    Gold from Scrap Computer parts - anybody recover it?

    For the last few weeks, my co-worker and I have been pulling boards form scrap modems and radios. We tried the vinegar salt and peroxide method to recover some gold - it did free up some of the gold fingers but overall not that great

    I cut off some of the gold ends.

    now we have a box of scrap, a bucket with some scrap, and some cut off gold fingers, a bunch of connectors


    Does anybody here recover gold from computer parts?


    Would love to make a deal with somebody we would be willing to take a low percentage like 25% if somebody could recover the gold. We scrap a bunch of this stuff every year.. of course big question.. is it worth it????

    That's just a thin plating of gold on most parts as it's a good conductor and fairly inert, so is silver. Hard to separate from the other metals and the plastic crap. I'm sure you could work out a process, but it would be complex and involve chemicals that are hazardous. I think nitric acid would dissolve most metals and leave the gold. Nitric acid is nasty stuff........

    Looks like some coax connections in the mix, that's probably brass , unless some high end stuff.

    Thugs have been stealing catalytic converters from cars/trucks (SOBs use electric sawsalls) for the platinum catalyst scrap.

    Edit: Some humorous historical on Nitric acid.......

    The following is a passage from Ira Remsen (Prof. of Chemistry and Physics Williams College 1872-76) describing his introduction to chemistry.

    While reading a textbook of chemistry, I came upon the statement 'nitric acid acts on copper....'. I was tired of reading such absurd stuff, and I determined to see what this meant…. I was even willing to sacrifice one of the few copper cents in my possession. I put one of them on a table; opened the bottle marked ‘nitric acid’; poured some of the liquid on the copper and prepared to make observation. But what was this wonderful thing I beheld? The cent had already changed, and it was no small change either. A greenish blue liquid foamed and fumed over the cent and over the table. The air in the neighborhood of the performance became colored dark red. A great colored cloud arose. This was disagreeable and suffocating—how should I stop this? I tried to get rid of the objectionable mess by picking it up and throwing it out the window. I learned another fact—nitric acid acts not only on copper but it acts upon fingers. The pain led to another unpremeditated experiment. I drew my hands across my trousers and discovered the nitric acid acts upon trousers……….

    I have an old CPU with bent pins in with all my silver because of the gold plating on the pins in hopes that one day I will be able to remove it. Very interesting idea, but unless you are doing it large scale and are ok with toxic chemicals, I don't think it would be worth it too much for each person.
    I hope you figure out a good solution though! Maybe some science department at a school would like to show their students a cool chemical reaction to earn them money and they would front all the chemicals and do it safely.
