I dont think the loss issues are so much from open burning, it's from the AgCl. It drags your Au up the stack with the thick white smoke.
I have saved filters for a long time, but I'm not sure if I should start out by boiling them in NaOH in hopes of converting some of that AgCl to Ag2O, or if I should tumble them in sodium thiosulfate. EIther way.
Even for polishings lots that I have already acid processed. I know there is still gold in it, I just don't know how much, and any of the standard processing methods will send some of that gold up the chimney. Just not sure if it's worth trying to avoid, because I'm not sure what the payout is.
