Refining gold is something that you can easily do. But you have to take into account a number of things. You should put everything together before you start the process. You should also look for a work area that is large enough to accommodate a long table. Your work area should be properly ventilated. Realize that the smell can be suffocating so you might as well avoid working out in a closed space.
Here are some practical tips for you:
- Organize your supplies and materials. Your supply list should include nitric acid, hydrochloric (or muriatic) acid, urea, aqua ammonia, storm gold precipitant, detection liquid (specifically for precious metal), and water. On the other hand, your material list should contain a filter, a stirring rod (plastic or wood), a rubber apron, a pair of goggles, a pair of rubber gloves, and some containers.
- Transfer your gold in one of your containers. Note that your container should be able to hold at least 300 ml. That should be big enough to hold and refine an ounce of gold.
- Get your nitric acid. Measure about 30 ml. of it. Then, pour it into the container where you transferred your ounce of gold. Remember the ratio: 30 ml. (nitric acid) is to 1 oz. (gold). Allow the nitric acid to react with gold for at least half an hour. After that, pour it out of the container.
- Bring out your hydrochloric (or muriatic) acid. Set aside about 120 ml. of it. Add it into the container. The mixture is going to turn brown. It is also going to heat up (very hot). Then, don’t touch the gold for at least 24 hours.
- Transfer the mixture. Pour it into a new container. Make sure to filter it thoroughly. You should remove all the other particles present. They may contaminate your gold. Check out the acid. By this time, it should have turned into emerald green. It should be very clear, too. If the acid appears to be musty, cloudy, or unclear, filter your mixture again.
- Boil a quart of water. Add into it a pound of urea. Carefully pour the water and urea mixture into the container. The urea is going to adjust the acid’s pH level so expect to see some foam. By the way, don’t pour too quickly. The foam can cause the mixture to overflow. You may end up losing some gold.
- Boil another quart of water. This time add into it about ounce of storm precipitant. Afterwards, slowly pour the mixture into the container. Anticipate the overflow. The acid is going to look muddy as gold particles begin to form.
- After at least half an hour, use your detection liquid. Make sure that all the gold formations are accounted for.
Isn’t that neat? That’s how you can easily refine gold. Finish the process by pouring and filtering the last mixture into a new container. If want to see if there are some gold particles left, pour some aqua ammonia into the filtered mixture. Watch for the white vapors. They mean gold. Rinse the gold particles and allow them to air dry.
