A 500g bottle of Sodium Metabisulfite (NC-10319) is included in your Gold Recovery Kit.
Urea (NC-2620) in a 500g bottle.
To precipitate dissolved gold from aqua regia and gold chloride solutions, sodium metabisulfite is typically utilized. This is accomplished by combining it with a solution containing gold ions and heating the mixture, which causes the sodium metabisulfite to react with the gold ions and convert them to elemental gold, which is then precipitated out of the solution. Because it is more selective in precipitating gold on its own, sodium metabisulfite is a common choice in this method.

Sodium Metabisulfite is commonly employed in the extraction of gold from discarded computer electronics parts, together with Urea.

Urea, also known as carbamide. It is used in gold recovery techniques to neutralize excess nitric acid in aqua regia solutions. Urea interacts with nitric acid to produce nitrogen gas and water, lowering the acidity of the solution. It is critical to keep the solution from becoming excessively acidic, as this might cause the gold to oxidize and lose some of its value.
