Abstract: A method of controlling a froth flotation cell in a froth flotation circuit for separating substances comprises periodically carrying out a control routine to maximise froth stability during the operation of the cell. The control routine comprises changing the gas flow rate to the cell in a series of steps and assessing the froth stability at each gas flow rate and continuing the step changes in the gas flow rate until the froth stability is a peak froth stability or is within a predetermined range of the peak froth stability of the cell.
