M33 - Conference paper at an international conference, printed in full

The paper investigated the stabilization process of the solid residue obtained after the hydrometallurgical treatment of EAF dust, which, due to elevated concentrations of heavy metals, shows toxic properties and does not meet the requirements for safe disposal. Stabilization was carried out by adding lime (5–10 wt.%) with the aim of immobilizing heavy metals. The results of the LP and TCLP tests showed that the efficiency of the stabilization process depends on the pH value of the environment and the amount of added lime. Under optimal stabilization conditions, specifically with the addition of 6 wt.% lime, effective immobilization of metals was achieved and the waste was classified as non-hazardous, enabling its safe disposal in a non-hazardous waste landfill.
