Copper

Copper smelting, mainly consisting of:

  • Charge preparation including pelletizing and drying
  • Sulphate or dead or partial roasting
  • Smelting and production of copper matte or black copper in suitable smelting units of different types
  • Handling and smelting/converting slag including decopperization and granulation of slag
  • Converting of copper matte to blister copper including control systems and gas collecting hoods for PS converters
  • Anode production including fire refining and anode casting.

Hot gas handling systems for process gases including:

  • Waste heat recovery
  • Gas cooling by evaporative cooling or by heat exchange
  • Dedusting with cyclons, hotgas ESP’s and scrubbers
  • Specific converter off-gas systems
  • Control systems

Wet gas handling systems including:

  • Scrubbers
  • Washing towers
  • Indirect gas coolers – star coolers
