Kennecott Smelter 53

The Smelter has 3 primary furnace operations, the Flash Smelting Furnace (FS), the Flash Concentraiting Furnace (FC) and the Anodes furnaces. Ore concentrate (roughly 27% copper content) is the primary feed material for the FS furnace wherein it is smelted into Matte Copper (68% to 70% copper) and S-Slag waste material. This matte copper becomes the primary feed material for the FC Furnace which further smelts it down to Blister copper (99.8% pure) and C-Slag waste material. From the FC furnace the molten blister copper is fed directly into Anodes Furnaces that adjust sulfur and oxygen after which it is cast into large anode plates and shipped to the refinery for final processing.
