Display PCB Boards Gold Recovery FAILED EXPERIMENT

[@julianalcorso5703]

it is really great to see someone trying new things. Well done you! Just a thought, but after pilverising I qould have ashed everything and then, added HCL to get rid of tin. Then HNO3 to remove copper and base metals then Aqua Regia to dissolve gold......... Keep up your great work.

When copper gos for six dollars a pound soon ! Have fun scraping my friends

Well this video has answered my questions about computer boards. If you go back to around 7:43 in the video and look when your first dumping it you'll see all that gold stuff that's gold

Hola. Gracias por el vídeo Si eliminas los componentes con un cutter, impías con disolvente los restos de pegamento (de los Flex con la PCB) y procesas con HCl y H2O2. En 5 días lo tienes todo limpio. Yo solo proceso la tira de conexión con los flex y es 100% eficiente

Idd be worrying about any nano particulate that machine is blowing into the air off the PCBs in that first shredding machine getting under your toenails or in your lungs

[@timtoolman4125]

I looked at doing that a couple of years ago, with the electric wood chipper, I think it would work if you had a screen like what is on the hammer mill. The board has to bounce around instead of going straight through.

Sir it's possible to all copper out by nitric acid? Because i didn't understand about electric process please teach me

[@MetalScrapLab]

It will take a lot of nitric acid to get all that copper out. You need to research electrolysis and metal reactivity series to get copper via electricity.

@@MetalScrapLab can you give me any resources learn about it. I'm excited to learn

[@MetalScrapLab]

@@MetalScrapLab thanks a lot sir. ❤️❤️

[@timtoolman4125]

If you wash the copper off after removing from the bowl it will not oxidize as much, or at all.

[@torneandoelmundo]

What machine do you use to grind all the components?  

[@ayhamhafez285]

Is it copper nitrate electrolyte or copper sulphate?

[@MetalScrapLab]

Copper sulfate.

[@hosammohamed7107]

what is the name of the grinder

[@crazyanime348]

Company name of pulvarizer

[@MetalScrapLab]

It doesn't have a company name. It's a Chinese hammer mill sold by different merchants.

[@torneandoelmundo]

What is the name.of the hammer mill machines?

[@prospectorpete]

WHY COULDNT YOU MOP UP THE SPILL WITH PAPER TOWEL

[@MetalScrapLab]

I got frustrated and it would take a bit of napkins and more acids. It was just too much work for a little bit of gold. It's the process before the acids that excites me but chemistry is not so much. I might be replacing acids with cupelling.

[@Tanya-LeeLetourneau]

So you used the blue bowl totally wrong. I know I have one...

[@RobertSmith-xf6fh]

I want to hear not read

[@MichielBruijn]

Yeah you defenitely make mistakes. You have a higher risk of getting lung cancer.

[@MetalScrapLab]

Good point

[@youtube-marketer]

There is a solution, smoke regularly 😂
