Abstract: A flotation cell for treating particles suspended in slurry and for separating the slurry into an underflow and an overflow is disclosed. The flotation cell includes a flotation tank including a center, a perimeter, a bottom, and a side wall; and a launder and a launder lip surrounding the perimeter of the flotation tank. The flotation tank further includes blast tubes for introducing slurry infeed into the flotation tank. A flotation line, as well as a use of the flotation line is also disclosed.

Abstract: A froth collection launder for a collection of froth from a mineral flotation includes a first and a second sidewall which are joined to form a bottom including a tip extending along the bottom, the first sidewall including a first end and the second sidewall including a second end at their open ends, at least one of the first and the second ends includes a froth overflow lip, and when the froth collection launder is positioned at its operation position a centre line is located in the middle of the first and the second end in the cross direction (x) of the froth collection launder. The tip is located between the centre line and one of the first and the second end in the cross direction (x) of the froth collection launder and the tip forms the lowest point of the froth collection launder.

Abstract: A froth flotation unit for treating mineral ore particles suspended in slurry includes a tank, a gas supply for introducing flotation gas into the slurry to form froth, and a first froth collection launder including a first froth overflow lip facing towards the centre of the tank. The froth flotation unit has a pulp area of at least 15 m2 measured at a mixing area. The froth flotation unit further includes a second froth collection launder with a first froth overflow lip facing the perimeter of the flotation tank, and a froth blocker arranged between the first froth overflow lip and the second froth overflow lip. A froth flotation line, its use, and a froth flotation method are also disclosed.
