I dissolved stone in hcl, naocl and h2o2 then drop that weird yeallow flakes. at first I thought is mica but i mean that mica cant drop after adding oxidizing agent. i want know what that may be. it is not souble in hcl and water and solution color is yeallow brown or green. that the same yeallow cristal in red solution have potassium bromide

Welcome to us.

Please stop what you are doing before you injure yourself or others.
Do you have an assay of the "stone"?
You never use acids on rocks or ore, and definitely not before having a thorough assay done.

Most likely your crystals are some kind of silica or oxide or other refractory mineral.

Now put your stuff away and start to study.
Here is for your studies:

We ask our new members to do 3 things.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: https://goldrefiningforum.com/phpBB3/viewtopic.php?f=54&t=19798
2. Then read the safety section of the forum: https://goldrefiningforum.com/forums/safety.47/
3. And then read about "Dealing with waste" in the forum: https://goldrefiningforum.com/threads/dealing-with-waste.10539/

I love the cushioned fume hood surface. Which interior fume hood designer do you use?
