Abstract: The double wave fine mud shaking table was used in recycling tungsten and tin slime from Guangxi，the selected granularity was so fine that much tungsten-tin was lost in the tailings.In order to fully recycle tungsten and tin ore，in which main composition is wolframite and cassiterite，cyclone classification-HVC concentrator gravity-desulfurization and dearsenication by flotation,and then tungsten and tin mixed flotation process was applied.The mixed tungsten and tin concentrate with WO3 grade of 10.96% and Sn grade of 6.82%，the recovery of WO3 77.49% and the recovery of Sn 63.79% were obtained.Therefore，the technological schemes of sizing sorting and gravity concentration-flotation are efficient in second beneficiation of the tailings.
