In order to comprehensively recover valuable elements in tailings in Guangxi,the beneficia-tion test is carried out,and the reasonable beneficiation process for the recovery of each element is deter-mined.A gold-copper concentrate with gold grade of 5.47 g/t,gold recovery of 63.51%,copper grade of 1.52%and copper recovery of 78.76%is obtained by flotation process of one roughing,two cleaning and two scavenging with grinding fineness of-0.074 mm of 65%,pulp concentration of 30%,copper sulfate as acti-vator and butyl xanthate as collector.The iron concentrate with iron grade of 60.61%and iron recovery of 37.65%is obtained by low intensity magnetic separation of gold tailings.The tin concentrate with tin grade of 39.14%and tin recovery of 15.57%is obtained by shaking table gravity separation of iron tailings.The comprehensive recycling of the tailings resources is realized.
