Sulphation of cuprous and cupric oxide dusts and ...

Copper smelting with the Outokumpu flash smelting process generates significant amounts of SO2-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, and the sulphation of oxidic dust particles commences.
