Various types of waste materials containing zinc, obtained in steel industry, pose environmental concerns due to potential contamination of soil and water. This study investigates the alkaline leaching of low zinc content iron-bearing sludges to make them suitable for iron production by reducing zinc levels below 1%. An initial analysis of elemental, phase, and grain size composition alongside thermodynamic conditions of the leaching process was conducted. The research involved leaching tests performed at elevated temperatures (368 K for 60 min), which resulted in a significant zinc content reduction of about 66%. Additionally, long-duration leaching at ambient temperatures (298 K for 100 hours) led to a 60% decrease in zinc concentration to approximately 1.15-1.2% Zn. The findings underscore the effectiveness of alkaline leaching in facilitating zinc recovery from industrial waste, aligning with sustainable development goals while transforming waste into valuable iron-bearing material.
