Gold from Scrap Computer parts - anybody recover it?
This is a discussion on Gold from Scrap Computer parts - anybody recover it? within the Economic, Precious Metals, Investing, Finance forums, part of the General Discussion category; 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 ...

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.
I prefer to let our Indian friends reap the rewards....

I have a large box of this stuff now...
there are some good videos on youtube about this process.
i looked into it before i got sick, it is involved and uses two different acids if i remember correctly.
the amount of gold recovered is minute so large amounts of raw material are needed.
having said that... if a person with access to the raw materials and the ability to follow directions,
the end results would be gold you did not have before.
i tried to post links but could not... check out youtube

if I knew now what I knew then... I'd be a lot happier. think about it
