Abstract

Effect of ZnS on volatilization of Sb2S3 from PbS–Sb2S3–ZnS ternary system under water vapor atmosphere has not been reported in the literature. The mechanism of roasting process with steam in PbS–Sb2S3–ZnS system has been investigated in this paper. According to the fact that the calcine only consists of PbS and ZnS, it is indicated that the existence of ZnS can elevate the melting point of the PbS–Sb2S3–ZnS sample and make PbS and Sb2S3 more difficult to combine each other. As a result, the activity of Sb2S3 is increased and hence Sb2S3 will be easily volatilized into the vapor phase from the calcine. In conclusion, the ZnS in the sample can improve the Pb–Sb separation result.
