摘要
从微粒间的界面相互作用这一角度，探讨了经油酸钠作用后微粒赤铁矿的疏水凝聚行为，从而从一个重要方面揭示了赤铁矿油酸钠体系的浮选机理。并证明了经药剂作用后的疏水矿粒间的凝聚行为只能用扩展的ＤＬＶＯ理论来描述，而用经典的ＤＬＶＯ理论来描述存在较大的局限性。
Hydrophobic aggregation of extremelyfine hematite occurs by the influence of sodium oleate. From point of view of interfacial actions between extremelyfine particles, the paper discusses the hydrophobic aggregation behaviour, thereby revealing flotation mechanism of the hematitesodium oleate system. The authors have confirmed that the aggregation behaviour of hydrophobic mineral particles can be explained only by extended DLVO theory, instead of classical DLVO theory. This is because the latter has greater limitations in description of the aggregation behaviour.
