摘要:
这是一篇矿物加工工程领域的论文。本文通过纯矿物浮选实验研究了Fe2+和Fe3+在油酸阴离子捕收剂体系下对石英的浮选行为的影响，并采用红外光谱分析、原子力显微镜成像分析和Zeta电位测定分析等方法，进行了Fe3+活化石英的机理研究。纯矿物浮选实验结果表明，Fe3+的活化作用比Fe2+的强，在以Fe3+为活化离子的条件下，油酸钠的捕收作用比亚油酸钠强；红外光谱分析和原子力显微镜成像分析结果表明，油酸钠难以在未经活化的石英矿物表面产生有效吸附，但油酸钠可以有效吸附在经过Fe3+活化后的石英表面；Zeta电位分析结果表明，在pH值为6.0时，Fe3+活化后的石英表面的正电位达到较大值，且活化后的石英基本呈正电性。
Abstract:This is an essay in the field of mineral processing engineering. The effect of Fe2+ and Fe3+ on the flotation behavior of quartz in the oleic acid anionic collector system was studied by pure mineral flotation test, and the mechanism of Fe3+ activated quartz was studied by infrared spectroscopy, atomic force microscopy imaging analysis and Zeta potential measurement analysis. The results of pure mineral flotation test showed that the activation effect of Fe3+ was stronger than that of Fe2+, and the capture effect of sodium oleate was stronger than that of sodium linoleate under the condition of Fe3+ as the activation ion. The results of infrared spectroscopy and atomic force microscopy showed that sodium oleate could not effectively adsorb on the surface of unactivated quartz minerals, but could effectively adsorb on the surface of quartz activated by Fe3+. The results of Zeta potential analysis showed that the positive potential of quartz surface activated by Fe3+ reached the maximum at pH 6.0, and the activated quartz was basically positive.
