    Breakers and motor starters

    Greetings. I am new here and have found some very cool info so far. I have recently been scrapping breakers and starters. I have read here that there can be palladium found in breakers. I am having trouble distinguishing two types of contacts that I have found. One is obviously silver. The other is magnetic which is very confusing. Is palladium magnetic? How do I tell the difference between palladium and silver?

    Cheers

    If you are doing breakers and motor starters odds are you don't have Pd. if they are magnetic they might contain Ni. do you have any pics?

    I love these.

    Breakers like the panel box ones?
    Never thought of those. Have quite a few from my construction days in a box in the basement.

    House hold breakers contain silver but they are a lot of work to get at. Think .75-1g a pound in silver. Larger 480V have more but they are most of the time AgWx contacts about 40% silver.

    When it comes to precious metals never believe what you hear only what you see, a simple to make testing solution - stannous chloride becomes your eyes.

    Grab a copy of Hokes Refining Precious Metals Wastes from SCIBID, http://www.scribd.com/doc/2815953/Re...astes-C-M-Hoke

    Or read the info on the URL, Stannous Chloride

    DMG gives better results for palladium, http://goldrefiningforum.com/~goldre...hp?f=58&t=9158

    Testing precious metals by the same author, does not involve refining only how to identify a precious metal. http://www.scribd.com/doc/14426836/T...etals-CM-Hoke1

    Metal mike, you need more posts to be able to add pics (go say welcome to other newcommers), there is a thread on how to post a pic.
