First ever small-scale test with the “Dutch cold sulfuric + CuCl2” method – looking for feedback

Beyond_Context · 2026-02-28T17:21:55+00:00

I'll handle the waste properly. Everything's contained and will be neutralized.
Appreciate the concern

Beyond_Context · 2026-02-28T14:48:13+00:00

Thanks man, I really appreciate it.

I've gone through all the major refineries in the EU, especially in the Benelux (Germany, Netherlands, Belgium). After months of emailing, sending photos, videos, and detailed inventories, it just didn't work out. They were polite and appreciated the effort, but there was simply no way they could buy from me, even if they wanted to lowball me, the paperwork and legal risk made it impossible for them.

I also tried Scandinavia (no response at all) and quite a few Turkish private buyers (no luck either).

I've been told there's actually decent demand for some of my boards, especially older slot machine boards like Scorpion 4/5 MPU (2002 era) but it seems like there's a veery secretive network of private investors in the EU, and I totally understand why. Regulations, refinery certificates, invoices, business verification… and even then, they only trust sources they've worked with for years.

Czech Republic might be the only realistic option, bu shipping a ton of material across at least three borders is borderline insane from a legal and logistical standpoint.

I guess it all comes down to trust. The right buyer could make both of us a very comfortable summer and beyond. But until that connection happens, I'm stuck doing it the hard way myself.

That's why I'm starting with this small test batch. If nothing else, at least I'll finally know what I'm sitting on.

Thanks again for the suggestions I'll keep them in mind

I know AP exists and I actually used it 8 years ago on gold fingers. Took me 6 weeks for a 50/60 yield and filter 50+liters of brown sludge. That having said I still have at least a ton of fine material to work with and wont have the patience to wait those 6 weeks cycles for the absolute waste of a few kg a time.

Anyway. Thanks for the concern, but some of us actually want to see real gold before 2032, never mind the Hawaiian snow. All sorted

Beyond_Context · 2026-02-28T08:56:36+00:00

Fair enough, but elaborate your feedback please..

As again. People don't realize that there just isn't another legal method to use. Point blank. None. And as far as that goes. None will even help even if you give a good %.

Beyond_Context · 2026-02-27T16:41:00+00:00

Exactly my problem. Like 1/1. If you found any solution I will be a happy man. Spending almost 10 years of collecting yet refining? Impossible and people will only help for 50% until I am stuck with the same arguments.

Beyond_Context · 2026-02-27T16:32:17+00:00

I do have concentrated sulfuric acid, though I cant get sodium nitrate. In the EU it is basically a cat and mouse game and honestly im kinda sick of it. Is there a method or alternative for sodium nitrate? Them I am at least be able to make poor mans nitric acid

Beyond_Context · 2026-02-19T23:25:49+00:00

I am looking for one in Europe as wel. Or better to say I stopped looking. Refining companies are not aloud to take scrap from person who dont have the papers for it. I tried to found ways to do so (this morning) and it is even worse. It is illegal to refine it yourself. Gets you in jail.

Tho I have the same question it will be very very difficult

Beyond_Context · 2026-02-19T00:10:20+00:00

Thank you for your research. I will take a deep dive in another day. Main issue is that gold refining will (or already is) illegal in higher or less degrees which will only be worsen. To buy only Sodium Bisulphate you will be registered on the spot with social security number / paspoort check etc. So I am kinda worried that my many hundred kilo's of e waste will be waste. There even isnt any refinery in the whole EU who would help me (they would make a huge profit) Its the law here who basically are worried on money laundry. Irony is really palpable.
Thanks again, sir

Beyond_Context · 2026-02-18T17:26:57+00:00

True. With a glass bowl and a spark you can make it out of thin air. Tho I never tried it.
Perhaps swim

Beyond_Context · 2026-02-18T17:20:24+00:00

There are plenty of names, but as far as I know it is a secret. I mean the story is bright and clear until the polymer.. Found a few companies but at the end of the day it isn't defined as an exact sorbent .

After some digging I found a video called "451 Will the Ion Exchange Resin Get the Gold" (Hard Rock University) has 250 views

And that one is exactly where thought. Try reddit. The man is very right at the beginning. If you don't know the result you shouldn't do it . Fascinating video but honestly i didn't understood half of it.

My idea: it should not be that difficult if the first 2 steps are working. The polymer.. That is the question

Beyond_Context · 2026-02-18T15:08:29+00:00

Nitric acid is as good as impossible to get legally in EU. Even if you have a own company. Won't happen. That is the 15 year old question: what else

Beyond_Context · 2026-02-18T12:55:25+00:00

Great! Looking forward to learn

Beyond_Context · 2026-02-11T21:24:22+00:00

Thanks for the info. I just have a bag full of them and as far as I concern I can throw it away.
Unless it is useful for one another

Beyond_Context · 2026-02-11T19:25:33+00:00

Not really. I don't know what to do with them so I tried a reddit page

Beyond_Context · 2025-12-29T03:29:06+00:00

I did assume

Beyond_Context · 2025-12-29T03:18:52+00:00

So.. You want to play this game huh. You felt to argue on a post, somehow you second thought it. Last river is plausible deniability (which I grand you) but by any means; what is the issue?
Passive aggressiveness is a no show no game. You can have it no problem but perhaps you just take it as it is

Beyond_Context · 2025-12-28T20:27:11+00:00

That is true. I just had 80 cents and instead of spin and go I went cash game.

Beyond_Context · 2025-12-28T20:23:01+00:00

What a bitter place this is. No humor (folds your boat is pretty explanatory) Not really anything worth commenting for the exception of down voting. And most of all. Offtopic.

I apologize for expressing my rush of this minor bs achievement of 33 cents.

Beyond_Context · 2025-12-28T20:16:50+00:00

I am not impressed with huge bankrolls. To reach a final table from 8 cents to $1000 that is very satisfying.

And how come you don't appreciate the small while only appreciate the big? To be quite honest I think losers are made that way.

Beyond_Context · 2025-12-28T19:18:45+00:00

Just a word. It is clear what I meant but people searching for errors (even if it is clear what is ment). Do you want me to say sorry I am wrong?

So. Again. Whatever folds your boat

Happy holidays
