组合捕收剂在铋钼硫化矿浮选中的应用

Application of Combination Collector to the Flotation of Molybdenum Bismuth Sulphide Ore

在对某钨矿山铋钼硫化矿无氰浮选分离现场生产流程分析的基础上,以提高铋钼选矿技术经济指标为出发点,进行了组合捕收剂的选择、用量等一系列的试验。在钼浮选中,采用煤油35 g/t和丁基黄药80 g/t的组合用药实现了钼精矿品位38.64%,实际回收率58.67%的生产目标;在铋浮选中,采用乙硫氮263 g/t和丁基黄药87 g/t组合用药生产出品位10.51%,实际回收率34.96%的铋精矿,铋钼硫化矿尾矿含铋品位0.94%。两种药剂的组合作用提高了选矿技术经济指标,铋精矿品位提高了1.95%,铋尾矿品位降低了1.75%;铋回收率提高了10.31%,钼回收率提高了20.6%,取得了较好的效果,为企业创造了一定的经济价值。

Based on analyzing the on-site e cyanide-free bismuth and molybdenum flotation production process for Jiangxi tungsten sulfide ore, experiments on combination collector choice and dosages were performed to improve the technical and economic indicators of bismuth and molybdenum beneficiation. The application of combined collectors （Kerosene35 g/t, butyl xanthate 80 g/t, Diethyldithiocarbamate 263 g/t, butyl xanthate 87 g/t） to the flotation of Bismuth and molybdenum sulphide produced molybdenum Concentrate with Grade reaching 38.64% and actual recovery 58.67%, and bismuth concentrate with grade reaching 10.51%and actual recovery 34.96%. The combined effect of the two agents improved the beneficiation technical and economic indicators.
