    The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.

  • SMELTING SILVER

    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.
