Abstract: There is 1.0 Mt tailings resources with gold grade of 0.70 g/t in tailings pond of a gold plant.Tailings particle size was uneven，+150 μm accounted for 46.25%，-74 μm accounted for 26.50%.There was gold enrichment in crude and fine fraction.To make use of the secondly resources，recycle the gold，gold flotation experiment was carried out.Result showed that at grinding fineness of -74 μm 80%，with sulfuric acid as pH adjustment，copper sulfate as activator，and Y89 xanthate as collector，via two roughing-two cleaning-one scavenging and middling return to the flowsheet in turn process，gold concentrate with gold grade of 30.88 g/t and recovery of 59.11% was obtained.
