摘　　要：在不同pH条件下考察了FS对磷块岩纯矿物的影响。在磨矿细度-75μm占88.30%的条件下,讨论了FS、NA、油酸、油酸钠对实际矿石浮选的影响,结果表明:FS药剂在弱酸性介质中能够反浮选磷块岩,浮选效果优于其他3种,使用FS时,Al2O3质量分数可降低至5.18%。此外,采用ξ电位研究探讨了FS对磷块岩浮选作用的机理。Effect of FS reagent on the pure mineral of phosphate rock was explored under the condition of different pH values. Discussion about the impacts of FS,NA, oleic acid and oleic acid sodium on the flotation of real mineral with the grinding size fraction of - 75um taking up 88.30 % showed that FS reagent in the weak acid medium is capable of carrying out reverse flotation of phosphate rock with its effect being better than the other 3 types. Use of FS reagent may contribute to drop of Al2O3 content to 5. 18%. Moreover, mechanism of the effect of FS reagent on phosphate rock flotation is probed into by use of ξ Potential.
