Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.
