Does anyone know the precious metal content if any on these?

I was wondering what the precious metal content if any on these these are mainly from RAM sticks and motherboards and whatnot. Any information or a point in the right direction on a thread that's already addressing this issue would be greatly appreciated thank you.

Good morning,
they are Ball Grid Array I.C. chips (middle/high yield content of gold). The RAM IC have gold wires beneath the black epoxy " belt" in between the metallic balls, easy job to do mechanically with an engraver machine if you do not like the pyrolysis/incineration method.

So I'm finally going to be process these. I can't seem to find the best method to process these after incineration. Can someone please point me to the right thread? Or simply post some advice on how to process these?

Gold inside chips (black, flatpacks - not CPU)

Read the whole thread, some things change further down. As well as a PDF file of Pat's process.
