Flotation cells: Selecting the correct concentrate launder design
As with the internal peripheral launder the froth is pushed to the launder by the froth crowder. This design, however, provides more froth surface area. The external peripheral launder does not consume cell volume, so the effective cell volume for flotation is also higher. This launder is predominantly used on smaller TankCells.
