    2020-8-14 · Metallic silver can be dissolved from gold alloys of less than 30 percent gold by boiling with 30-percent-strength nitric acid in a process referred to as parting. Boiling with concentrated sulfuric acid to separate silver and gold is called affination. Both these processes are used on a commercial scale for separating silver and gold.

    2015-8-5 · explaining how to refine silver for silversmithing. This is the consequence of a rather subtle fact, namely that refining silver is identical to the cupellation of silver for assay, which in turn is identical to the parting of silver and lead in the lead reduction smelting process. The only difference between these three things is one of scale.
