A froth flotation cell for treating mineral ore particles suspended in slurry and for separating the slurry into an underflow and an overflow, the froth flotation cell comprising a tank with a centre and a perimeter, a gas supply for introducing flotation gas into the slurry to form froth, a first froth collection channel surrounding the perimeter of the tank so that an open froth surface (A f) is formed inside the first froth collection channel, a second froth collection channel arranged between the centre of the tank and the first froth collection channel and substantially concentric with the first froth collection channel, the second froth collection launder comprising a first froth overflow lip facing towards the centre of the tank, a first radial froth collection launder comprising a first radial froth overflow lip arranged to allow overflow of the slurry and/or of the froth into the first radial froth collection launder, the first radial froth collection launder extending from the first froth collection channel towards the second froth collection channel and in fluid communication with the first froth collection channel, and a second radial froth collection launder comprising a second radial froth overflow lip arranged to allow overflow of the slurry and/or of the froth into the second radial froth collection launder, the second radial froth collection launder extending from the first froth collection channel towards the second froth collection channel and in fluid communication with the first froth collection channel, wherein the froth flotation cell has a pulp area (A p), defined as effective open area of the froth flotation cell available for froth formation, of at least 15 m 2, measured at the height of a mixing area, defined as the part or zone of the flotation tank in vertical direction where the slurry is agitated, and wherein froth collected into the second froth collection channel is arranged to be directed to the first froth collection channel, characterized in that the froth flotation cell further comprises a radial froth crowder comprising a crowding sidewall arranged to extend above the froth such that overflow of the froth is prevented, the radial froth crowder extending from the second froth collection channel to the first froth collection channel, the radial froth crowder arranged between the first radial overflow lip of the first radial froth collection launder and the second radial overflow lip of the second radial froth collection launder, and in that the open froth surface (A f) between froth collection channels (21, 22) and radial froth collection launders (23a, 23b) is divided into two open froth subsurfaces (A fa, A fb) by the radial froth crowder, the two open froth subsurfaces (A fa, A fb) being completely separated by the radial froth crowder. a tank with a centre and a perimeter, a gas supply for introducing flotation gas into the slurry to form froth, a first froth collection channel
