Waste Paper Refining

[Dreamer]

It's been three years that I've been keeping anything (with few exception) that touches values (Paper towels, filters, anything incinerable) and when the bucket gets full, I incinerate to ash. My ash container is now full, so I gave it an extra thorough incineration and here is my refining plan that I hope to get comments and suggestions on:

1) Crush and screen the material
2) Remove any ferrous metal (with a magnet)
3) Dissolve base metals, Ag, Pd in nitric
- Filter solute to clear
- Drop the Pd with DMG
- Cement out the Ag
4) Process the undigested material with AR
5) Filter to clear and drop the Au with FeSO4
6) Cement out the Pt in the waste treatment stream (I don't expect much, so not worth the NH4Cl)
7) Incinerate the remaining undigested material and throw it in the crystalized AgCl bucket. I'm just accumulating it for now and will do a large pyroconversion on it in the future.

I know that I am going to have an appreciable amount of crystalized AgCl undigested because the starting material contained quite a bit of it. I'm worried it may cause some complications along the way.

My feed stock has been mostly GF, Karat and a whole bunch of silver along the way.

Your shared experience and comments would be greatly appreciated before I execute my plan.

Sreetips has done several recoveries of values from his filters. I'd check out his Youtube series on the subject, as they are highly detailed.

Did your bucket also contain test papers from stannous chloride testing?

I first put all paper filters in a beaker and fill it with warm water with some SMB in it to reduce any gold chloride.
I'm not sure if it will go up in smoke if you don't.
The rest sounds like a good plan to me.

Yes, they did.

Got a lot of respect for him. By the book kind of guy and unselfishly shares his journeys.
