A review of CFD modelling of flotation cells

This paper presents an overview of the literature concentrated on using computational fluid dynamics (CFD) for modeling froth flotation process. The physics of flotation cells are described and the equations that were used in CFD models are reviewed. The utility of using the CFD model is illustrated in this work through presenting examples of research efforts for simulating froth cells. First, a CFD model which provides a realistic approach to flotation kinetic within flotation cell is introduced, and then the usage of population balance equation to track the bubbles breakup and bubbles coalescence is presented. An example of the use of CFD for predicting the failure of a thin liquid film within froth zone is also presented. The paper concludes by highlighting a number of important aspects not covered in open literature.
