Formation of zinc sulfide species during roasting of ZnO with pyrite ...
It was found that ZnS was initially generated at about 450 °C and then the reaction prevailed at about 600 °C. The generated FexS would dissolve into ZnS and then form (Zn, Fe)S compound in form of Fe2Zn3S5when temperature increased to about 750 °C. This obviously accelerated ZnS phase formation and growth.
