Abstract The aim of this work consisted of developing a flotation model based on industrial data from modern and large mechanical flotation cells (up to 300 m3). Using industrial data from different flotation plants a general model was develop considering the metallurgical performance, residence time distribution, and operational and hydrodynamic conditions. The model considers the behaviour of each cell in a flotation bank separately, using a distributed approach. The overall mineral recovery by true flotation, in terms of the collection and froth zone recoveries and the gangue entrainment into the concentrate, was calculated. The mineral feed characterization by particle size and liberation classes allowed the evaluation of the metallurgical performance along the flotation bank. This paper presents a new approach for flotation circuit modelling and simulation, which addresses the challenges for improving the froth behaviour by varying the cell design as well as the potential for circuit optimization.

浮选过程建模和模拟的新方法

摘要 这项工作的目的包括基于现代和大型机械浮选槽（高达 300 立方米）的工业数据开发浮选模型。使用来自不同浮选厂的工业数据，在考虑冶金性能、停留时间分布以及操作和流体动力学条件的情况下开发了一个通用模型。该模型使用分布式方法分别考虑浮选银行中每个单元的行为。根据收集和泡沫区回收率以及进入精矿的脉石夹带，计算了真浮选的总矿物回收率。通过粒度和释放等级对矿物进料进行表征，可以评估浮选堤沿线的冶金性能。
