| Abstract: | A low grade spodumene ore was seriously weathered and contained high amounts of mud, which located in Sichuan .These cause that the ore was very difficult for dressing. Beneficiation process was made to solve the problem .Spodumene was separated from gangue successfully by adjusting the dosage of NaOH ,Na2CO3 and CaCl2 when YOA was used as collector. And a flotation concentrate with the grade of 5.59%Li2O and the recovery rate of 85.24%Li2O was produced. |

| Keywords: | spodumene flotation dressing technology |
