Here is a photo of the precipitate mentioned earlier (top photo).
I've been so busy with other refining tasks that I have not had time to do anything with this.
But I am starting to see more PGMs coming through my shop.
The bottom photo; stannous tests taken from solutions that dissolved some jewelers filings and clippings.
Those orange test strips where taken AFTER the gold had been precipitated.
The test came from the green solution in the middle photo after the gold was precipitated with SMB.
