Abstract
Sulphation roasting offers the potential to simultaneously extract valuable metals from multi-metal sulphide minerals . In this study, the influences of roasting temperature and sodium sulphate addition on the sulphation of valuable metals were investigated under isothermal condition in a static air atmosphere. Additionally, the reaction mechanism during sulphation roasting process was characterized by thermogravimetry and differential scanning calorimetry (TG-DSC), X-ray diffraction (XRD) and scanning electronic microscopy (SEM). The results show that the optimum sulphation roasting temperature range is 600–700 °C. The leach extraction efficiencies of Ni, Co and Cu exceeded 60% when about 10 wt% sodium sulphate was added during roasting . The role of sodium sulphate as a sulphation promoter is attributed to an intermediate phase that acts as a reservoir of SO2.
