  • Gold Refining Methods Mineral Processing &

    Using Air to Refine Gold by Oxidizing The use of a blast of air on the surface of molten gold or silver is probably the oldest of the refining processes. The method appears to be described in the Book of Ezekiel, to which the date B.C. 593 is assigned, and the principle is the same as in cupellation, which was described by Diodorus Siculus about B.C. 200.
