<p>[QUOTE="treylxapi47, post: 1609174, member: 41863"]I have refined silver myself on a small scale, and this ^ is the best answer ive seen so far. I used the Nitric Acid method and dissolved my coins and spoons to complete liquid, then used coffee filters and basic household items to recover the silver. For example I used pieces of copper scrap laying around the house to act as the catalyst to reform the pure silver crystals, then I lined household funnels with coffee filters and collected the 'gray' mud and rinsed until the water dripping out was clear instead of bright blue.</p><p><br /></p><p>Once my gray mud was 'cleaned' i let it dry on a piece of wax paper under a heat lamp for an hour our 2. Then I took my 'gray cake powder' AKA pure silver before its final form and used a potato and cinder block as my smelting block.</p><p><br /></p><p>I shallowed a small hole and then burnt the inside of the potato, to where i placed my powder and heated with a small propane blow torch from lowes. Once its heated you can see it melt and form together as silver, if you use real tiny amounts you can get nice almost perfectly round and smooth little silver shot. I didnt of course, so I ended up with larger clumps that didnt turn out quite as beautiful as I had hoped, but the experiment was still a huge success.</p><p><br /></p><p>I can probably locate the guide i used if anybody is interested, I had no chemistry or science skills prior and it worked out well for me. They are right though, the nitric acid is kind of expensive, and the process is time consuming. It was fun though, and if the world ever ends I will have the first hand experience and know how to refine silver using everyday items and methods. Not a bad skill to have i should think, I mean this method allows you to recover silver AND purify it from almost any form it would likely be in.[/QUOTE]</p><p><br /></p>
