    As you can plainly see ... they're mostly carbon once you get them all ground up. Actual silver recovery seems to be in the 2.5 - 3 % range if your process is good. About a pound of silver from the batch pictured above.

    About $ 300.00 gross. Maybe $ 200.00 net after expenses ?

    I dunno ... beats me ... i guess the proof is in the putting. The best thing would be to get the processing done from start to finish and take the end product to market. It would definitely be worth 19 grand if that's what someone would pay you for it.

    Another way you could look at it.

    40 lbs is about 580 troy ounces. Silver is about $ 33.28 / troy ounce today. Do the math and it works out to $ 19,302.40.

    The brushes would have to be pure silver bullion ready to sell on the open market for your 19 k. figure to work.

    ~ It's just common sense. ~

    The brush's I have contain 70% silver, not all types of brushes contain silver.

    Depending on application silver content can go as high 95% silver.

    SILVER GRAPHITE

    Silver graphite has a material content of 8 – 95% silver. The added conductivity and lower voltage drop, allows metal graphite brushes to operate at very high current densities and low voltages.

    Interesting link. I guess it all comes down to knowing exactly what kind of brush was used in the machine that it came out of. That's kinda hard to do ... ya know ?

    You are probably looking at the big money, highly sophisticated stuff, like generators in power plants and large electrical motors found in industry. A random box of graphite brushes could be most anything.

    Anyhow ... talk is just talk. It don't amount to much really. It's that actual doing it from start to finish that matters most. I hope it works out for you. It would be a good money scraping thing if it can be made to work. Even lower yields would be a nice little side gig for an older gent that knows how to do the refining.

    ETA : Just a suggestion .... but it's something you might want to keep to yourself if it does pan out. It seems like anytime people get the idea in their head that money is involved ... they all want to get in on the act.

    The less competition you have for the resource ... the better.

    Starter motor brush's testing for silver, once heated some silver sweated out from the carbon.
