Abstract：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.
