• Sources of Antimony:

  Found in stibnite (Sb₂S₃) and in valentinite (Sb₂O₃). World wide production is around 53,000 tons per year. Primary mining areas are China, Italy, Peru, Mexico, Bolivia and France.

• Uses of Antimony:

  Used to harden lead alloy's. Also used in solder, bearings, lead batteries, mascara, infrared detectors, plastics and chemicals.

• Additional Notes:

  Antimony used to be used to provoke vomiting, but the medical dose was too close to the fatal dose. Small does stimulate metabolism, but large doses cause liver damage and can kill.
