Who / Where / When / How

  • Discoverer: Known to pre-Columbian South Americans. Taken to Europe around 1750
  • Discovery Location: South America
  • Discovery Year: Unknown
  • Name Origin:
    Spanish: platina (little silver).
  • Abundance of Platinum:
    • Earth's Crust/p.p.m.: 0.001
    • Seawater/p.p.m.:
      • Atlantic Suface: N/A
      • Atlantic Deep: N/A

  • Sources of Platinum:
    Produced from platinum ore or native platinum deposits. Primary mining areas are Urals in Russia, Canada, South Africa Columbia and Peru. Annual world wide production is around 30 tons.
  • Uses of Platinum:
    Used in jewelry, to make crucibles, special containers, as a catalyst, in dental crowns, as an anti-tumor agent and to make standard weights and measures. It is also combined with cobalt to produce very strong magnets.
  • Additional Notes:
    Some sources attribute the discovery of platinum to Antonio de Ulloa of Spain in 1735 or Wood in 1741, however, it had been known to and used by the pre-Columbian Indians in South America long before that time. For this reason we have opted to credit the first users of platinum with the discovery, not the European explorers/scientists that "rediscovered" it and brought it to Europe.
