A method of controlling operation of a froth flotation cell comprises introducing gas into a liquid in the cell, thereby to create a froth on the surface of the liquid, which froth overflows and leaves the cell at an overflow point, wherein the froth has a froth height from the level of the overflow point to the upper surface of the froth, measuring values of the froth height for two values of gas flow rate into the cell, measuring values the velocity at which the froth overflows at the overflow point for two values of gas flow rate into the cell, calculating a gas flow rate into the cell that optimises gas recovery, by treating the measured values of froth height and measured values of froth velocity independently, and setting the gas flow rate into the cell to be the calculated flow rate into the cell that optimises gas recovery.
