There will be a brown or black residue on the bottom. This is the gold. Rinse with clean water several times, carefully pouring it off to not lose any gold (after waiting LONG enough for ALL the gold to settle to the bottom, this could take a good while). It's a good idea to do a final rinse with ammonia, followed with a distilled water rinse.
