作用于复杂硫化矿石浮选槽的脉冲导致矿浆中气泡振动 ,增强气泡与颗粒的碰撞 ,颗粒与气泡之间的液膜变薄和破坏降低了能量 ,结果颗粒与气泡粘附速率增大 ;此外 ,气泡表面机械振动有效地脱除了夹裹的亲水颗粒 ,微弱粘附的聚集体形成泡沫表面。泡沫影像分析表明 ,气泡振动形成的 The pulse acting on the complex sulphide ore flotation cell causes the bubble in the slurry to vibrate, which enhances the collision of the bubble with the particle. The thinning and destruction of the liquid film between the particle and the bubble reduces the energy, and as a result the particle and bubble adhesion rate increases. In addition The mechanical vibration of the bubble surface effectively removes the entrapped hydrophilic particles and the weakly adherent aggregates form the foam surface. Foam image analysis shows that bubbles are formed by vibration
