This is the metallurgy process in which air or oxygen-rich air is used as an oxidant to completely oxidize the iron and sulfur in copper matte in order to make blister copper. At present, the traditional Pierce-Smith (P-S) converting process is still the main process for copper matte converting.
Gold metallurgy is a technology for extracting gold and its compounds from gold ore, gold concentrate, or other gold-bearing materials. Gold is one of the earliest metals discovered and used, and its element symbol comes from the Latin aurum, with the original meaning "the glorious dawn".
