Abstract. Antimony has long been reckoned as a strategic metal. It is used today not only in metallic form, e.g. as an alloying element in lead, but also to an increasing extent in the form of Sb 2 O 3 as a flame retardant filler in plastics. The mineral raw material that provides nearly all the world's supply of antimony is stibnite, Sb 2 S 3.
