Resistors on Circuit Boards for Ruthenium & precious metal recovery

Thick Film Resistors (TFR's) on scrap circuit boards contain an assortment of precious metals but mostly Ruthenium Oxide (RuO2)

Picking TFR's off circuit is a fiddly job but well worth the effort.
TFR's are an excellent way to stack ruthenium.
