Flash Copper Smelting to matte has been a process improvement resulting in higher SO2 concentration. In the Outokumpu flash smelting process developed at Outokumpu Oy in Finland, the furnace charge is blown into the furnace through a specially designed burner with air preheated to approximately 850° C. The heat from the reactions …

اقرأ أكثرIn 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.
