Question in the expected yields of the green fiberglass CPUs.
I have just finished processing 72 of these CPUs and recovered .6 grams. Is this close to what others have recovered?
I removed the pins with HCl. Cleaned with water, dried them and had 145.6 grams of pins.
I then continued with slow heat and HCl in my crock pot. Cleaned the pins and dissolved in HCl + Cl, then cleaned with water and HCl washes.
If the yield that I got is close, it equates to .008333 gr. of gold per CPU, or about $.27 in value.
