Leaching of heavy metals (Zn, Pb, Cu, Ni and Cr) from hazardous waste originating from steel works (slag) has been investigated. This study aimed to understand the contaminant leaching behavior from monolithic waste materials over time and establish the cumulative leaching of elements per surface area of the waste material. The methodology employed tank tests to assess the impact of the duration of leachant contact with the waste on leachability. Dominant leaching processes were identified, with surface wash-off and dissolution being the primary modes of heavy metal release. Notably, chromium's release was found to be diffusion-controlled in a liquid of pH 7. Results indicated that the leaching levels of heavy metals were low in comparison to their concentrations, suggesting that longer testing durations could potentially facilitate the release of additional quantities of heavy metals. These findings highlight the environmental risks associated with metallurgical slag, underscoring the need for effective waste management strategies in the steel industry.
