Abstract
Laterite nickel-smelting operations at Vozarci in the Republic of North Macedonia have produced large quantities of smelting waste, much of which has been dumped close to the smelter. As a part of our previous study (ĐORĐEVIĆ et al. 2024) we have mineralogically and chemically characterized various groups of slags from this area. To stimulate natural weathering conditions, we conducted long-term quiescent-flow leaching experiments. This case study refers to a real-life environmental scenario in which metallurgical slags originating from nickel processing were disposed of, leaving the slag boulders continuously exposed to rainwater during the rainy season. Our objective was to decipher the mobilization of contaminants from metal-bearing slags and to predict their potential environmental impact. The experimental conditions involved immersing the slags in the aqueous solutions adjusted to pH 2.9 and 4.8 for a period of 18 months.
