为了解现代光学测量技术在细粒矿物浮选中的应用,在深入研究浮选理论的基础上,分析了以往研究浮选过程的测量方法,提出了近年来最为先进的流体力学光学测量技术PIV和高速动态显微摄像技术,利用其测量的高精度、高分辨率、无干扰等优势,可以实现对宏观、微观尺度的复原流场、矿化过程的测量。PIV可展现流场的流态,得到所需的各种指标、参数;高速动态显微摄像技术可直观观察到颗粒气泡在流场中运动、矿化过程。利用现代光学测量技术可深入研究流体动力学和选矿,实现流场稳定和最佳流态,也可研究强化矿化微观过程,最终实现浮选动力学的改进和分选指标的最优化。

In order to investigate the application of modern optical measurement technologies in fine mineral flotation,the previous measurement methods of flotation process were discussed based on the flotation theory.The most advanced PIV fluid mechanics optical measurement technology and high-speed dynamic microscopic camera technology which had the advantages of high precision,high resolution ratio and non-interference were introduced. The two advanced technologies could measure the recovery of flow field and mineralization process on macro and micro point.The PIV technology could show the flow pattern of flow field,various indicators,parameters.The high-speed dynamic microscopic camera technique could directly observe particles bubble motion in the flow field and the mineralization process.The modern optical measurement technologies were beneficial to stabilize flow field and optimize separation index.
