To enhance flotation efficiency of fluorite ore, (E)-N-(2-hydroxyethyl) octadec-9-enamide was synthesized and then compounded with sodium oleate to prepare a novel collector CYHS-7. Then, an experiment on flotation of fluorite with CYHS-7 and sodium oleate as collectors was conducted, and the results demonstrate that an appropriate pH for flotation process is at 9, and the optimal dosages of CYHS-7 and sodium oleate in a closed-circuit test are 175 g/t and 350 g/t respectively. In a laboratory flotation test, the recovery of fluorite was increased by 9.15 percentage points with the dosage of CYHS-7 at half that of sodium oleate.
