts as the electronegative, nonmetallic element of the compound. Breithauptite is thus an antimonide. The mineral calaverite (AuTe2), in turn, contains the metallic element gold and the semimetal tellurium, which provides an anion; calaverite is a telluride.
