“…For the last few decades, the world's annual steel production has been steadily increasing, except for a small fluctuation in 2008-2009and 2015-2016(Gojić et al, 2022. World production of raw steel for countries that are subject to the World Steel Association had reached 1877.5 million tons in 2020 (Dutta, 2021).…”

Aim: To analyze the characteristic properties of dust and sludge from steel converters and to evaluate the perspectives of their reuse. Methodology: In order to evaluate the properties of samples, standard research designs were followed. Different methods such as titration, atomic absorption spectroscopy, inductively coupled plasma, optical emission spectrometry and combustion/fusion analyses were followed. Results: In a series of experiments, the percentage Fe and Fe oxides, calcium and zinc oxides as well as the amount of quartz were determined. A large amount of precious metals and materials in the study samples were recovered by suitable techniques. Instead of polluting the environment, the secondary products of steelmaking process can be reused. Interpretation: The work is important from the environmental point as it brings a complex view on the characteristic properties of steel industry dusts and sludges in the shape of physico-chemical and morphological properties, granulometric composition, and mineralogical analysis. This knowledge might bring better understanding of recycling perspectives of these items not only in the case of their pyrometallurgical processing. Key words: Dust, Recycling, Secondary raw materials, Sludge, Steel industry
