***,
Just takeing a shot in the dark here, I can't say as to the top photo. However, I would have to say from my experiences with e-scrap the bottom picture is a heat exchanger. As such, i believe the basemetal in it would be Aluminum???.
Also, I thought mono's contained gold and were rather easily identified as such as the leads coming out were usually gold plated.
Again, if I have mislead, I am sorry. Just seems to be what I can remeber from prior posts dealing with these mono's.
Good Luck,
Nick

Looked around a little bit,
The picture contains images of a few monolithic capacitors. They are label C3 C7 C10 C11 C12. I have personally cut a few apart for visual inspection for gold, and was disappointed. The articles I have read suggest that some mono's use Tantulum as the base metal. From the forum people have said Palladium is also a component in these monos. JustinNH and LazerSteve just posted a topic on the testing procedure.I have no idea why nor the value, though I have heard on the forum that Tantulum values can add up. Hope this helps, I'll be anxious to hear Steve's or Chris's reponse to your topic.

Palladium = roughly $200 a troy ounce.
Tantulum = $72-75 a pound
P.S. Sorry about picture size if it exceeded limits.

Here's a good thread to read:
SMD Identification
Steve
P.S.: The three contact black component in the last photo is a transistor or voltage regulator. Cross reference the numbers on the front to identify it.

Very good topic steve, I see in my own pictures where the Cx is right on the board 
I got serveral questions anwsered from that post, Thanks
Anyone that wants the answers to mono caps, that link steve posted has most of what you could ask somewhere in it..
I will answer my own question now: the ones outlined in red with A,B,C
are mono caps (dont forget to look for the Cx next to the part). The ones in Blue are not

Looking at image: IMG_5101.JPG, I do believe some of those are plated copper I save them all for a better study of the metal they are made of. They are very small to somewhat large. Several in power supplies as well.
