Zinc Dross Distilling Furnace

Zinc Dross Distilling Furnace

Optimal Zinc Recovery

Zinc dross distilling furnace


Every galvanizing plant produces dross. Molten zinc dissolves iron, for example, from workpieces that are hot-dip galvanized, from the wall of the galvanizing kettle or from flux. It must be regularly removed out of the zinc bath.


The zinc dross distillation furnace recovers 85-88% of the zinc bound in the dross with a purity of 99.9%. The furnace brings the zinc dross to evaporation temperature. The zinc is then condensed in the retort outside the furnace.


  • Improved quality, the galvanized surface is free of zinc dross spots
  • Permanently optimum immersion depth in the galvanizing kettle
  • Long kettle service life without overheating the kettle wall
  • Excellent economy, especially with high zinc prices
  • Environmental protection through recycling
