Just my 2 cents worth, but to add to the others if it helps...
1st pic... the yellow ceramic capacitors... I have heard that they can contain silver, but not always or if they do, not in the volume as those silver-mica "dogbone" capacitors already mentioned by others. I myself am saving those for possible "why not" processing some time in the future when bored (once I'm experienced more with pyrolyzing) just to see what I may get out of a big hoarded stash of them lol
2nd pic... center black tiny item with 3 crooked legs... one of many types of transistors that, like ICs, can contain gold bonding wires and usually processed with IC's. Others may have more experience from actually processing them as to whether or not the average yield is even worth it or not to save them.
Also 2nd pic... center-bottom slime green color resistor... I not too long ago saw elsewhere where those types of ceramic resistors can sometimes have gold plated ends on the inside... but again... not always.
3rd pic... from best I can tell looking into the bags, looks as if you might have a couple more of those possible tantalum capacitors like the last picture, but hard to say for sure what all else you might have in the bags that may not be sampled out like the pieces on the floor.
