Disclaimer: I'm still reading Hokes and going through the slightly labyrinthian sub-forums, so I realize I might be way off here, but a thought has occurred to me.
My situation is that I have fairly limited access to Nitric, not loads of space to store scrap and a small but steady stream of scrap coming my way (for now).
The bulk of my gold-bearing scrap after depopulating and sorting breaks down into flatpacks, contacts with pins, trimmed fingers and loose pins. I'm saving cpu's, mlcc's and tantalum caps until I have more volume.
I do have access to HCL, peroxide and pure CuCl2 from leftover chemicals.
My thought is as follows: Flatpacks get incinerated, washed and put to AR, simple enough if Nitric is not a problem. Pins get sorted into magnetic and non-magnetic and processed in AP, though the leftovers from the magnetic ones is waste. For contacts I have still to find a good consensus...
What if, considering that HCL, H2O2 and CuCl2 are easy to come by, I set up a batch-based system rather than a continuous one. Then I could mix a batch of 20% HCL, add some CuCl2-solution, a dash of H2O2 and start up the aquarium bubbles and drop my fingers in. While those are cooking, I incinerate my plugs and flatpacks en masse and wash through the ashes to recover my pins and bonding wire, combine with my pins, magnetic or not, and run these through the AP once the fingers are done.
That would leave me with lots of gold foils, some debris from the incinerated stuff and a bucket full of spent AP ready for copper cementing and further waste treatment.
And before you yell at me, this is of course far from ideal and somewhat wasteful, but then again, it makes the process a bit more streamlined for batch processing rather than continuous recovery/refining.
Disregarding the obvious objections about not-so-ideal treatment of the scrap, time spent vs yield and other perfectly reasonable counter arguments; would this kind of set up work at all?
