Gold plated boards Gold with ACID-PEROXIDE SOLUTION!

Ok so after some time i finish this recovery and video.This is board from that gprs modem and that pocket pc-s.I left it in AP solution almost a month ago and finaly i hawe result.Not the best,this is flash plating but you can use this simple method for hard plated goald board,also silver or palladium plated board to!See you soon freinds!

[@MrRonniejohnson]

Thanks for being real about this process and in the states right now gold is only 76$ a gram

[@rockman531]

Thank You for taking the time to teach us the process. I'll just continue to save the gold flashed boards - maybe one day it will be worthwhile. Take Care! Stay safe! Jim

[@davidleriche2489]

Low recovery but great video and information. Thank you my friend for sharing.

[@mdavidhandler]

it is amazing how little gold is used in modern flash plating. Boards from the 80's and earlier are thickly plated and provide a better ROI.

[@999DusanGoldrecovery]

One gram gold can cover one meter square with plating.

[@user-qz5jw6qi9y]

Ap solution will attack such thin layers of gold and will be dropped out of solution by the presence of tin and other base metals into micro particles that would be hardly filtered. I'm sure you'll get some gold from ap waste solution. Goodluck

[@dr.a006]

@@999DusanGoldrecovery It can be literally a few atoms thick! That’s amazing that it still looks gold that thin.

[@rogermontney7091]

I'm surprised you got a gram, honestly. Good job!👍 Those boards are flash plating with low karat gold. A lot of work for a little Au.

[@josephcormier5974]

All together those modems not to bad I don't think in the future it will be a judgment call I enjoyed your videos very much thank you five stars my friend

[@999DusanGoldrecovery]

On the end i am satisfated with modems, 70$ investment give me back almost half ounce of gold, lot vork there but Rome is not billd in a day heh.

[@BullProspecting]

I have a batch brewing right now! I have it on a slow simmer for best results! I have had it sitting for 2 weeks. It was a 5 pound batch. Great video bro!!

[@blacklabelonthebedrocks]

Hi Dusan, This was just a proof of concept, but a gram of gold is a gram of gold… Maybe there's some more in your waste solutions and filters. Many thanks for showing! Best regards from Germany!

[@999DusanGoldrecovery]

I leave it to settle on botom of barel and check, no more in it. I vill use this Ap again so acid dint go in a waste jet.

[@SilverScorpion]

Great video buddy!

[@hairymoobs]

Cool video

[@aussiescraphunter7808]

I would say a pretty fair result from what is just flashing, in Australia today that is almost $88, better than a poke in the eye with a sharp stick

[@Alex-kp3hr]

I would agree, not bad for just flash plating. regards from Melbourne

[@lukebowers536]

well done for getting a gram out of that, 999 Dusan, ive just started a batch of 200 pentium4 CPU's, the ones with the silver plated copper tops & gold spots instead of pins, i removed all the copper tops with a hot knife & took the MLCC's, i got 165 grams of palladium MLCC's & 1 kilo of copper, ime using 40% strength acetic acid with a just a dash of peroxide to start things off on the stripped fiber bases, i will let you know the yeald when done in a couple of days so you know if its worth the hassle, i dont expect a lot but i though it worth trying as acetic acid is very cheap here. Ile be happy if i get half a gram of gold, anything more is a bonus

[@australianscrape-waste7293]

They’re tin plated tops mate, if they were silver plated I’d be a happy man 😂

[@999DusanGoldrecovery]

Lot of cpu there. I do one smaller batch but i dint find silver there mate, onli tin plating on copper. Did you collect indium between caps and sillicon die?

[@lukebowers536]

@@999DusanGoldrecovery yes i scraped the indium from the inside of the copper tops to, i dont think i did a very good job thos as i only got 9.8 grams of indium, probably loads more on the copper tops still to scrape off. I did wonder if the silvery coating on the copper tops was something else. I grow copper crystals for fun here so will be interesting to see what is in the sludge from the electrolysis cell in a few months. ime just cleaning up the solutions now as you replied, does not look like i got much gold but its very clean spot foils from the CPU bases with no muck mixed in. Ile get a dry weight before i put them in aqua regia, even a tiny amount of gold using the method i did will be a small profit, the acetic acid i used is very cheap & the heat came from my home heating so a very efficient recovery. Ime not looking forward to doing all thos MLCC's tho. i always seem to make a mess of doing those.

[@lukebowers536]

@@999DusanGoldrecovery total gold yeald was poor at 0.7 grams of gold, lots of work for so little but the process was fun tho, ive learnt a lot about the makeup of modern chips, i scraped of a lot of lids a little better & scraped the back of the silicon chip dies, so now ive got 21.3 grams of indium in total, ile do the MLCC's tomorrow with grinding down & a hydrochloric boil & post the yeald of palladium & silver to, ive been told that the tiny 4 leg a side MLCC's on the pentium chips are high yealding for silver & palladium,

[@mariakoamigo7302]

Muchas gracias. Mucho trabajo para poco resultado. Para mi es el proceso más delicado, costoso en tiempo y ácidos y con menos resultado. Un saludo. Pd: yo lo hago igual, pero muy poco a poco, con más tiempo y casi no existe fibra verde. Muchas gracias de nuevo

[@kmstalk1211]

It’s working now for me 👍

É sempre bom saber antecipadamente a quantidade aproximada de ouro que podemos retirar de cada tipo de material. O video resolveu algumas das minhas dúvidas sobre a possibilidade de lucro na reciclagem de certas placas.

[@whateversmurfette]

perfect timing, i was just soaking some boards in lye to get the green junk off

[@999DusanGoldrecovery]

That is beter but more job for me and i notice that not make diference , only its cleaner.

[@KentuckyColonel]

I bought some H2O2 Hydrogen Peroxide 29% today to use in my lab.. curious to see how different concentrations react in the AP... Especially how reactive the oxidation is when I make another batch of Copper II Chloride

[@frantiseklaluch6605]

1g not bad, my guess was like 0,2 if anything, it is only flash gold, not plated...

[@niculanicolaeofficial9114]

Somtime exces Nitric will not show until you boil the soluțion before denoxing, even some gold will precipitate because is cold outside, the main gold is stil in soluțion. So my advice is to boil to 100C, denox again, and with just a small amount of SMB, precipitate again. Soluțion is not crystal clear si that is a sign of exces nitric or tin/lead/silver in soluțion. Good luck.

[@999DusanGoldrecovery]

Nice tip mate, i just add it in stockpot so i collect missed gold on the end. But this is a perfect step to do yes.

[@bazonis1gp]

👍👍👍

[@mr.g-sez]

did you cleaned the boards first with hcl, to remove the solder?

[@OnsloVest]

Cheers Dusan - there’s always next time…

[@jeffholmes1362]

Thanks for sharing, I have a question, if pins must be boiled in HCL to remove tin, we’re the boards cleaned of Tin first, or is the AP contaminated with Tin, so can’t be reused and would it effect your yield, if the boards were not completely cleaned of Tin first? Thanks

[@999DusanGoldrecovery]

In Ap tin stay in acid so dint contaminated gold fiols and flakes. But you can reused Ap again, just you need ad more fresh hcl and only copper pins, if yours pins is magnetic, they drop copper out from solution and make you big mess.

The used AP solution is a good broth for making soups and marinades, bon apatite!

[@floorskin1]

I have a bunch of similar boards and was wondering what to do with them.. Do you desolder them first?

[@whateversmurfette]

hydrochloric acid will dissolve the solder, but i collect it because it can be sold even if its just regular solder. since you end up with gold foils with this method you can just rinse them well in the end to keep the dissolved base metals out.

[@999DusanGoldrecovery]

You dont need to desolder em first, only if you collect tin.

[@cditzler6313]

oh well on the bright side you can keep reusing the AP so its not a total loss

[@999DusanGoldrecovery]

I use it lot more time, then i drop copper and that is a bonus, copper hase good price today.

[@jimmyhoneycutt1]

Dang man, might as well have used vinegar and salt maybe?..... On a different topic, I noticed from previous videos that you live in a rural area. I know you can't answer comments, but just by thumbs up or down........ do you hunt deer or rabbits or any wild game?

[@999DusanGoldrecovery]

Hahah no mate, im a fisherman but i dont enjoying in hunt. My freinds is hunters so they hunt rabbits and deers. I hawe here jackals and wild pigs to. No bears and wolwes thanx to God.

The gold mud looked like a lot more when it got dropped. It is what it is, I guess.

Gold is kind a flufi in drop, so reduce size in filter.

Is the Raw material and scrap are from Ukraine 🇺🇦 ????

[@dadacrvc5978]

First , boiling HCL to remove the solders ! Second , hydrogen peroxyd with citric acid and water...! Need 3 , 4 hours only and you got all gold foils and your solution stay clean and easier for filtration. You have too much residue with your method and it s too expensive.

[@HarryPotter-er8rt]

I don’t no what u are doing wrong but I get lot more gold from it then u do I use same amount

[@eyecare36]

Dusan could you do video using just AP to do this without AR? Can you use SMB to drop gold with just AP?

[@Chewy_GarageBandDad]

The answer is no. AP does not liquify the foils after they are removed from the board. You can try HCL + bleach...if you are trying to avoid Nitric, but, the HCL + Bleach is incredibly dangerous.
