Technical grade — Sodium metabisulfite is commonly used to precipitate dissolved gold out of aqua regia and gold chloride solutions. Use about 1-1/2 tablespoons of sodium metabisulfite (SMB) for every ounce of dissolved scrap metal in solution. Good ventilation is critical as adding SMB to aqua regia produces corrosive vapors.
