| 摘 要： | 采用单矿物浮选试验、Zeta电位测量、红外光谱、荧光探针以及溶液化学分析, 研究了油酸钠作用下红柱石和石英的浮选行为及作用机理。结果表明, 在油酸钠作用下红柱石在pH值6～7范围内具有较好的可浮性, 石英可浮性较差；Fe3+能够显著提高红柱石和石英的可浮性。红柱石和石英浮选行为差异的主要原因在于红柱石表面的Al3+可化学吸附油酸根, 石英难以吸附油酸根离子, 因此以油酸钠作捕收剂可实现红柱石和石英的浮选分离。Fe3+主要以氢氧化物沉淀形式吸附于红柱石和石英表面促进油酸根在矿物表面的吸附。

| Abstract: | Flotation behavior and mechanism of andalusite and quartz in the presence of sodium oleate were investigated by batch flotation tests, zeta-potential measurement, Fourier transform infrared spectroscopy analysis, fluorescent probe and solution chemistry analysis. Results show that andalusite possesses better flotability than quartz at pH 6~7 when sodium oleate is used as the collector. Fe3+ can remarkably improve the flotability of andalusite and quatz. The factors of chemisorption of oleate radicals onto andalusite with Al3+ on its surface and oleate being hardly adsorbed by quartz resulted in a difference in the flotability between andalusite and quartz. Therefore, a flotation separation of these two minerals can be realized by sodium oleate. Fe3+ is adsorbed on andalusite and quartz surface principally in the form of hydroxide precipitation, which can significantly improve the floatability of both minerals by promoting the adsorption of oleate thereon. |
