However, due to the high content of zinc and other useful components found in it, EAF dust can also be considered as a secondary raw material for their recovery. In this paper, experimental investigations of the application of hydrometallurgical treatment of the EAF dust to zinc and cadmium recovery were carried out. The treatment was carried out in two phases: 1st phase - pretreatment, 2nd phase - leaching with sulfuric acid. The leaching rate of monitored elements in the second stage of treatment was examined depending on the concentration of H2SO4 and the duration of the process. The highest Zn leaching rate of 65% and Cd of 80% were achieved at a concentration of H2SO4 of 1.50 M in a time of 20 min, at ambient temperature, and a S:L ratio=1:4.enEAF dusthydrometallurgytreatmentconferenceObject
