Characterization of Galvanizing Flue Dust and Recycling Possibilities

Waste generation is a part of every technological process, including galvanizing. The presented paper deals with the characterization flue dust generated in process hot-dip galvanizing, and proposes possible methods for zinc recycling. released into atmosphere as white fume above bath, which caused by decomposition ammonium chloride present flux. This classified hazardous waste material particle size below 90 µm. In addition to iron compounds, it contains water vapor oils. elemental, phase, other characteristic are important subsequent selection suitable method processing material. At present, this not processed separately due its low production, approximately 0.3 kg per 1 tonne galvanized steel. proposed hydrometallurgical recycling enables on small scale recovery high-purity form metallic or oxide.
