One can see clearly the SO2 gas beeing dissolved and in turn pushing the gold out of solution.

@indeeditdoes hello just off the topic a little, im trying something i added electrochemistry to a dirty muriatic acid and peroxide solution and on one of the drywall screws there seems to be a build up of something like a brownish slim would that be copper or gold or a mix of everything?
-
The gold would stay out of solution as brwon or black powder

@indeeditdoes i added some SMB to a dark mix of muriatic acid and clorox and at the bottom its like a whit paste, what do you think this might be?

@LongBean420
Probably Cupper (I) Chloride...
Siphon the solution and cover the solids with fresh HCl, it should dissolve and produce a yellow solution.

so does this liquid actually produce real gold???

@Arnold34251
This liquid is actually gold, bot at it's elemental form, but in ionic complex with chlorine and hydrogen.

Will this also drop copper? What can you do if there is a lot of dissolved copper in the AR along with gold.

@gourp
yes, Cupper (I) Chloride tends to co precipitate along side gold.
Depends on the concntration and temp' of solution.
The CuCl can be dissolved later with HCl.
