Abstract: Experiments on re-concentration of the pyrites tailings with the gravity process by shaking table and the flotation process were carried out.The results showed that sulfur concentrate grading at 46.41% was obtained by the gravity separation with shaking table，but 47.62% of recovery is low; Whereas，sulfur concentrate with S grade of 45.45% and recovery of 83.17% can be gotten by flotation with BS as collector and oil 2^# as foaming agent.
