Gold recovery from chips using AR, I’m sorry it was a typo

What do you think could be done with 15kg of pinned AMD CPU

Look like fiber but i honestly have no clue
Yes fiber and big heatsink.
You see a heatsink over fiber board with pins attached to fiber.
If you search the forum you will find lots of information.
Remove a heatsink to see whats underneath it, can't remember if there is a gold trace under them.

Cool thanks dude this is a crazy interesting chemistry
I don't like these.
Nice little gold legs.
Some mlcc's and gold tracings.
I scratched the traces under the mask and they are all copper.
The heatsink is attached using some rubber type material epoxied to board.
Remove them.
I would want to remove scratch off the mlcc's with a tool. Save them until you build up some poundage.
Maybe the rubber stuff would be okay in AP solution and filtered out afterwards.

If you check AP methods.
It will be HCl acid and the use of a bubbler.
Fish tank bubbler placed higher than the bucket you use. Tubing put under the 2 gallon bucket.
My bucket is a 5 gallon with a 2 gallon inside it and the 2 gallon, I drilled holes in it. Made it easier for cleanup and getting gold foils.
I tried diffusers stainless steel from amazon or ebay they won't work as they just disintegrate.
Can't remember if I added water to the HCl last time I did this, maybe only a little or just straight HCl.
But I added a small amount of peroxide to get it started.
Also I processed a hundred pounds of memory over several months and a few pounds of other boards.
The solution lasts a long time, so you can save for several jobs.
Because of the peroxide used there was some gold powder to be filtered out.
The process will take a week or 2 and recommended not to use peroxide and just allow the slow progression of HCl to work on the copper.
The air will oxidize the copper and HCl will start to dissolve it. The foils will start falling off.
EDIT ADD: you can downsize the buckets depending on how much material you plan to work with.
But..... its easy to get hooked on processing and refining. You will do it again!
This is to be done outdoors away from anything metal as HCl has a way to corrode metals.
Put a lid on bucket loosely, I put a brick on the lid and keep several feet away from metals.
