摘　　要：针对某铅锌矿尾矿进行了降镁试验研究,采用反浮选法,以水玻璃为分散剂、油酸为捕收剂,浮选脉石矿物中的氧化镁,最终使尾矿中氧化镁含量低于1%,达到了尾矿烧结砖的要求。Demagging tests for the tailings from a lead-zinc ore were conducted.With water glass as the dispersant and oleic acid as the collector,a reverse flotation process was adopted to separate out the magnesium oxide in the gangue minerals,eventually resulting in the magnesium content in the tailings less than 1%,which meets the requirement of magnesium content in tailings for sintering bricks.
