I had an accident while precipitating the gold on the final step. I accidentally spilled the solution which was unrecoverable. I was expecting less than 1 gram of gold.

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.

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

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

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

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.

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

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

@MetalScrapLab 4 месяца назад

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

Is it copper nitrate electrolyte or copper sulphate?

What machine do you use to grind all the components?

@hosammohamed7107 18 дней назад

what is the name of the grinder

@crazyanime348 4 месяца назад

Company name of pulvarizer

@MetalScrapLab 4 месяца назад

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

WHY COULDNT YOU MOP UP THE SPILL WITH PAPER TOWEL

@MetalScrapLab 4 месяца назад

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.
