川西某磷矿石P2O5品位为19.34%，主要脉石矿物为碳酸盐和硅酸盐类矿物。正浮选—
反浮选和单一反浮选工艺对比探索试验表明，采用单一反浮选工艺获得的磷精矿磷回收率远高于正
浮选—反浮选，且单一反浮选流程简单，操作性强。在此基础上进行的反浮选条件试验表明：以硫酸
为pH调整剂，磷酸为抑制剂，WF-01为捕收剂，经1粗2精2扫反浮选，可以获得产率为51.25%，P2O5
品位 30.67%，回收率为 81.28% 的磷精矿。试验结果可以为该地区普遍存在的同类型大量中低品位
磷矿石分选提供参考。
The P2O5 grade of a phosphate rock in Western Sichuan is 19.34%, and the main gangue
minerals are carbonate and silicate minerals. The comparative exploration test of direct flotation-reverse flo⁃
tation and single reverse flotation shows that the phosphorus recovery rate of phosphate concentrate obtained
by single reverse flotation process is much higher than that of direct flotation-reverse flotation, and the sin⁃
gle reverse flotation process is simple and operable. On this basis, the followed reverse flotation condition
test shows that: with sulfuric acid as pH regulator, phosphoric acid as inhibitor, WF-01 as collecting agent,
through one roughing two cleaning two scavenging reverse flotation, a phosphate concentrate with yield of
51.25%, P2O5 grade of 30.67% and recovery of 81.28% can be obtained. The test results can provide a refer⁃
ence for the separation of a large number of medium and low grade phosphate rocks of the same type in this
area.
