Abstract It's presented a thermodynamic study to assess the possibility of producing metallic zinc by direct reduction of concentrates of ZnS, whose main impurity are iron sulfides. The equilibriums in the Fe-S-O and Zn-Fe-S-O systems at the temperature of 1,250 °C are shown, and from these, the thermodynamic conditions under which the process can be developed are presented.
