Ok so I ran a few batches of gold filled, burned and processed my filters I have built up and processed nitric waste i been pouring over some gold colored chalices mark international silver co. in a collection pot and processed the other stock pots for any waste. Did several nitric dissolutions on all that for a single AR. I didn't get any silver out from the nitric solution even after a day of leaving copper in to cement. So ok I took all the filtration from the batches and filters and incinerated then into AR. Filtered solution added ice and sodium metabisulfite to percipitate the gold. I knew some gold was in solution from a stannous test. After a few hours or so I looked at it and these crystal formation are dropping out. (See photo) does anyone know what is dropping out so I know what to do with it? I.e. run thru nitric again to seperate and then thru AR to get gold out. Or if this is something other then silver or gold. I wouldn't think it's silver cause silver would have come out at the nitric phase of dissolution. I've just never had this reaction with metabisulfite to percipitate gold before.
This is at best a bit confusing since you are jumping a bit to and from with the Nitric and AR processes.
How much solution was testing positive?
How positive was it? Slight violet or almost black.
Did you ever take a picture of your stannous test?
The only thing sure is that the white comes from what you put in
or a result from the reaction with the metals in your lot.

If you did not get any Silver from the Copper cementing, there was probably not any Silver in there.
Did you ever test with salt or HCl?

It may be lead chloride which would have dropped out when you added the ice. Hopefully, you waited after the ice and filtered out the lead before adding the smb.
