Display PCB Boards Gold Recovery | Recover Gold From Display Boards 

I think your videos are brilliant & you clearly have a great understanding of the chemistry your employing. If I may add a suggestion with ref to the huge volume you are using of Hcl (Hydrochloric Acid) and Hno3 ( Nitric Acid ). Your goal is to create Aqua regia which used on this material will digest everything metal on the boards gold included. Which is great. However approx 5ml of Aqua Regia (AR) will dissolve 1g of pure gold. My suggestion would be perhaps use a much lesser volume of AR and process your gold bearing materials through the lesser volume in batches. I would guess personally use just Hcl on its own and regular additions of HNo3 to the point there is no reaction and saturate the lesser solution with all the metals and then disguard the treated pcb’s to treat the next making full use of the acids. This will bring your processing cost right down and save on urea also. And working with less volume is safer for involved. I’m inspired I’ll have to make a video myself perhaps replicating yours with my method suggestion. Regards. Dave uk.

Good job. The biggest difficulty is finding cheap scrap metal, where I live. A hug.

You are a busy man! I know from experience. You had to take apart alot of LCD to get this amount! I like the older Dell LCD because they are much faster to take apart. I just got done taking apart all electronics from a 30 yard dumpster. It took me almost 2 weeks! Great Video bro!🏆🏆🏆

What about this? I know a guy whos making a pyrolysis chamber it can cook the boards into their raw components breaking down the plastics and polymers. Since its pyrolysis it will be oxygen free meaning most metals wont oxidize and besides that the heat point wont be enough to melt metal. Then the carbon ash can be removed easily and the remains can be put through various methods to separate them. For example gold panning could separate the gold and silver from lighter metals like aluminum steel or tin. I think you would have to do the finer methods of clean up and gold recovery but the equipments there from there purify the metals.

Good job 👏

Красиво, аккуратно, спасибо за труд и видео👍

There is a mistake or ulterior motive in the video! I extracted 1.35 grams gold from 4 kilos LCD board.

Great sir ..smart 🤓 work 👍

this is the video i wanted thank you

Hi sir I have some doubts after collecting the gold dust on cotton filter and that is any chances of gold in waste solution

Is there any gold or copper inside the skreen within the glas or plastic sheets? I have seen around the edge there is something

Currently gold is about approximately $70 per g. Don't know exactly how long this took you but if this was a job it would be far under minimum wage. Nonetheless, I appreciate the process and the chemistry is pretty cool.

Your videos very easily

Awesome video 🎉

As much as 1g of gold from 8kg of panels from monitors, a stunning result considering that it was necessary to disassemble probably over 100 such monitors and use so many liters of acids. I expected a better result. And what happens in this process to copper, silver, stannum, plumbum and other metals that aqua regia dissolved? None of them precipitate with the gold when sodium metabisulfite is added?

The gold I thought was solid on some pins out of old 1977 controller have turned redish brown. When I hit with sand paper there is gold under tarnish. How do I bring back gold color with chemicals??

Does the ic chips have gold in them ?

Siempre Grande, siempre adelante, maestro.

Спасибо.

Parabéns pelo conteúdo do vídeo guerreiro 💎⛏️🇧🇷

are we double the acid if we double the waste

Shor very Very good 👍

12L HCl 3L HNO3😮😮😮=1gr. Au. Кислоты дороже выходят. Если конечно халявные то можно всё и в бассейне делать😁. За труд 👍

Very Very nice 👌

Is Tang metabisulfite?

Im curious to know what your crucible is made out of. Do you make them yourself?

Привет дружище! По нашим ценам кислот ушло на 25-28$ больше чем вышло золота...но видео получилось 👍

Nice bro

Hi my friend .. good video bro 😁👍

Keep doing what you're doing, don't pay any mind to the ego driven morons. You see your vision, much love you're vision will become reality. Great video.

I sell this kind of stuff on ebay and let someone else recover the gold. I have about 50 computer lcd monitors I still need to take apart. My least favorite thing to scrap but I still do it.

This wouldn't be worth doing in Australia unfortunately with the price of our acids 😢 Great job though 👏 👌

Very Very good

in Indonesia the price per kg is 170,000 rupiah, if you only get 1.07 gram it's no profit

untuk pcb komputer apakah terkandung logam emas

No i mean .grinding and no wash After grinding i use my acids Do proplem in it ?or

Good instructional video but why such a low yield? I was thinking you might get 3g per kilo.

i do what you did in all your videos and come to the black powder. but every time i burn it. it does not turn into gold. its just become black aches. what is the wrong im doing?

Hi sir very nice video but only board 8kg with display

how do you clean conected elements from the PCB board without effort? Thanks

Very good work but average is very low

Sir, which smb powder is best? Food grade or industrial

Bro . The gold is 22 K.. ???? Or 24 K ??? 🤔🤔

I need more videos

Good bos

Olá amigo beleza eu estava vendo o seu trabalho achei interessante, uma pergunta por gentileza esse material que você queimou e de TV eu tenho um pouco dele. se moesse ficaria melhor para sair o ouro. existe moinho para este tipo de material onde encontra e a marca por gentileza grato. Inscrito 👍

Saiu pouco esse processo

Seems like there was a lot of gold left in solution.

That's like 63 dollars worth of gold. I would be interested to know how much it cost you for the HCL and the nitric. Seems like a big loss to me?

So its a rate of 1 to 8000?? dont you think you did something completly wrong?

The gold wire inside the IC chip is very fine! Wash the burnt ashes with water and remove them as much as possible. IC chips are made of epoxy plastic material! If you grind it without burning it, the fine metal wires will turn into powder and most of them will wash away with the water

i dont wanna get cancer for some penny

8 k × .5 g you lose much gold my frind ..

Ur wasting alot of acid man😮 and losing gold too😢

make a loss

Awerg very very low

Bad average

WHY ARE LOSERS... PRAISING THIS DISASTER ! Because it makes them feel like they're right at home !

Not worth the effort!

Seems like a low result. But thanks for putting in the effort and sharing! 🍺🫶🏼✌🏼
