    Hi Yuivak, 

>      I have some 24k gold powder which has been slightly contaminated

    If I were you, I'd try a magnet. Get the strongest magnet  you can
    find. 

    Make sure the mixture is dry & if there are any lumps in it
    pulverize them so you truely hae a mixture of fine particles. 

    Spread the mixture out on a non magnetic surface (glass or ceramic,
    etc) in as thin a layer as possible. 

    Keeping the magnet as close to the mixture as possible, but not
    touching, pass the magnet over the mixture in from one end to the
    other in overlapping rows until the entire surface has been gone
    over. 

    To ensure an even coverage, go over the mixture a 2nd time. This
    time from side to side (at 90 degrees to the 1st). 

    This should method should remove the iron in the mixture. 

    Dave

    Yuvak, The first inclination I'd have would be to use a magnet to
    pick up all the iron particles, leaving behind the gold.  You'll
    want to sift through it a few times to make sure you've gotten all
    the iron out, but this should work, since gold is not magnetic. 

    Good luck! Karen Goeller kgoeller AT nolimitations.com

    If it isn't mechanically bonded then use a magnet, that's what is
    done when making filings for soldering filigree work the "American
    Indian" way. 

    A lurker, Brian.

    G'day.    Get a good magnet, cover it in tissue or polythene and
    after making sure the powder is quite dry, drag it over the powder
    until it picks up no more iron..    Renew the covering when and if
    necessary.

    Use a magnet.  Of course this will only work for your iron in the
    gold and not silver.
