Non-ferrous market

The global non-ferrous market is a fast growing and well performing market with high potential for the future. Non-ferrous metals include a number of different qualities and values. Beside non-ferrous metals like (e.g.) copper, zinc and lead in addition gold and silver are special goods with a special value. However, a growing non-ferrous process industry also carries negative developments. To follow trends and requirements emission control is one of the key-words for the future.

Gas cleaning units for process and environmental technology

Non Ferrous copper application

Environmental protection is not only a form of self-preservation of humanity but also a positive trend in the industry. GEA offers extensive technologies to protect the environment, not to inhabit the process chain and to create additional value that save money and meets the governmental requirements

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

  • 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
  • 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
