Abstract: In order to realize the efficient and comprehensive utilization of zinc and sulfur removal products from iron concentrate in the concentrator of Anhui Lujiang Longqiao Mining Co.，Ltd.，based on the study of mineral properties，the comprehensive recovery of zinc and sulfur by flotation process was carried out. The test results show that the zinc and sulfur removal products of the iron concentrate are first grinded and removed reagent，and then the flotation process of zinc and sulfur is adopted. The pH value of the pulp is adjusted by adding lime. The mixture of butyl xanthate and ethyl xanthate（1∶1）is used as collector，and 2# oil is used as foaming agent. After one roughing，two cleaning and two scavenging processes，qualified zinc concentrate and high grade sulfur concentrate are obtained，and satisfactory test indexes are obtained. The purpose of comprehensive recovery of zinc and sulfur is achieved，and the recovery and utilization of re⁃ sources is realized.
