9 grams of gold powder...
From 386 and 486 CPUs.
This was a test to determine Pd and Pt content in old CPUs as I deal in PGMs only.
Nitric then aqua regia.
Sulfamic and dropped with SMB. Washed once.
Based on past performance, I estimate purity at 98+%.
I will split shipping anywhere in Canada and USA.
Western Union only.
