| Abstract: | In this paper,dodecylamine was used as a raw material to synthesize a new cation collector by chemical modification.It was applied to a flotation test of processing mid-low grade siliceous-calcareous collophanite from Hubei,and good indices were obtained.By using double-reverse flotation process,single factor experiments,and orthogonal optimization,the grade of the ore was eventually improved from 17.45% to 28.5% in closed circuit with the P2O5 recovery of 80.2%. |
