Can’t let it go

Inherited lab equipment from a friend that died in Afghanistan who used to refine gold from computer scrap. I’ve been trying my hand at it and have run into trouble parting gold plate from skinny pogo pins. First batch I trimmed till my fingers couldn’t take it anymore and I parted with nitric n filtered it and it looks fine like any pics or videos I’ve seen. Second batch I just cut off silver looking pins and pulled the springs out bt some pieces of the silver looking pins remained. When I put nitric to it, got a lot of blue and when trying to filter it, was left with hard blue like crystal stuff, don’t know what it is? Could only filter part of it cuz filter was hard n jammed up. Took other half of it and filtered and got the same. So I took the second half and out nitric to it again and got mustard. Should I just throw the mustard and the blue crap away?
