Sažetak
Jarosite waste from Mitrovica Industrial Park, Kosovo, originating from zinc extraction industry, is considered hazardous due to the presence and the mobility of toxic metals that it contains. Its worldwide disposal in many open-dumps has become a major environmental concern. According to the chemical analysis (AAS and ICP- OES) of potentially toxic elements, the jarosite waste sample contain Zn, Pb, Cr, Cu, Zn, Ni, As and Cd which are extremely high in comparing with natural background. Cadmium mobility presents a serious environmental threat according to the Environmental Toxicity Tests. Furthermore, jarosite waste sample was characterized using X- ray powder diffraction (XRD) analysis, scanning electron microscopy with energy dispersive X-ray spectrometer (SEM/EDS) analysis, thermo gravimetric analysis (TG) / differential thermal analysis (DTA) as well as Raman and Fourier transform infrared (FTIR) spectroscopy analysis. The obtained results confirmed the presence of ammonium jarosite in the jarosite waste in Mitrovica Industrial Park. The presence of gypsum, franklinite, quartz, and barite was observed as well. It was indicated that the ammonium jarosite persists at 300 °C, along this line it show signs of decomposition at 400 °C and it is fully decomposed at 500 °C. TG and DTA analysis indicated that the decomposition of ammonium jarosite occurred in four consecutive stages. The applied modified BCR sequential extraction method and potential ecological risk index method confirmed that the mobility of Cd has major environmental impact. The order of potential ecological risk is Cd > Zn > Cu > Ni. The significant long-term beneficial effects to the jarosite waste stabilization are suggested together with best practice examples on the waste utilization in the building materials such as bricks, blocks, cement, tiles and composites and metal recovery.
