摘要：

The paper focuses on the mineral characteristics of silicate-calcareous phosphate from Yunnan province and researches flotation conditions and flowsheet of phosphate. Using double-reverse flotation process to reduce the silicon and MgO, and a phosphate concentrate with P2O5 grade of 30.13%, SiO2 grade of 11.12% and P2O5 recovery of 80.16% was obtained.
