Harold_V said:The real problem with this issue is that electrolytic parting of the vast majority of elements isn't within the capability of the home shop refiner. The problems with electrolyte contamination are difficult to overcome. The sole exception appears to be the parting of silver, and even that is troublesome, in particular when fed low grade silver. Contaminants quickly alter the behavior of the deposition, lowering quality in the bargain.
I don't think your efforts would be wasted----just not particularly handy for the vast majority of readers. Those of us that have experimented with electrolytic parting learned, long ago, that it's a waste of time.
Incidentally, I speak from experience. My failure came in attempting to part copper for the recovery of values. That is a losing proposition unless the copper is of high purity in the beginning.

It is not a good idea to put gold into an aqua regia solution with base metals.
I would give the powders a boil in water to wash some of the sulfate.
If there was not tin (or gold fill), you could remove base metals in nitric acid, before going to aqua regia.
If tin is involved, I would wash sulfates, dry, and incinerate the powders, cool, then boil in HCl, rinse with hot water, neutralize with dilute hydroxide and rinse salt well with water, dry, and incinerate again to remove traces of chlorides, before using the nitric acid.
