    Flash smelting (Finnish: Liekkisulatus, literally "flame-smelting") is a smelting process for sulfur-containing ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production. A second flash smelting system was developed by the International Nickel Company ('INCO') and has a different concentrate feed design compared to the Outokumpu flash furnace. The Inco flash furnace ha

    In Copper Flash Smelting, flue dust can cause severe problems in the gas handling system, which typically consists of a heat recovery boiler and electrostatic precipitator. If the process is not operated properly, the flue dust may form accretions on the boiler wall, reducing boiler heat transfer and subjecting the surfaces to corrosion.
