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.

A froth flotation cell comprising a tank and an impeller rotatably disposed in the tank for suspending solids and dispersing air in a pulp phase or slurry in the tank, thereby generating froth from the pulp phase. A plurality of radially oriented launders are placed near the top of the tank and have one end connected to an outer launder adjacent the outer periphery of the tank.

In a central donut launder the froth flows into both sides of the launder. The froth on one side is pushed to the launder by the froth crowder, with the froth on the other side pushed to the launder by tapered tank walls at the top of the cell. The launder is designed for optimum froth surface area on both sides. The …

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 . 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.
