For Sale ~15lbs of gold plated pins.

182g mixed metal plated connector pin yield. Disolved in AR, dropped with paired copper/sulfamic acid. Refined with AR/SMB.

I've actually been trying all kinds of recovery, trying to find the most suitable.
The solid pins, I disolved base metals with nitric, the disolved foils in AR. That was very time consuming and used a lot of nitric for a small return.
The pogo barrels went into copper(2)chloride leach and took a month but was relatively hands free and then foils to AR.
I want to try straight AR digestion now and make a dirty drop which I'd then refine. Seems like that might be faster and use less nitric. Someone actually recently told me that you may be the guy to talk to about such a process. Have you tried this method?

Hey i am new and just read this post. I am wondering how this process would work with GF jewelry scrap. Everyone that has commented has been doing gold plated pins. Thanks for your time

Gold filled and plated are in essence the same product, gold filled is much thicker though and not usually 24K. Gold filled usually is karat gold of various karat and plated e-waste products such as what i process are plated with 24 karat.
I don't process karat gold or gold filled so I don't feel comfortable guiding you as to which process would be suitable. There is a ton of information here in the forum and in Hokes book of refining though and I would recommend that you read as much as you can.

Best of luck in your adventures!

For $100/lb, these would have to yield 2g/lb of gold or more to be worth it even to most hobbyists, given the cost of refining.

For hobbyists who simply enjoy the process, maybe they'd go for it at that price.

Just putting my two cents in ….sreetips did an iconic video where he bought 10 lbs of pins just like these for $1000 on eBay. May want to ask him what he yielded but at beginning of video I think he said he thought he would get an oz off that. Don’t hold me to that but that’s what I recall.

It's POSSIBLE to get an ounce from 10lbs pins... but there are a number of caveats. They must be old. They must be THIN, so there's less base metal to plating. And they must come from high-end equipment.

There are some ultra-high grade pins where 5+ grams per pound can be expected. But they're not typical finds in e-scrap.

You'll never get that much gold from modern-era pins.

I'm at just over one troy ounce and still have several more pounds left to process from this purchase.
