    The use of ammonium sulfate as an inhibitor of dioxin synthesis in iron ore sintering process
    (Towarzystwo Chemii i Inżynierii Ekologicznej (TChiIE), 2014) Łechtańska, Patrycja; Wielgosiński, Grzegorz
    The main air pollutants in the sintering process of iron ore are polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans (PCDD/Fs) and harmful dust. Ore sintering on sinter strands is one of the first technology steps in the ironworks. It is a process in which iron ore is crushed, subjected to annealing and mixed with appropriate additives, and then sintered in order to produce sinter which is the main component of iron in the blast furnace process. PCDD/Fs emissions were measured and the addition of ammonium sulfate as an inhibitor of the synthesis of dioxins in the sintering process of iron ore was studied.
