摘要: 对油酸钠溶液进行磁化处理,探究磁化对溶液的pH值、吸光度、表面张力和电导率等物化性质的变化,并研究磁化处理对矿物浮选结果的影响。试验结果表明:在磁感应强度320 mT、磁化时间10 min条件下,磁化处理油酸钠溶液后,溶液的pH值、吸光度和电导率较未磁化时分别提高了0.53、0.113和1.7 μS/cm,表面张力下降了14.44 mN/mT;方解石、萤石的Zeta电位绝对值较未磁化时分别降低了2.90 mV和7.41mV;方解石、萤石的浮选回收率较未磁化时分别提高了19.77%、12.81%;方解石、萤石表面的油酸钠吸附量较未磁化时分别增加了0.236 mg/g、0.189 mg/g。

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.
