Gold Recovery with Salt Vinegar Bleach peroxide - VIDEO
Here is all three parts of the video showing how the foils are lifted off the fingers. These videos are buried in another thread so I hope this is not
counted as a double post;
Part 1, using salt, vinegar and hydrogen peroxide to lift the foils from trimmed circuit card fingers.
https://youtu.be/ouYW_7-Njbs
Part 2, recovering the lifted foils for refining then dissolving the gold foils in salt and vinegar with bleach
https://youtu.be/TUxJ0YhATxM
Part 3, precipitating the pure gold with vitamin C

Useful precis of the process deltaH came up with.
It is a bit like Spam, as it could easily go in the main thread.
Much easier to Find like this though.

I didn't smell anything because it was in my fume hood. I'm curious though. Maybe I'll do it outside to see what kind of odor it produces.
