Abstract: Through the magnetization treatment of sodium oleate solution, the changes of physicochemical properties such as pH value, absorbance, surface tension and electrical conductivity of the solution were investigated, and the influence of magnetization on the results of mineral flotation was studied. The test results shows that the pH value, absorbance and conductivity of the sodium oleate solution were increased by 0.53, 0.113 and 1.7 μS/cm respectively, after the sodium oleate solution was magnetized under the conditions of magnetic induction intensity of 320 mT and agnetization time of 10 min, the surface tension decreased 14.44 mN/mT; Zeta potential (absolute value) of calcite and fluorite decreased by 2.90 mV and 7.41 mV respectively; flotation recovery of calcite and fluorite increased by 19.77% and 12.81%, respectively; sodium oleate adsorption on calcite and fluorite increased 0.236 mg/g, 0.189 mg/g respectively.
