As recently as a dozen or so years ago ferrous metallurgy was known as one of the biggest source of fluorine compound emissions to the atmosphere. Nevertheless production technology and raw material changes occurring in this industry cause continuous decreasing of their participation in the total fluorine emission. On the ground of investigations that have been carried out in the Katowice Steelworks (Poland) in the last few years, participation of particular technological processing in the water-soluble fluorine compound emissions (which are regarded as toxic) were presented in the paper, as well as a position of fuel combustion process (that take place in the CHP plant) in the emissions. Besides the fluorine partitioning in gaseous and solid (water-soluble and insoluble) compounds were characterized, as well as a problem of following reduction of fluorine emission from the biggest technological source – sintering process.
