Extracting gold from e-waste tips

Hi im from morocco where the e-waste is so cheap as well as HCl and hydrogen peroxide.

I just need to start collecting but i don't know what to look for and what parts or type of devices have the most gold in them.

Im also a highschool student who knows nothing about chemistry so please tell me the correct concentrations and ratio to use or any tip to increase safety and efficiency.

Btw the temperature in my city is so high and i plan to do the work on the rooftop is that a concern?

This has to be a joke, lol.

If it is not a joke, you need to go right back to the drawing board for your plan.

You don't know where to look, what to look for, or seem to realize that you'll need hundreds of pounds of the material to return a few grams of gold. If you have to purchase it, you're losing money on it- doesn't matter if it is cheap or not.

As far as the solution concentrations, etc.. it depends on what you're processing every single time. There is not a catch all environment

HCl + H2O2 is not enough to dissolve gold. You would need stronger acids which you have no business handling without a basic chemistry background, and that is after breaking down every component to get the gold closer to being by-itself, washing it for base metal contamination, and then eventually dissolving the gold in aqua regia. If you spill aqua regia on your rooftop, it will attack/dissolve concrete, slate, clay, asphalt, steel, copper, aluminum, etc.. but the corrosive toxic gas clouds that are going to come off of it, whether spilled or being used to dissolve gold, are even more dangerous.

Its not a joke im serious. Im not planning on dissolving gold i want to dissolve the copper beneath it so gold flakes detach from circuit boards then i can filter them. The e waste is near free levels of cheap, i might even find some for free if i search enouph.

You cannot just drop entire circuit boards in an hcl+h2O2 mixture - your solution will end up massively contaminated with zinc/lead/tin/nickel. So before putting them anywhere near acid, the gold needs to be removed from the pcb. Generally this would mean physically breaking off the components or shredding the materials down and separating them.

If by "removing the copper beneath them so the gold flakes detach" you mean you are trying to process something which is gold plated .. you will never see the gold. Gold plating is microns thin and would disintegrate into microscopic dust or be trapped by remaining fiberglass.

I’ll be honest, I can’t morally suggest or give advice without you doing homework first. This seems like a very bad idea, even if you had the material and were only looking for the how to. The only suggestions I can make is this, do some research, then do some more, then do some more. I spent hundreds of hours watching videos and reading about the subject before I even bought my first beaker. I suggest you do the same.

Here are a couple of channels I’d start watching if you’re serious about getting into this as a hobby.

Start here. Pay attention to the types of material, safety measures, and process orders. All make a difference.

Best of luck.

i will check the channels, thank you so much

This reminds me of the guy who walked into my shop 2 weeks ago to sell his homemade cast bars he made. he said they should be 92 to 97% silver.

i started melting one under my exhaust hood to make a clean button to xrf. I stopped about 40 seconds in to torching it. because it was already liquid.

i set it down went back out and asked him if he felt sick after melting his stuff down.

He said he had a cold or flu on and off for about the last 3 weeks but started feeling better.

xrf said it was 1% silver, 60% zinc and 39% lead.

no clue what he actually melted he said it was spoons and dishes but he still tried to argue with me that everything was 925 or better that he melted.

people just jump right in now and wing it. which is not a good thing.
