Lot of 241.6 gm Thick-film resistors, for Ruthenium (Ru) metal recovery

Description

These thick-film resistors are hand-picked off of mother boards, hard drive boards, etc., so very few miscellaneous materials included.
Thick-film resistors are reported to have ~40% Ru by weight, but this is not guaranteed.
Only those skilled in advanced precious metal recovery should consider this.
