探讨了几种表面活性剂对脂肪酸类捕收剂W03的增效作用及其对胶磷矿浮选行为的影响.结果表明,阴离子型表面活性剂十二烷基苯磺酸钠(SDBS)对W03具有良好的增效作用,能明显改善胶磷矿的浮选特性.当矿浆温度为25~40℃时,混合使用W03和SDBS,粗选精矿品位和回收率比单独使用W03时分别提高1%和1%~4%.
The synergistic effects of several surfactants on the fatty acid collector W03 and its influence on the flotation behavior of the gelled phosphate rock were discussed. The results showed that the anionic surfactant sodium dodecylbenzenesulfonate (SDBS) had a good synergistic effect on W03 and could obviously improve the flotation characteristics of the phosphate rock. When the pulp temperature is 25 ~ 40 ℃, W03 and SDBS are used in combination, and the concentrate grade and recovery rate of crude concentrate are increased by 1% and 1% ~ 4% respectively when using W03 alone.
