Abstract: The sulfur content of a Zinc flotation tailings is 10.13%,the main sulfide is pyrrhotine and pyrite. The test research used magnetic separation-flotation joint flowsheet for sulfur recovery,by one rough and one cleaning floatation low intensity magnetic separation,got magnetic separation sulfur concentrate with S grade of 35.59%,recovery of 64.82% and flotation sulfur concentrate with S grade of 31.09%,recovery of 23.42%,merging the sulfur concentrate,the S grade is 34.27%, recovery is 88.24%.

Key words: Zinc flotation tailings, Pyrrhotine,Pyrite, Magnetic separation, Flotation
