Flotation Center Launder UpgradeMetso Outotec

The new froth cone and outer crowder maximizes froth recovery and creates a thicker more stable and more productive froth. Both the cone and crowder push the froth towards the center launder. This is especially important near the end of the circuit after all the fast floating and well-liberated particles have been reported to the launders.

Experimental and numerical studies of launder

 · Flotation cells that only include a launder along the periphery of the tank may require the froth in the centre to travel long distances until reaching the weir. This can be avoided by increasing the number of launders which may include the use of internal launders to collect froth at the top of the cell and not only at the periphery of the tank.
