超声波可使 PAMS 形成的钛铁矿、钒钛磁铁矿的混合絮团破坏,体系重新处于稳定的分散状态,因此可用多梯度弱磁选实现分离。超声波的解絮凝作用比分散剂的化学解絮凝作用更有效。俄歇电子能谱分析证明,超声渡不能从矿物表面上清洗已吸附的絮凝剂。它的解絮凝作用是由于空化作用剪断絮凝剂分子使其降解而破坏粒子间桥联作用的结果。
Ultrasound can destroy the mixed flocs of ilmenite and vanadium-titanium magnetite formed by PAMS, and the system is in a stable dispersion state again. Therefore, the separation can be achieved by multi-gradient weak magnetic separation. The effect of ultrasonic deflocculation is more effective than chemical deflocculation of dispersants. Auger electron spectroscopy proved that ultrasonic welding can not clean the adsorbed flocculant from the mineral surface. Its deflocculation is due to cavitation shear flocculant molecules to degrade and destroy the results of the inter-particle bridging.
