Non-ferrous

Environmental protection is not only a form of self-preservation of humanity but also a positive trend in the industry. 

GEA is a reliable partner for gas cleaning solutions in nearly all areas of non-ferrous production. To ensure the air pollution control, gas cleaning systems are essential components in the process chain. Focusing on cleaning SO₂-based gases in the process of sulphuric acid, covers roasters, smelting furnaces and converters for various non-ferrous products including:

• Copper
• Zinc
• Lead
• Molybdenum

Environmental solutions in you process chain might look for example as follows:

Zinc, pyrite and gold roasting smelting furnaces and converters for copper production

• Dust removal from hot gases using cyclones and dry electrostatic precipitators
• Washing and cooling plants (quenching 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

Rotary kilns

• Fine dust removal and separation of sulphuric acid mist using wet electrostatic precipitators
• Separation of sulphur dioxide using wet and dry procedures on the basis of limestone and caustic soda
