Non-ferrous metallurgy

In the field of non-ferrous metallurgy, GEA Bischoff focuses on cleaning gases that contain SO2 (sulfur dioxide). The efficient removal of impurities not only protects the acid plant equipment but also allows for the production of highly pure sulphuric acid, which later can be used in making fertilizers.

Roasters, smelting furnaces and converters for the production of zinc, lead, molybdenum and copper

• Dust removal from hot gases using cyclones and dry electrostatic precipitators
• Washing and cooling plants (quench towers, Venturi or radial flow scrubbers, packed cooling towers) including fluorine removal
• Separation of dust, heavy metals and sulphuric acid mist with wet electrostatic precipitators
• Separation of mercury in the calomel process
• Separation of sulphur dioxide from secondary off-gases.
