Flotation cells: Selecting the correct concentrate launder design ...

So which of these parameters is most important for cell selection? If the residence time is met with a certain cell selection but the froth carry rate or froth lip loading are exceeded, what are the options? One option would be to increase the number of flotation cells to increase the froth surface area or concentrate lip length.
