Just a note: ruthenium ( $260 /oz ) is used in a lot of modern boards for resistors.
They are small, colored black and sometimes blue, and have numbers printed on the top.

just a question:
does removing the ruthenium & mlcc's lower the value of these boards when selling to buyers?
im assuming that since they are buying mostly for gold content, it shouldn't affect their value....am i correct?
To be honest, I really don't know about resistors. I know the removal of too many or all Tantalum caps on a higher-grade board will decrease its value. I only pull crystals and tantalum caps from low-grade boards that really have no value at all. On a few mid-grade boards, I leave them on as well. I pull off from most mid-grade because I will get more money in the long run from selling the components separately. On higher-grade boards, I don't mess with them. I leave it all on there to get as much weight as I can. I only pull junk off those kinds of boards. Junk like transformers, electrolytic caps, coils, etc. Doing that to some mid-grade boards will often increase their value, too.
Hope this helps!
From what I have seen, buyers are mostly worried about IC chips, monolithic ceramic capacitors, and yellow tantalum capacitors. I do not believe most folks even know about ruthenium oxide resistors.Quote:

You can probably say that we just learned about another value item that can be found on a circuit board.
Cheers for that mate ! :)
Precious metals recovery on all boards is measured in the tiniest fractions. That's the same with ruthenium as it is with gold, tantalum, platinum and all the rest. Depopulated boards are, in my experience, graded accordingly. At the refining level it would be noticed if it were common practice.
Keep an eye out for that Vibranium too. you can find it inside electronics that come from Wakanda I'm saving it up to make a shield .
