Due to the high content of zinc in electric arc furnace (EAF) dust, despite its classification as a hazardous solid industrial waste, it can be used as a secondary raw material for its separation. After the detailed characterization of a representative sample of EAF dust, the two-step leaching process of EAF dust was investigated for the recovery of zinc and other components. The leaching process was carried out in two steps: in the pretreatment step (water leaching) and the sulfuric acid leaching step. With defined optimal process parameters the zinc leaching rate is 90.5 %. After the applied two-step leaching process of the EAF dust, the resulting leaching products were characterized, a kinetic analysis was performed, and the zinc leaching mechanism was determined.

This research was funded by the Ministry of Science, Technological Development and Innovation of the Republic of Serbia for financial support according to the contracts No. 451-03-33/2026-03/200052, 451-03-34/2026-03/200131 and 451-03-33/2026-03/200023.
