    There are many thousands, probably millions of reactions that look
    good on paper but won't necessarily work in reality. There are also
    many ways to skin a cat or recover silver from silver nitrate. Some
    people have said do such and such rather than buying large quantities
    of hazardous nitric acid, but the person who asked the last question
    on this subject has said that he already has a large amount of silver
    already dissolved in nitric acid which has then been diluted with
    distilled water. He therefore doesn't need to buy any nitric acid.
    It's a no brainer really, just use the very simple adding copper
    metal displacement method. Sacrifice some cheap copper in an
    essentially safe (or much safer than other quoted methods) method to
    reclaim valuable silver metal. It's safe (relatively), it's fun and
    it's cheap (considering he already has it in nitric acid). He also
    has copper apparently.
