Synergistic effect of FeS and ZnS content on the separation of lead and antimony for PbS–Sb2S3–ZnS–FeS quaternary system under water vapor atmosphere

Abstract

Synergistic effect of FeS and ZnS content on the separation of lead and antimony for PbS–Sb₂S₃–ZnS–FeS quaternary system under water vapor atmosphere has been studed in this paper. The results indicate that FeS can and ZnS can inhibit the volatilization of PbS. Inhibition effect of FeS is superior to that of ZnS to the volatilization of PbS. As to Sb₂S₃, FeS can inhibite the volatilization of Sb₂S₃, but ZnS can promote the volatilization of Sb₂S₃. Inhibition effect of FeS is superior to that of ZnS to the volatilization of Sb₂S₃.
