Extracting gold from gold filled Jewelry

[Rrosetl]

I am using distilled water i kept adding nitric acid between 50 and hundred ml at a time when it starting fissing at the top then thats when i would stop adding nitric and then i would let the fumes dissipate and add more. The reaction was working great.i just dont know if i should keep going or any recommendations moving forward the powder is not that bad and if its silver should that dissolve once i start the reaction again.

Wrong place, this is a Gold refining thread, you need to post this in "For Sale Trade and Wanted".
It is quite hard and illegal to buy Nitric in the UK unless you have the correct papers.
But try to post in the correct thread and you can get advice for how to do it.

Welcome by the way
