Introduction. Froth flotation is a critical unit operation widely used to concentrate valuable minerals in mineral processing operations. The basic principle of the process is that addition of reagents causes the surface of valuable minerals to become hydrophobic, so that they attach to bubbles and rise to the surface of the flotation tank, …

Air delivery is obviously a key aspect of flotation. Regardless, in many plants measurement of air rate into individual cells is often lacking, let alone any means to check air distribution inside a cell. This limits the ability to diagnose cell behavior and to manage air delivery to meet metallurgical targets.
