typical yield from 10 Intel 486 CPUs?

I searched and couldn't find the gold yield for 486 CPUs. What would th etypical yield be for 10 intel 486 CPUs? or if it's easier a pound of 486 CPUs?
I saw mention of a spreadsheet showing yields, but couldn't find it :-(

oh, hello all! This is my first post to a very needed forum! It's great to finally find a bunch of people that are interested in refining gold from electronics. I have to thank "no_reserve" on eBay for one of his auctions mentioning this forum

I think 486 CPUs worth about 3$US each in gold content.

cool, I have a bunch of them

Is there a spreadsheet or a listing somewhere showing the typical yield from different electronic parts?

thanks!

The last time I processed a batch of 486 cpu's , I netted about 4.6 grams from 30 intel 486 dx2 . That would average out to about 4.50 apiece. Give or take at todays market price .
