Research of the Low Grade Fluorite Flotation Orthogonal Test

Abstract:

The run-of-mine ore samples which have been used in the study were taken from a fluorite ore. The grade of fluorite was 28.65%. From the condition test, the optimal grinding fineness was-0.074mm accounted for 79.5%. The final optimal reagent system was A₁B₃C₃D₃E₃ with comprehensive consideration. That is, sodium carbonate was 2000 g/t, sodium silicate was 1000 g/t, aluminum sulfate was 200 g/t, sodium hexametaphosphate usage was 1000 g/t, oleic acid dosage for 2000 g/t. Through the closed-circuit test of flotation, the final index was the fluorite grade of the concentrate was 97.69% and the recovery was 48.07%.
