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. A secondary launder, concentric with the outer launder may also be placed near the top of the tank and attached to the second ends of the radial launders. The secondary launder is attached to a dispersing mechanism located around the impeller. The secondary launder is in fluid communication with the radial launders, and the radial launders are likewise in fluid communication with the central launder. This provides a network of launders which collects froth at various locations throughout the flotation cell and causes rapid removal of froth from the flotation cell.
