Notice the abundance of neutralized nitric after. This is a dirty drop technique for those with cheap access to hno3. Good for mixed material. (Do not use on thick solid base metals with thin plating though it would be a waste) If you can dissolve all the base metals and pgms without adding more nitric, you can drop the gold with the tin still in solution. Then filter that first dirty drop to refine.
During gold recovery, the presence of tin (stannous) metal and excessive addition of SMB often cause metastannic acid-like crystals to accumulate at the bottom along with gold drops. This is a very annoying problem in gold recovery. However, I have already uploaded a video to solve this issue. You can understand the entire process by watching this video. ruclips.net/video/uG2rHRg-v5I/видео.htmlsi=sfsYhjYQf5eE5iNd
Which metal vessel will be suitable for heating sulfuric acid, Nitric acid. I am confused. I searched a lot of videos but not solved. love from INDIA❤❤❤
Nice. Thanks for precise smb mixing and showing the adding water part the 2nd time with the slow smb precipitation
You put most everything directly to aquaregia. When I try that I get metastannic acid to deal with. What a mess. Show us how to deal with that please.

I have the same problem it always wants to drop back out because of all the metal that has dissolves

Hello, I have never been able to melt platinum. What is its melting and boiling point?@@TrinityGoldRecovery
Perfect video 👏👏👏
Great explanation, congratulations. One question, what is SMB?
👏👏 interessante fazer as pinagens na água régia!!! Otimo resultado!
Where is that cotton from?
Medicine store.
Bonita pepi trini. Saludos para todos😊
Boa noite Trinity, queria aprender fazer aquela solução que vc faz pra testar o Gold. Vc tem algum vídeo ensinando? Obrigado
Use hydrochloric
acid and add tin solder to it heat thirty mins and filter them u have stannous chloride
