Help Support Gold Refining Forum:
Hi Alon,
you should really have studied a bit more before starting refining. And please, don't post in all caps, it's really hard to read.
What you are missing is denoxing. You need to get rid of the excess nitric acid or the gold will just redissolve while emitting a lot of red poisonous fumes. Read more about it in the library section.

Take it easy, as long as you don't throw anything away your gold is safe.
Put the beakers away in a safe spot with a loose cover, AR breaks down and builds up pressure if you keep it in a closed vessel.
Urea is no longer recommended for denoxing solutions, there are better methods. Use the search function and look for "denoxing" and read the library section.
And while you are at it, look up testing for gold and stannous, then you could answer that question yourself if the gold is in solution or not.

I would really like to help you out and Goran knows the answer very well.
The simple reason he is not telling you is that you might do something else and end up with an accident.
If you could show a picture that you are doing this in a fume hood I will tell you the answer.

When you find a word you don't understand, use the search function.ALON 1969 said:

If you have a hard time with the English you should call a friend or relative that can help you out. Google translate is also used by members which have problem with the English language.
I could probably tell you what to do but if you don't understand what is already written on the forum what guarantees that you understand me?
We will help you, but you need to put some work in yourself. With so many members on this forum we have no way of guiding everyone in detail.
If someone want's to do it on the other hand, it's up to them. I've helped some Swedish members on a one by one basis and I know it happens now and then that members invites other to show how it's done. Maybe some of our Israeli members could help you.
And if autumnwillow would like to help you that's okay by me.
But generally, the more you show that you made an effort to read and learn, the more likelihood that you will receive help.

Unfortunately the methods you will read will guide you through the proper way to recover the gold from the acid solution if you made it properly, as you did not do it properly it is difficult to just say do A,B, & C and all will be fine. It all depends on exactly what you did.
As Goran pointed out you have added too much nitric acid. You never said what material you started this process with so it is difficult to give you decent advice. Do you have a little acid, as in 100CC or liters of acid? It matters.
If you started with a scrap type, like karat gold, which is high in gold content, you will proceed differently than if you started with gold filled material.
So answer these 5 questions;
What material did you start with?
What was the weight you started with?
How much Hydrochloric Acid did you use?
How much Nitric Acid did you use?
Do you have a solution of stannous chloride to test your solution?
I realize you have a difficult time with English but this is a forum in which English is spoken. You have gotten yourself into trouble and now you are here asking for help. Normally members who behave this way are banned rather quickly. Since others have begun to assist you I think it best to let it continue forward. Don't tell us again about your language barrier, just answer the 5 questions asked and you will get answers on how to deal with this.

Hi Alon!
VERY IMPORTANT! The respirator you have will not protect you from the red nitric fumes! No respirator will. Make sure the wind is blowing from your left or right side so you don't get any fumes!

This can easily be solved, but not with your lack of knowledge and experience. Those max 5g gold can wait and they are not worth getting hurt. Without any experience chances are high that you will get a boil over and lose a lot of your values. Put it a safe place and spend some weeks of reading the forum. Maybe then you will decide to spend even more time only reading.
You have used about 360ml too much nitric. And you have very little gold in those one point three litres of liquid. If you try to fix this by a couple of answers you will let it boil over and/or you will not find your gold because neither you will know where it is nor what it looks like.
