摘　　要：本文研究了矿粒与油相及气泡间静电相互作用力、范德华力、水化力及疏水力。根据扩展ＤＬＶＯ理论，计算了矿粒与油相及气泡间相互作用总势能曲线，讨论了油团聚回收细粒矿物、两液萃取分离细粒矿物及矿粒与气泡粘附脱附机理。This paper studies interacting forces of mineral particles with oils phase andgas bubbles,such as electrostatic force, van der Waal' s force,hydration and hydrophobicforce,According to the extended DLVO theory,total potential energy curves of the interac-tion of mineral particles with oil phaes and gas bubbles are calculated and mechanisms of re-covering fine minerals by oil agglomeration or liquid─liquid extraction and mineral particles, adhesion to or detachment from gas bubbles are discussed。
