The flash flotation cell that is the subject of this work is situated within the grinding circuit and receives a portion of the cyclone underflow stream as its feed. To allow the reader to understand how this cell interacts with the surrounding equipment, a process flow schematic is provided in Fig. 3.
The Eulerian–Eulerian formulation is used to perform numerical simulations of the flotation cell. This approach ensure the study of the dispersed phase as ensemble averaged and modeled with an Eulerian equation similarly to the continuous phase. In the flotation process the phosphate volume fraction is relatively high.

The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow. As a band aid solution this is correct, but as the ultimate correction it is not. The purpose of the air is to provide the medium that the collector attaches and to provide a surface for the mineral to be floated away on.
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …
