Basic Instructions for Aqua Regia Refining Process

(For JSP #kit26, #kit26‐1, kit26‐2)

Important Notes:

• You will need concentrated hydrochloric and nitric acids (or substitutes). These acids are very corrosive, and the fumes they produce are toxic. When combined with metals, the fumes become highly corrosive.
• Refining must ideally be done outdoors. If working indoors, ensure the use of an exhaust hood.
• Refining gold in acid is safe when done under controlled conditions with proper training and knowledge.

Materials Needed:

• Pyrex beakers or heavy-gauge plastic buckets and a glass or plastic stirring rod
• Safety gear: goggles, rubber gloves, and a rubber apron
• Filtration equipment
• Hydrochloric or muriatic acid
• Nitric acid or nitric acid substitute
• Baking soda (sodium bicarbonate) acid neutralizer
• Urea
• Stannous chloride solution
• A gold precipitant
• Tap water and distilled water

Refining Instructions:

1. Prepare Your Gold:
Melt the gold and create small shot granules (not necessary for filigree or ladies' rings). Pour the shot into Pyrex or plastic containers. Use a container with 300 mL capacity per ounce of scrap gold. For example, 10 ounces of gold requires a 3-liter (3-quart) container.

2. Mix the Aqua Regia Solution:
For every ounce of gold to refine, combine:

• 30 mL Nitric Acid or 2–2.25 tablespoons nitric acid substitute
• 90 mL Hydrochloric Acid or 120 mL Muriatic Acid

Example: For 10 ounces of gold, mix 300 mL nitric acid (or substitute) with 900 mL hydrochloric acid (or 1200 mL muriatic acid).

3. Dissolve the Gold:

• Add the nitric acid or substitute to the container with the gold. Wait briefly.
• Add the hydrochloric or muriatic acid. The solution will heat up as it reacts with the metal. Fumes may be produced (less likely with substitutes).
• Allow the acid to work for at least one hour after the fumes stop.

4. Filter the Solution:
Pour the acid into a separate container through a filter funnel to remove particles. If particles are poured off, they may contaminate the gold.

5. Adjust the pH:
Add a pinch of urea to the solution. If it fizzes, add more until the fizzing stops.

6. Precipitate the Gold:

• Add 1 tablespoon of JSP® Precipitant per ounce of dissolved gold. The acid will turn muddy brown as pure gold particles form.
• Wait 30 minutes, then test for dissolved gold using JSP® Stannous Chloride solution. If the solution turns purple-black or purple-brown, add more precipitant and give it more time.

7. Rinse the Gold:
Once no gold is detected in the acid, pour it off carefully without disturbing the gold mud at the bottom. Rinse the gold mud 3–4 times with tap water, then with distilled water.

8. Dry and Melt the Gold:

• Dry the mud by placing the container on a hot plate (do not preheat the plate to avoid breaking the container).
• Once dry, wrap the gold powder in tissue paper, soak it in alcohol, and use a torch or crucible to melt the gold.

If done correctly, this process yields gold with a purity of 99.95% and minimal loss.
