A practical approach to plant-scale flotation optimization

The only way to reliably know the amount of air entering a flotation cell is to physically measure it with some kind of probe.

However, it is possible to generate linear ...

Efficient and productive froth flotation from FLS

Self-aspirated cells are simpler in design and generally more energy efficiency, as they do not require an external air supplier; however, forced-air cells offer tighter control over air flow, which can enhance flotation performa nce, and higher-volume air injection for large capacity operations.
