This is simular to the means that I want to dissolve my US Nickles in the future. I did so in the past and it proceeded much quicker then just using H₂SO₄. I used HCl + 35% H₂O₂ before and the dissolving was obvious right away. The addition of peroxide to almost any acid increases its effectivness alot because it allows oxidation of the metal prior to its conversion to the salt.

I am considering just placing a roll of US Nickles into an electrochemical cell in an acidic media and using that to dissolve them in relativly short order since this would eliminate the need for the added expense of H₂O₂ which is a huge factor when extracting Ni from coins.


I think for Lead acetate you would be better to generate Litharge and add that to Acetic acid then attempt to dissolve it all in one pot. I tryed adding semi dilute peracetic acid(same concenrations used for isosafrole oxidation) to Pb scapes but the dissolution was slow at best leaving a white residue on completion.
