| 摘 要： | 通过纯矿物浮选试验、Zeta电位测试、浊度测试、红外光谱测试以及Zn~(2+)溶液水解平衡计算,系统研究了Zn~(2+)对微细粒石英可浮性的影响及其作用机理。结果表明:微细粒石英纯矿物在油酸钠体系下基本不可浮,Zn~(2+)作用后的石英在pH=9~11时的浮选性能最佳。Zn~(2+)主要是以Zn(OH)_2沉淀的形式吸附于微细粒石英表面并促进其聚团,油酸根离子可能与石英表面Zn(OH)_2发生反应生成了油酸锌,从而促进了石英的上浮。

| Abstract: | Systematically studied the effect of zinc ions on floatability and mechanism of micro-fine quartz particle through pure mineral flotation experiment,Zeta potential measurement,turbidity test,infrared spectroscopy and solution chemistry of zinc ions calculation.The results show that the flotation recovery of quartz approximates to zero in the presence of sodium oleate,however,good floatability in pH range of 9 ～ 11 when zinc ions was added.Zinc ions forms in Zn(OH)2 sediment and absorbed on micro-fine quartz surface and promote its agglomeration,sodium oleate adsorption and form zinc oleate on the surface of quartz,thus promote the flotation behavior of quartz. |
