ChatSep 03, · The metabisulfite will separate (precipitate) the g from the Aqua Regia solution (once the solution has had the Nitric neutralized with Urea), "dropping" the actual purified g into the mud like substance that will sink to the bottom.
ChatCheck out this video. I concentrated the leftover solution from the first g precipitation and added more Sodium Metabisulfite to precipitate more g and drop it from solution. I got a little bit more g. Not really enough to measure on my cheap scale, but some more. The remaining liquid still tests positive for dissolved precious metals.
