Dissolving paper coffee filters in AR

[Digibill]

Happy New Year everyone!

My question is regarding how many paper coffee filters can I expect to be dissolved in approximately 1 L of AR? Over the years ( yes, years) I've been saving paper coffee filters containing gold I've obtained using the AP process. Well, I'm finally ready to take that next step and I have obtained some nitric acid and SMB. My main concern is that there may be too much paper to be dissolved. I only purchased a liter of nitric (yes, I'm aware that will make more than one liter of AR) and that wasn't cheap. Do you guys think that I should just separate out the solids, brushing the gold off the filters into a single or couple of filters and then wash with HCL to remove any contaminants?

Thank you in advance for your time and consideration,

Bill

Use the search box, and look up incinerating filters.

Second that. Get a cheap frying pan in a second hand store and incinerate the filters. Kadriver, aka Sreetips have a video where he does it. But read some more posts on the forum too. I think Hoke calls it "the burn pile" but don't follow her advice about petrol on the filters. :wink:

... looks like Kadriver have two videos about filters. I don't remember exactly how he did it, so I have no comments on the videos at the moment.
