Look up SMB / sodium metabisulfite. It can be purchased on eBay for use
in dropping gold. Stump Out has sodium metabisulfite as an active ingredient.
Search the forum and you will find links to Stump Out. I have never used it.
My SMB has come off of eBay and it always has worked for me. 8)

When in doubt, cement it out.
It's always an option to cement all metal from solution and start over.

Being a rookie at all of this I’m sure all my procedures are suspect . After dissolving my scrap in HA and H2O2,filtering off, and redissolving the residue in AR, and filtering to a clear green liquid, I added SM to precipitate, got a reaction when adding, but my precipitate is white! What did I do wrong this time? Also, how would Zi get back to square 1? Thanks.

What was the scrap you were refining? Did you denox the solution before you added Smb?
