You can either make money by refining your own gold at home or you can be a jeweler who refines gold in-house.If you take appropriate safety measures, there are many ways to refine gold on a small scale.The aqua regia method can be used to refine gold.
Step 1: You can put your gold jewelry, gold powder or gold Nugget inside of a crucible.
The melting of the material inside is mitigated by the fact that most crucibles are made ofGraphite.
Step 2: The crucible should be placed on a fireproof surface.
Step 3: Aim the torch at the gold.
When the gold is completely melted, aim the flame at it.
Step 4: Use tongs to pick up the crucible.
Step 5: Allow the gold to be separated into small pieces.
If you are refining small pieces of jewelry like rings, you can simply melt the piece without making shot particles.
Step 6: The container should be chosen.
If you want to refine an ounce of gold, you will need 300 liters of container capacity.Large plastic buckets or Pyrex Vision Ware pots can be used.
Step 7: You should wear protective gear.
You can protect your hands from acid by wearing rubber gloves.You should wear gloves when handling any of the chemicals in this article.An apron protects your clothing.You should wear goggles to protect your eyes.Wear a face mask to protect yourself from noxious fumes.
Step 8: The container should be placed outdoors in aventilated area.
The fumes from the aqua regia process are very dangerous.
Step 9: For every ounce of gold, put 30 liters of nitric acid in your container.
Allow the acid to react with gold for 30 minutes.
Step 10: For every ounce of gold, add 120 liters of hydrochloric acid or muriatic acid.
Allow the solution to sit until the acid fumes have dissipated.
Step 11: The acid should be put in a larger container.
Don't pour the particles out with the acid as they will ruin the gold.The acid should be green.If the color is not clear, you should pour it through a filter.
Step 12: Add 1 pound of urea to the water.
Continue heating the mixture.
Step 13: Slowly add the acid with the water/urea mixture.
As you add water and urea, the acid mixture will bubble.If you add the mixture slowly, the acid won't bubble out of the container.The nitric acid in your solution is not neutralized by the water/urea mixture.
Step 14: You can add a gold precipitant to a quart of boiling water.
You can add 1 ounce of precipitant to the gold you are refining.Don't put your face near the container's opening.The smell is strong.
Step 15: Slowly add the solution to the acid.
The muddy brown color is caused by the separation of the gold particles.Allow 30 minutes for the precipitant solution to work.
Step 16: The acid solution should be immersed in a stirring stick.
Step 17: The solution should be placed on the end of the paper towel.
Step 18: Place a drop of precious metal detection liquid on acid.
If the spot turns purple, you need to give the precipitant more time to work.
Step 19: As soon as the acid is clear of gold particles, put it into a container.
The mud collected at the bottom of the container should make the acid amber.The mud should not be poured with acid.The mud is gold.
Step 20: The tap water should be added to the mud in your container.
Allow the mud to settle by stirring the water.
Step 21: You poured the acid into the container by pouring water into it.
Step 22: The gold mud should be rinse 3 to 4 times with water.
Step 23: The gold should be washed with aqua ammonia.
White vapors will come off the gold mud.To avoid inhaling fumes, make sure to protect your eyes.
Step 24: Use distilled water to rinse the ammonia from the mud.
Step 25: The beaker has mud in it.
Remove all of the distilled water.
Step 26: Put your beaker on the hot plate.
The beaker should heat up gradually so that the thermal shock doesn't cause it to shatter.
Step 27: Continue heating the mud until it develops a consistency.
Step 28: The mud was put on paper towels.
The mud should be wrapped in the towels and soaked in alcohol.
Step 29: Take the mud and put it in a crucible.
If you performed the process correctly, the mud will be 99 percent pure.
Step 30: The gold should be poured into the ingot mold.
If you want, you can exchange it for cash at a precious metals dealer.
