High Grade Circuit Boards Gold Recovery FAILED EXPERIMENT
Вставка
- Опубліковано 15 бер 2024
- I will attempt to recover gold and silver from 7 lb high grade circuit boards. I will show most of the process except the chemistry step is where I will loose a lot of gold due to my lack of knowledge and experience, and I do learn a lot from my mistakes to make this step way better in the future projects.

I really like how you are testing different things. Every time I see one of your videos not work it saddens me because I want you to have success. Please don’t give up! Please keep experimenting.
Thanks. Right now I'm working on dry air vacuum separation system, I plan to post it maybe in like 3 hours from now. It's a work in progress and it has weaknesses but it works.
Interesting! You do so well on the difficult parts (grinding the material to a fine powder) yet you make the simple part, the chemistry unnecessarily complicated. I love what you are doing with the grinding and metal recovery with the blue bowl but would love to see you go the next stem with the electronics processing and recover all the precious metals!
Good luck
Love the electrolysis for copper before going to chemicals and your hammer mill is excellent, nice one. I’d look to go for a finer powder for the blue bowl and run it with only material in the same classification (30/50/80/100 mesh separately from each other). the chemistry part definitely speak with Pete (above) but would still be worth letting us see your full process anyway. I know I made mistakes on my RAM video but the feedback has been invaluable to fine tune some things and look at my own thinking to reassess. it’s difficult to suggest some alternatives without seeing how you got there. Want to finish on a good positive though, your recovery method is top notch and your equipment will certainly help going forward, keep up the good work
I have the same setup.i use the 1 inch wide and put a sharp edge on it .takes off most things.u can hook up a shop vac on side port to keep air cleaner an dust down.put a piece of plywood down and a 2x4 screwed to it to put boards on and not mess up the side of sand blaster.the blue bowl is picky if there is oils to mess up surface tension plus sailboat gold thats light will not stay in.dream matts has a mat to put on bottom to help trap gold.i only use the blue bowl for placer mining gold.nice video.
If you have trouble with the chemistry you can always ask me for advice. My whole channel is about helping people
Hey Pete, I appreciate your offer. Before the aqua regia, my nitric boils were successful, it's the aqua regia where I began having problems. During aqua regia I used distilled water in my sprayer bottle, when I would spray the sides to get junk back into the solution, I would get milky cloudy forming where I sprayed, and the more I sprayed and the more I added distilled water the more thicker the white milky cloud formed. It could have been copper chloride in my later research because I was running low on hydrochloric acid in the solution to keep it in liquid form. That's when I began filtering it out not knowing what it was, and still I don't, it was just a theory based on my research. Now I had lots of filter paper to deal with, then boiled them in aqua regia after adding more hydrochloric, from there I lost track of how much hydrochloric and nitric was in there because that milky stuff threw me off. Anyway after filtering it with hydrochloric acid I was somewhat successful in keeping that white milky stuff liquid. Then SMB dropped a lot of that dark brown stuff with very little gold, I don't know what that brown stuff is and where did most of my gold went to. Let me know more info based on my description and I appreciate it. In the future, I'm thinking after the nitric boils, I will go straight to cupeling. Let me know thanks.
@MetalScrapLab hmmm I've never experienced the white milky stuff from spraying water. That sure sounds strange.
Could it have been silver falling out of solution ?
As for the smb, did you use food grade or chemical grade ?
If you bought it from a acid supplier or a hardware store then any brown precipitate should be gold.
But if its food grade and the brown you talk about is kind of like a burgundy colour then try dissolving it water first.
I use food grade and I can't add it dry or I get a horrible burgundy colour through the solution and a burgundy skin on the surface which is hard to filter. But as soon as I started dissolving it first I stopped having that problem.
I dont like cupelling myself. I prefer the chemistry, but that's just me. Many people love cupelling.
I hope this helps
The SMB I used is the same one sreetips uses, by stump out by bonide. The cupeling is actually interesting to me and fairly easy, it's the chemistry that I struggle with. But as soon as I get better at it, then chemistry will become more fun for me but for now its stressing me out as a step. I appreciate for your response. I'll get back to you in the future if I run into issues again.
@@MetalScrapLab you have to film everything, because now it's treatment over the phone :)... it could be metacynic acid, a very nasty thing when refining gold. During electrolysis, I would put a larger copper plate on the wire, this would increase the electrode surface and most of the copper would dissolve.
Potrebbe essere lo stagno che crea quella cosa lattiginosa?
Sounds like there is a small amount of chorine in your DI water . Test it pour a sample if the distilled water out add some silver nitrate if it cloudy it the chorine in the DI water forming silver chloride
Excellent video! The chemistry is the easiest part . The labor to get there is the hardest 😊.there isn't much gold in newer electronics but plenty of copper
Thank's BRO.great job
Very good work🎉
You seem to have skills, i imagine you are capable of much more. Advice... buy clean presirted scrap next time. Harvesting and seperating parts and material is 90% of the work. You have some amazing tools (or man toys), you can increase your yield with a better, cleaner process. 👍
Well, this looks like industrial degree recycling method... Hard to do small scale method in big scale and vice versa... Very interesting...
Good video, could you take it down another micron level? from the debris, looked like a golden glaze on the crucible. Can you incinerate it again after 1st grind after 1st incineration after getting plastics out?
Nice boards
Good interesting video 👍
This is a fantastic video! Great job on the camera work and editing. That stuff isn’t easy to “just do”. A fair amount of planning and time must have gone into it so I’d like to acknowledge that. Also, you certainly have impressive tools for a small scale recycler. You utilize many processes I’ve only read about that the large refiners use. And great job on the environmentally conscience vapor capture effort. I know that’s where you feel like you messed up and lost gold. That’s a hard pill to swallow when you’ve put so much thought to it. Maybe try venting non pressurized fumes into a large air chamber with basic fluid misting through it? I can’t comment much about your chemistry process without seeing more of it other than to say i think you’re right about a second electrolysis to remove more copper, and I think your white cloudy”stuff” is likely Cu(I)Cl if adding more HCl or more heat redissolves it. I don’t use electrolysis yet, It takes me two weeks sometimes to remove base metals (including Cu), and that’s sometimes not long enough. I’m sure you understand all that and copper recovery is part of your process. You got good gold for what you stated with. I didn’t see any high gold content components like gold corner BGAs, but the array pattern on the PCB shows where they used to be. Looks like someone already removed the high value components (BGAs, thin and thick quad packages). Unless I missed it, from a gold recovery perspective, you processed mostly dual inline packages and pins. Not much gold there, so I think you did a great job for what you started with. Keep up the great work and videos. Your production is impressive!
I appreciate for the comment, your attention to detail is very good. I will keep trying to improve on every step of process for maximum efficiency.
Mi sono iscritto perche trovo interessante i tuoi video. Poi volevo anche chiederti se ci fai vedere nel dettaglio come fai per recuperare il rame. Grazie
Hey bro. A faster way to get silver out of solution is boiling water and sea salt. It will be instant and you won't have to waste your copper. And to get the copper out of solution all you have to do is put steel pieces in a bucket and let it sit. And one more helpful hint take a piece of angle iron Anderson to the metal grate in your sandblaster booth and it will save your sandblaster Booth from being damaged like it is starting to happen on the back wall period because those booths aren't cheap either. Just some helpful hints to save you some time and money
thank you I appreciate it.
Witam witam i pozdrawiam serdecznie z Polski 🇵🇱👍👍👍
Good job 👊
Super Video!
Your Hammer Mill is great...I'm looking in germany for some mill live yours... without success😢
Can you send me a link whete you gut yours?
Thank you !
I post all link in description. Sometimes the venders change their products make sure its DF-40S 120v 2200watt 1-40kg/h model. It's a Chinese generic unbranded mill. They also all over the eBay, shipped from China. You would probably need 230v model for Germany.
Truth be known, you lost some gold, but not much. I've been doing this stuff for over 10 years. Most of what you threw in that machine had zero gold. With very meticulous separation I would expect maybe a point zero one MAX recovery from each board. Most of that would not come from the gold pins. Example: A few months ago I got my hands on 30 + lbs of clean, unused gold riser pins. My recovery was 13 grams. Less than 1/2 a gram from a pound of pins. You had some gold pins and a few IC chips on each board
👍
Bonsoir je peux avoir ça beaucoup hein
😲Even f your UA-cam channel doesn't succeed, I believe you will. Impressive. And you may have paid for your materials with copper recovery! I trust you saved your washes? You'll find some gold in there.
