Cathode silver from the Metso Silver Electrorefining Cell is dried in the silver dryer and transported by an intermediate bin and screw conveyor to the casting machine’s induction furnace, where it is preheated to a suitable temperature for casting. After preheating, the silver is poured into a tundish, and then from the tundish into a mold on a casting wheel. Automated burners keep silver from forming undesired buildup. Cooling water is used on molds in order to efficiently solidify the silver bar. After solidifying, the silver bar is carefully ejected into a water-cooling bin and sent to the Metso Silver Bar Handling Robot for final processing.
