摘要
首先从浮选动力学角度出发,以气泡和矿粒的相对碰撞速率与矿化率的关系为基点,研究分析了表观给矿速率与选矿指标间的关系;其次,以表观给矿速率为基础,建立起浮选柱直径计算的试验数学模型;接着,在确定浮选柱直径后,又以浮选时间为基础建立起浮选柱高度计算的试验数学模型;最后,以泡沫负载率为参照,对浮选柱直径进行校核计算。本文同时还指出了浮选柱试验选型的特点,不但要有合理的推理计算还要积累大量的生产实践数据来确定各个模型系数,以及对选型结果的处理原则。
Firstly,from the perspective of the flotation dynamics,and anchored in the relationship of the relative collision rate and mineralization rate between the bubble and of mineral particles,the relationship between apparent feeding rate and beneficiation index had been studied and analyzed. Secondly,the test mathematical model to calculate the diameter of the flotation column was established,which based on the apparent feeding rate. Then,the test mathematical model to calculate the height of the flotation column was established,which based on flotation time. Finally,a corroding to froth load rate,the diameter of flotation column had been checked. This article also points out the characteristics of the flotation column test selection,each model coefficients should be determined not only by a reasonable inference calculation but also a lot accumulation data of practice,as well as the deal principles of the selection results.
