Eve,

    you can etch the iron out using hydrochloric/ muriatic acid..... And
    then clean the piece and try re pickling in normal sparex/ sulfurous
    acid type pickle, if you have an ultrasonic at your disposal it
    wouldn't hurt to run it thru.... 

    Side note: if the iron gets back into the sparex type pickle it will
    cause electro deposition of the dissolved copper... Aka copper
    electroplate on the surface of the piece..... 

    If you have access to nitric acid you can try a quick etch in there
    it will also eat the iron off and the copper.... 

just my 2 cents,
Jon P
