Effects of roasting parameters on the sulfidation behavior of ZnO at different temperatures: (a) sulfur dosage (carbon dosage was fixed at 8 wt.%), (b) Fe2O3 dosage (sulfur and carbon dosage were fixed at 60 wt.% and 8 wt.%, respectively), and (c) carbon dosage (sulfur dosage were fixed at 60 wt.%).
