摘　　要：某钼尾矿为硫化钼和氧化钼的混合矿石,其氧化率高达86.09%。试验采用混合浮选流程,通过药剂的改良,克服了矿山水对浮选的不利影响,可以取得精矿品位6.53%,回收率77.17%的选别指标。The molybdenum ore tailings is a mixture of moly sulphide ore and molybdenum oxide ore,its oxidation ratio is up to 86.09%.The technological flowsheet of bulk flotation is adopted.Through improving the reagent combination,the adverse effects of mine water on the flotation process is overcame,thus the utilization ratio of the reclaimed water is obviously increased.As a result,a qualified molybdenum concentrate with the grade of 6.53% and the recovery of 77.17% is obtained.
