  • Sources of Ruthenium:
    Found in pentlandite and pyroxinite. Produced as a by-product of nickel refining. Around 0.12 tons are produced world wide on an annual basis. Primary mining areas are South Africa, Russia, Canada, USA and Zimbabwe.
  • Uses of Ruthenium:
    Used to harden platinum and palladium. Also used in eye treatments, thickness meters for egg shells, fountain pen points, and electrical contacts. Aircraft magnetos use platinum alloy with 10% ruthenium.
  • Additional Notes:
    Some sources credit G.W. Osann of discovering ruthenium at the University of Tartu Russia in 1928, but this is was really only a "rediscovery".
