##tihuan2##The transport times can be quite significant especially in plant-scale flotation cells as the bubble–particle aggregates have to move over large distances. This may be one of the reasons why flotation rates are much better in laboratory batch cells where the bubble–particle aggregates have much shorter distances to reach the froth layer.
