2021-1-13 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.

1998-6-1 1.. IntroductionThe flash smelting process , developed by the Outokumpu company in Finland, is widely used throughout the world for copper production, accounting for more than 40% of global capacity for primary copper production.It is based on the utilisation of the heat of oxidation reactions of sulfidic concentrates. These reactions take place in a downwards flowing turbulent gas–solid ...

2013-2-7 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.

2004-4-1 Copper smelting with the Outokumpu flash smelting process generates significant amounts of SO 2-rich off-gas and flue dust. From the smelting unit, gases with a dust load are directed into a heat recovery boiler (also known as a waste heat boiler). In the radiation section temperature decreases, sulphates become thermodynamically stable,
