There are some intriguing looking ones, but overall not too much. At least, I do not directly see any famous KMs or other good types. With a good bit of imagination maybe Bulgarian type MLCCs.. But not to be appreciated in the whole look. Majority are disc ones, fairly new, just bit of silver. Old square and disc ones tend to have slightly more Ag, Soviet red ceramic caps tend to have relatively good silver. But overall, not much Pd to be found here. You need to sort them out, as the low-end of these caps isn´t even worth processing in smaller scale (big disc ones, new, few g Ag/kg, very tedious process to get silver from tin alloys).
Sort out all MLCCs apart of just ceramic caps. Then you can throw them to the batch together with your previous batch of MLCCs.
PS: Asking about yield of some mixed components is not a good question (like your third post about yields of certain pile/boards). You cannot reliably build any "database" for yields of piles of mixed scrap. That just don´t work. You can burn yourself financially very very badly if you start taking decisions upon some guesstimate numbers out of somebody´s else assumptions. This is how you won´t build sucessfull operation.
