We crashed that piece of slag to fine powder panning again, magnet separation again (there is another quantity of iron (little))
Did the smelting again.
200g the powder
40g borax
20g Sodium bicarbonate
5g Potassium nitrates
1.5g copper welding rod
4g pure silver (powder)
Smelting for 3 hours, and we got this result (see the image) and see ( before nitric acid)
We took a piece of them and put it in a concentrate nitric acid, reacted for a minute and stopped left the piece black and green liquid. (See the image)
Cleaning it with fire and water (see the image after the nitric acid)
Any recommendations or suggestions, it would be highly appreciated.
