With the polymetallic tailings from Chenzhou of Hunan Province as the research object, an approach of macro volume and mass separation according to the composition of tailings was proposed for a comprehensive utilization. Firstly, magnetic separation was used to sort out iron-aluminum minerals, and then the non-magnetic minerals were processed to obtain calcium and silicon minerals by adopting a flotation process consisting of one stage of roughing, two stages of scavenging and seven stages of cleaning, with sodium oleate as the collector, sodium carbonate as the regulator, and the mixture of GLY-Ⅲ and sodium hexametaphosphate as the depressant. The as-obtained iron-aluminum minerals contain 40.17% garnet at a recovery of 94.08%. The obtained calcium mineral has a Ca grade of 58.00% at a recovery of 50.29%, with the content of fluorite therein reaching 76.47%, while the silicon mineral has a Si grade of 27.96% at a recovery exceeding 99%. These three products all meet the requirements for preparing building materials such as cementing materials and ceramic aggregates, providing new methods and ideas for high consumption of tailings.
