This control algorithm was based on maximising the air recovery – a measurement of froth stability – which was developed and validated in a flotation tank at laboratory scale. Air recovery is defined as the fraction of air entering a flotation cell that overflow as unburst bubbles (Neethling and Cilliers, 2008).

Since the early days of flotation, process technicians have known that the speed at which the froth is recovered over the lip of the cell has a very direct and consistent influence on the grade and recovery of the circuit. No plant would deny that, even to this day, one of the most important aspects of a process technician's job is ensuring that the froth is moving …

Hence Hadler's results implied that there was an interaction effect between air and level. As the froth depth increased, the air rate needed to increase in order to reach the peak air recovery. This indicates that there are combinations of froth depth and air rate which result in optimum flotation performance.
