    Does anyone know of an honest reputable Gold Refinery that has much
    expertise/proficiency in processing Electronic Integrated Circuits
    (IC) chips/components for Gold Recovery/Reclamation? Or does anyone
    know how to find such information.

    Why would you expect to find gold in ICs ?

    The tiny little wires that conned the circuits ons the chips to the
    pins are made of pure gold. They are extremely small. You'd need to
    open up a heck of a lot of chips to get just one gram of gold. OMU

    Most of the old ICs have gold bond wires in addition to the Au/Si die
    attach material. Many of them used a Gold/Tin solder to attach the
    metal lid. There are tons of these old ICs out there that are heading
    for land fills.

    It has been a few years since I saw any ads by refineries. I suspect
    many of the old MIL grade components are finding their way to China for
    recycling into new MIL grade component!

    For a lot of plastic packaged ICs they are gold bondwires. I was surprised
    to find that this is especially true for a lot of high pin-count ICs used
    in consumer products.
