My first scrap recovery, can someone help me identify rubbish

SHORT INTRO:
Just getting into this for a hobby.
I wish to obtain some Tantalum, Halfnium, Platinum, Palladium, Gold, and Silver.
I'll be processing these myself - smelting/chemical extraction, mostly for the fun of it.

I've watched quite a few youtube videos and read a fair amount.
I've a strong understanding of chemistry, and smelting.
With an extreme focus on safety. I'll not be processing anything in the open air - fully closed and fumes scrubber.
My plan is to do this on a very tiny scale at first.

In the future I wish to process Gold ores from mining (others and my own). And so scrap recovery would just be a nice side complementary activity.
I know that there is a very small profit margin involved.



WHAT I'VE RECOVERED:
I found these vials of mercury just lying around in a box, now they are safely stored away for future play time. (I know how to handle mercury, I will not be shaking the vials).
Vials about 50mm x 10mm, probably 10 x 10mm of mercury in each.


Check out the video.


There are thin plates in the Rectifyer, silver?
That contact has what appear to be silver inside (I broke the glass that surrounded it), sorry for poor quality picture.


I've heard Elements contain Halfnium. This tiny one is from a Hair straightener (very old 1960's?).


A - old smoke detector, any of these plates of value, or should I just post that off for Americurium disposal (I don't want to play around with radioactive elements).
B - these anything?


That zenner worthy?
Suppose everything to left of Tantalum is just junk?


Just curious if that screwdriver bit from the potentiometer is graphite, appears to have graphite contacts inside also (just pink paint on top).


I've got lots of fun stuff to do while I await your replies, and I'll have more photo's of cool stuff when I return.

Two at top are air capacitors aluminum fins, radio tuners the bottom pair are diodes contain gallium.

No silver in any of those.

Not Gallium as someone said.
A - hole in white stuff from me nailing it to free the contacts.
B - white ring of something softish
C - appears to be hollow in photo, but is shiney thin layer of what appears to be silicon.

What is the part number, I'll google it for you.

Besides google a magnet will be your second best friend.

Also grab a copy of this publication from here. You Can Smelt Too, lots of information on how to chemically identify metals.

Your next consideration join the GOLD REFINING FORUM - GOLD REFINERS HELPING ONE ANOTHER

Once you've joined seek out a free copy of Hokes Refining Precious Metals, read this publication cover to cover before attempting to post on the gold forum anything beyond an introduction.

By having read Hokes publication this will arm you with the appropriate terminology to communicate with others on the forum. The gold forum membership do not suffer fools lightly

The only air gap capacitors I've ever come across were from WWII military radios,

The air gap caps were used to tune in radio frequency which has now become obsolete technology everything today uses digital tuners,

Crystal radios a totally different animal, then we have the razor blade radio shown in the sort youtube video below.

Various caps, the fins are aluminum.

Hey before you destroy these vintage transistors they appear to be prototypes from the 1950's, there are collectors out there who would probably die to own just one for their collection.

But then you already knew this because you've hot linked to a Russian site to the image used in your post above, do you have any more tricks up your sleeve.
