dc.description.abstractThe treatment of the EAF dust was carried out by applying the leaching process in two technological stages in order to selectively separate certain components from the EAF dust. In the first stage, a pre-treatment was performed to selectively remove water-soluble components from the original EAF dust sample, while in the second stage, zinc was selectively separated from the resulting solid residue by acid leaching. In the second stage of the leaching process, the influence of the acid leaching process time on the zinc, calcium and iron leaching rates were investigated. Selective zinc recovery from the EAF dust was achieved with the following optimal parameters of the acid leaching process: leaching reagent 1.0 M solution of H2SO4, ambient temperature, S:L ratio =1:4, time 10 min and stirring speed 500 rpm. The zinc leaching rate in the second leaching stage was 60.74%, while the Ca and Fe leaching rates were significantly lower and amounted to 12.18% and <0.01%, respectively.
