VELASCO HURTADO, Carlos. Direct reduction of ZnS. Rev. Met. UTO [online]. 2015, n.37, pp. 23-31. ISSN 2078-5593.

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.
