Weigh the silver and put it in one or more 5 gallon buckets. Add 150 ml nitric acid for every ounce of metal in the bucket (s). The acid will tend to react violently to the metal, bubbling and fuming. Make sure there is enough extra room in the bucket to accommodate the foaming (2-3 times, or more, the volume taken up by the silver).

Refining Silver and Gold Another Fearless Year

2010. 2. 24. The silversmith and the goldsmith start their work with impure silver and gold ore. Through the refining process they extract and mold the pure gold and silver by removing all of the impurities in the ore. This process involves fire and the close attention of the smith.
